Miscellaneous: Developer credits

Nice Code is believed to have programmed officially licensed ports of Atari 2600, Atari 7800, and Intellivision games to Famicom hardware for use in plug & play systems. The original Intellivision ports were included on two of Techno Source's Play Power plug & plays, which were released as early as 2003, while the Atari ports were most prominently featured on the first Atari Flashback console released in 2004. Many of these ports were later altered and included on multi-game systems such as generic plug & plays, which namely removed copyrighted material to avoid potential legal issues. This page serves to list all known Intellivision and Atari ports from Nice Code and their subsequent generic variants.

Nearly all of the Nice Code Intellivision ports were hacked into unbranded/unlicensed variants, but only the ports of more obscure Atari games received later alterations. Several of these ports are still released to this day under official license, mostly Atari ones. Of note, however, is some of them appear to become more accurate to their original counterparts in later revisions. Additionally, while the known variations of the titles are originally-programmed clones, a fully-coded Intellivision emulator on NES hardware exists, which appears to have been pitched to Nice Code partner Trump Grand.

There are two generic Nice Code releases that are possibly derived from scrapped Atari 2600 ports: Lightning, which is similar to Atari's Street Racer, and Sea Wolf, which is similar to the Tele-Games-exclusive Submarine Commander. Additionally, it is speculated that a separate set of Atari 2600 ports based on Activision and Imagic games was also produced by Nice Code (likely for Techno Source), but ultimately never released. This is evidenced by four generic Nice Code titles being closely derived from Activision/Imagic titles (Aim Cruise, Candy Workshop, Ice Ocean, and Little-Witch).

There are several other Intellivision ports to Famiclone hardware as well, but they do not seem to be affiliated with Nice Code. These are found on the Intellivision X2 plug & plays, and were produced by ex-Subor developers.

Intellivision games[]

The Intellivision plug & play ports are often considered rather poor adaptions of their original counterparts. The ports are often missing gameplay modes and features (such as Snafu only having one CPU opponent), and their control schemes are often reworked to better fit the NES controller layout. While all of the games closely mimic their Intellivision counterparts' graphics, none of them attempt to recreate the games' music and sound effects. Every Intellivision port (with the odd exception of Super Pro Hockey) uses the same generic sound effects, with no music added whatsoever. The games themselves are based on a mixture of Mattel Electronics (1979-1983) and INTV Corp. (1984-1990) releases, with the INTV Corp. versions often (though not always) being used as basis over the originals.

The majority of hacked versions feature a "Copyright 2004" legal notice, accompanied by a near-illegible logo reading "TWLS", with an unclear image presented above it. It is unknown who the TWLS entity is, other than that they are solely credited in the hacked Intellivision ports and not in any other known Nice Code-affiliated productions. Some of these titles have variants that remove the TWLS logo, and space out the "Copyright 2004" credit in its place.

Astrosmash[]

Title screen

Based on the 1981 Mattel Electronics release.

Defend Homestead[]

粉碎陨石(改版) Defend Homestead (Astro Smash Hack)

Title screen

Predates the "TWLS" hacks, featuring a "Copyright 2003" legal notice. All graphics are completely redrawn in comparison, though noticeably uses a "blockier" art style than later hacks, similar to the original port's faux-Intellivision graphics. This game may have been released as a "pair" with IQ Champion.

This variant is uncommon, and is currently only known to have appeared in PocketNES compilations for Game Boy Advance. It is presumed that the game originates from another (unknown) source.

Air Alert (TWLS)[]

Not to be confused with the Xevious hack of the same name.

炮击(改版) Aether Fighter (Cannonade Hack) (2005SR09392)

Title screen

Changes the asteroids to robots. It is unknown if this is a version fully customized by Waixing, or if it is an obscure preexisting variant. A Waixing VT03 release under this name is actually a variant of a completely different game (being based on Space War); both games share the same "copyright", with a notice of "2005SR09392".

Earth Fighter (VT03)[]

炮击(改版) Earth Fighter (VT03) (Cannonade Hack)

Title screen

A VT03 conversion; the graphics are completely redrawn in comparison to other versions. Notably, this version was ported to VT168 hardware by Wellminds and it is only known to exist on the 268-in-1 Portable Game Station.

Trooper[]

炮击(改版) Trooper (Cannonade Hack)

Title screen

Loosely connected to an "advanced" set of Inventor hacks, which is seemingly connected to Nice Code and/or Waixing. Changes the asteroids into men parachuting down, similarly to some of the Falling variants. This variant has no copyright notation.

Buzz Bombers[]

灭蜂人(美版) Buzz Bombers (U) (V1)

Title screen

Based on the 1983 Mattel Electronics release.

IQ Champion[]

灭蜂人(改版) IQ Champion (Buzz Bombers Hack) (Boy)

Title screen

Predates the "TWLS" hacks, featuring a "Copyright 2003" legal notice. The Intellivision credit is changed to read "Dongxin techno", a literal Chinese-to-English romanization of Nice Code's company name. The bug spray can is changed to a boy in a helmet; the enemies are still bees and wasps, but are completely redrawn compared to the original. The beehives are changed to be shaped like hearts. Oddly, the "Prepare to Start" text is changed to read "Presents to Start"; this error would carry over into later variants. This game may have been released as a "pair" with Defend Homestead.

IQ Champion ("tank" variant)[]

灭蜂人(改版) IQ Champion (Buzz Bombers Hack) (Tank) (p1)

Title screen

Replaces the playable character from the original IQ Champion variant with a tank, both on the title screen and in-game. The bees are replaced with small flying vehicles. This variant is only known to appear on an unbranded 25-in-1 plug & play.

IQ Champion ("Firecore" affiliate)[]

Virtually identical to the original version, but the player sprite is changed to a small tank (which is different than the one in the 25-in-1 variant). The title screen artwork and life indicators of the boy in the helmet are unaltered. This variant is only known to appear on the 100-in-1 "D-CAT 8" system.

Hexapod (TWLS)[]

灭蜂人(改版) Hexapod (Buzz Bombers Hack)

Title screen

Changes the bees to hexapods and the wasps to ladybugs; the can of bug spray is traced over the original sprite (with higher pixel count/added colors). This variant adds music to the title screen, which is a rendition of "Norwegian Dance no. 2" by Edvarg Grieg.

Man in Red (Power Joy)[]

灭蜂人(改版) Man in Red (Buzz Bombers Hack)

Title screen

Changes the player to a man wielding a gun who shoots at UFOs; the beehives are removed entirely. The originally-animated title and intermission screens are replaced with static ones; a change that also applies to several further variants. Credited to Power Joy Ltd.

灭蜂人(改版) Man in Red (VT03) (Buzz Bombers Hack)

Title screen

VT03 conversion of 8-bit Man in Red; graphics are given added colors/shading. Uses similar player/enemy graphics to the original, with fully-redrawn background graphics. Credited to Power Joy Ltd.

VT03-enhanced version of the 8-bit version; graphics are given added colors/shading. This variant also adds a music track that plays throughout the entire game.

Little Indian (Qi Sheng Long, VT03)[]

灭蜂人(改版) Little Indian (VT03) (Buzz Bombers Hack)

Title screen

Based on the Man in Red variant; changes the player to an Indian boy who shoots arrows at birds. The bird on the title screen is modified from the "Pikachu" variant of Eggs.

Archer (Waixing, VT03)[]

灭蜂人(改版) Archer (VT03) (Buzz Bombers Hack)

Title screen

Identical to Qi Sheng Long's Little Indian visually, but has added music. Ironically, the game seems to be named after a completely unrelated Space War hack titled Archer; implying that Waixing confused two actually-separate games as being the same title. Both games share the same "copyright", with a notice of "2005SR09394".

Orchard Kavass[]

灭蜂人(改版) Orchard Kavass (Buzz Bombers Hack)

Title screen

Loosely connected to an "advanced" set of Inventor hacks, which is seemingly connected to Nice Code and/or Waixing. Changes the player into a girl and the background into a giant tree; the enemies are poor recolors of the worms from the NES version of Donkey Kong 3.

Orchard Kavass (alternate revision)[]

Known to be included on the FC Pocket 638-in-1. Compared to the above version, this variant uses a more simplistic tune on the title screen and in-game.

Top Golf (TWLS)[]

顶级高尔夫(亚洲版) Top Golf (As)

Title screen

Graphics are rounded out with a higher pixel count; the trees are completely redrawn. The (second) title screen animation still reads "Chip Shot", and the main game mode is still labeled as the "INTV Tourney".

Hover Force[]

盘旋之力(美版) Hover Force (U)

Title screen

Based on the 1986 INTV Corp. release.

Airial Hero (TWLS)[]

盘旋之力(改版) Airial Hero (Hover Force Hack) (TWTS)

Title screen

All in-game graphics are completely redrawn compared to the original, using a cityscape reminiscent of the Pokémon games. This hack retains the difficulty screen and opening intro; the graphics in the opening appear to be traced over the original sprites (with higher pixel count/added colors).

Airial Hero (Power Joy)[]

盘旋之力(改版) Airial Hero (Hover Force Hack) (Power Joy)

Title screen

Uses virtually identical graphics to the TWLS version, but the crosshair is redrawn. The difficulty screen and opening intro are removed. Credited to Power Joy Ltd.

Title screen

Based on the Power Joy version of Airial Hero. The enemy graphics are changed to UFOs, but the cityscape is unaltered. This variant has no copyright notation.

Attacking (Waixing)[]

盘旋之力(改版) Attacking (Hover Force Hack)

Title screen

Based on the Power Joy version of Airial Hero; some graphics are fully redrawn, while others are simplified. Some variants of Attacking feature custom music while others do not. It is unknown if this is a version fully customized by Waixing, or if it is an obscure preexisting variant. The fighter jet seen on the title screen resembles a smaller version of the jet from Explorer.

A version credited to Timemax is present in their post-2022 game set (with no further alterations), based on the variant with custom music; it is unknown if this is an authorized release.

Aerial Hero[]

盘旋之力(改版) Aerial Hero (Hover Force Hack)

Title screen

Basic title screen variant of the Power Joy version of Airial Hero, correcting the game's misspelled title.

Motocross[]

摩托车越野赛(美版) Moto-Cross (U)

Title screen

Based on the 1982 Mattel Electronics release.

All graphics are completely redrawn compared to the original. The player is changed to a soldier, and the robot and spider are changed to tanks from Battle City. Bats are changed to orange balloons.

Warrior (TWLS, alternate revision)[]

Uses the same title screen as the original TWLS version, but completely replaces all in-game graphics, including changing the player to a robot. The "Copyright 2004" notice is removed, but the TWLS logo itself is intact.

Warrior (Play Vision/Fun Station)[]

Virtually identical to the original TWLS revision, but some color values are altered. This variant originates from the "Play Vision"/"Fun Station" game set; it was later featured in Waixing's set with no further changes.

Warrior (Waixing, VT03)[]

夜行者(改版) Warrior (Waixing) (VT03) (Night Stalker Hack)

Changes the player and enemies into monster characters. It is unknown if this is a version fully customized by Waixing, or if it is an obscure preexisting variant.

夜行者(改版) Battlefield (VT03) (Night Stalker Hack)

Title screen

VT03-enhanced version of the 8-bit version; graphics are given added colors/shading.

Robot Maze[]

恶魔末日(改版) Robot Maze (Devildom Doom Hack)

Title screen

Basic title screen variant of Devildom Doom. Created as part of a bulk-retitling of games featuring "violent" (or otherwise less child-friendly) words, likely developed for the European market.

Pinball[]

Based on the 1983 Mattel Electronics release. The physics in this port are extremely stilted and unrealistic, with the ball effectively moving in straight directions (vertically/horizontally or diagonally). The later NES-based port from the ex-Subor developers features much more accurate physics.

Polk (TWLS)[]

Graphics are rounded out with a higher pixel count; the dog icons are replaced with stars. The ball is given four diagonal lines around its edges, though is otherwise unaltered. The title screen artwork is repurposed from a piece of clipart.

Polk (Waixing)[]

Basic copyright revision of the TWLS version, adding a "2005SR04631" legal notice; the game is otherwise unaltered.

Pinball (TWLS)[]

Basic title screen variant of the Polk version (which it appears to postdate, despite using the original Pinball name).

Pinball (Play Vision/Fun Station)[]

Based on the TWLS version, but some graphics are modified in comparison (including removing the circular pattern on the playfield). This variant originates from the "Play Vision"/"Fun Station" game set; it was later featured in Waixing's set with no further changes.

Pinball (Waixing, VT03)[]

VT03-enhanced version of the TWLS 8-bit version; graphics are given added colors/shading. This variant also adds a music track that plays throughout the entire game.

Polk (Timemax)[]

Reportedly uses different graphics than other variants. Released as part of the post-2022 Timemax game set.

Shark! Shark![]

Based on the 1982 Mattel Electronics release.

Fish War (TWLS)[]

Uses similar theming to the original game, but features entirely redrawn graphics in comparison. What is believed to be the original version uses somewhat-realistic fish designs. Features a bass on the title screen.

Fish War (TWLS, alternate revision)[]

Compared to the above revision, this version uses more cartoonish fish designs with thicker outlines. Features a front-facing angry shark on the title screen.

Fish War (Waixing)[]

Identical to the "alternate" version of the TWLS release, though Waixing's release edits the music to play in-game rather than just on the title screen. Features a "2005SR05462" legal notice.

Hexapod War (TWLS)[]

Changes the fish to hexapods, including worms and snails.

Inkfish (TWLS)[]

Changes the player to a squid, with the other fish changed to different aquatic life (such as dolphins and seahorses).

A version credited to Timemax is present in their post-2022 game set (with no further alterations); it is unknown if this is an authorized release.

Exist[]

Loosely connected to an "advanced" set of Inventor hacks, which is seemingly connected to Nice Code and/or Waixing. Changes the graphics into bugs and rats; some background assets are taken from Teenage Mutant Ninja Turtles: Tournament Fighters.

While the connected Orchard Kavass and Trooper hacks are common in Waixing-published game sets, Exist is rarely seen in Waixing's releases for unknown reasons.

A version credited to Timemax is present in their post-2022 game set (with no further alterations); it is unknown if this is an authorized release.

Shark (VT03)[]

A VT03 conversion; the graphics are completely redrawn compared to other versions. Features highly detailed fish sprites and backgrounds.

Exist (Waixing, VT03)[]

A VT03 conversion. Uses the same player sprites as Shark, but has simplified backgrounds; suggesting that this variant was built off of that version, or a relative to it that has yet to be documented. Named after an otherwise-unrelated 8-bit version, likely to make the two games share the same "copyright".

Killing Invader (Timemax)[]

Reportedly uses different graphics than other variants. Released as part of the post-2022 Timemax game set.

Hungry Fish[]

Basic title screen variant of Hexapod War (despite that version not using fish graphics).

Fish Food (Waixing, VT03)[]

Basic title screen variant of the VT03 version of Exist. It uses artwork from the film poster for Finding Nemo, with no title logo present. Only known to exist on the VT03 Senario 101-in-1.

Shark War (Timemax)[]

Basic title screen variant of the Waixing release of Fish War; released as part of the post-2022 Timemax game set. The shark's back has "MF" written on it; this is also present in Pair Card.

Skiing[]

Based on the 1980 Mattel Electronics release U.S. Ski Team Skiing, with its name changed to remove the U.S. Ski Team trademark. While a trademark-less INTV Corp. version was released in 1987 (Mountain Madness: Super Pro Skiing), the plug & play port is based on the original 1980 version.

Surfg Sport (TWLS)[]

Changes the player to a man on a surfboard, who slaloms through signs in the water. The menu select screen still refers to the players as "Skiers". Surfg Sport was originally produced with a title screen, though most releases remove the screen entirely; likely to convert the game to NROM/"mapper 0" (whereas the original uses CNROM-like coding).

Sur LC (Waixing)[]

Identical to Surfg Sport visually (specifically the revision with its title screen removed), but adds a music track that plays throughout the entire game.

Sur LC (Waixing, VT03)[]

VT03-enhanced version of Waixing's 8-bit version; graphics are given added colors/shading.

Skiing (VT03)[]

A VT03 conversion; the graphics are completely redrawn in comparison to other versions. Retains the original game's skiing theme rather than surfing.

Surfer[]

Basic title screen variant of Surfg Sport. The "E" in the game's title is poorly modified from the "G" in "Surfg", with a large chunk of the letter taken out.

Aqua Skiing (Timemax)[]

Variant of the Waixing release of Sur LC that adds a title screen; released as part of the post-2022 Timemax game set.

Slam Dunk! Super Pro Basketball[]

Based on the 1987 INTV Corp. release. Despite having hacked versions, they are uncommon on plug & play systems for unknown reasons.

Basketball (TWLS)[]

All graphics are modified, and appear to be traced over the original sprites (with higher pixel count/added colors).

A version credited to Timemax is present in their post-2022 game set (with no further alterations); it is unknown if this is an authorized release.

Basketball (VT03)[]

A VT03 conversion of the TWLS version; the graphics are completely redrawn in comparison. Oddly, the title screen appears to feature a small, centered image of Nature Clan that is partly obscured by a digitized image of a basketball player. The title screen also features text reading "CHAMPING2006" [sic].

Slap Shot! Super Pro Hockey[]

Based on the 1987 INTV Corp. release. Oddly, all of the sounds are taken from Antarctic Adventure for the Famicom, rather than using the generic sounds of all other Intellivision ports. The known hacked versions retain the credits screen, albeit with references to INTV Corp. blanked out.

Slap Shot! Super Pro Hockey (TWLS)[]

All graphics are modified, and appear to be traced over the original sprites (with higher pixel count/added colors). This release does not explicitly credit TWLS in-game (though presumably originates from them).

Slap Shot! Super Pro Hockey (Waixing)[]

Based on the TWLS version, but features slightly modified player and background sprites (including rounding out the sides of the stadium).

Ice Hockey (VT03)[]

A VT03 conversion of the TWLS version; the graphics are completely redrawn in comparison.

Ice Hockey (Timemax)[]

Variant of the Waixing release of Slap Shot! Super Pro Hockey that adds a (second) title screen; released as part of the post-2022 Timemax game set.

Snafu[]

Based on the 1982 Mattel Electronics release. While the original Snafu port only has one CPU opponent, the hacked versions have two opponents; the actual Intellivision game has three opponents. The original port also only has four game modes, whereas the hacked variants have eight game modes.

Shrew Mouse (TWLS)[]

Features completely redrawn graphics. This version adds life indicators in the top-left corner, which the player/opponents can bizarrely crash into. Additionally, the top of the playfield is not walled off; making its outer edge cut off by the TV overscan, and resulting in opponents appearing invisible if/when they enter that area.

Shrew Mouse (TWLS, alternate revision)[]

This variant removes the life indicators, though the issue with the top of the playfield is still present. Features a redrawn title screen with added music; the title artwork is possibly a modified picture of The Little Mole.

Shrew Mouse (TWLS, alternate revision, 25-in-1)[]

Based on the later TWLS revision, but features slightly modified graphics in comparison, including changing the outer walls to a brick pattern. This variant is only known to appear on an unbranded 25-in-1 plug & play.

Star (Waixing)[]

Based on the earlier TWLS revision; changes all graphics into star patterns. Adds a music track that plays throughout the entire game; the same track would also be used in Waixing's Table Tennis.

Star (Waixing, VT03)[]

VT03-enhanced version of the Waixing 8-bit version; graphics are given added colors/shading.

Chain Star (Waixing)[]

Basic title screen variant of Star.

Space Armada[]

Based on the 1981 Mattel Electronics release. When the aliens are descending, they retain the full, six-row hitbox, regardless of if any surrounding aliens are defeated. This leads to aliens towards the middle of the screen, or the opposing ends of the playfield, not reaching the ends of the screen; making the game very difficult to play. This error was corrected in the later Space Armada ports by the "ex-Subor" developers.

First Defender (TWLS)[]

Features completely redrawn graphics, including changing the player's ship into a tank. Adds music to the title screen, which is a rendition of "Norwegian Dance no. 2" by Edvarg Grieg.

Icarian (TWLS)[]

Basic title screen variant of First Defender. This variant features a glitch that messes up the scrolling of the bases at the bottom of the screen.

Icarian (VT03)[]

A VT03 conversion of the Icarian variant; the graphics are completely redrawn in comparison.

M-Day (Waixing)[]

Changes the enemies into front-facing planes and hot air balloons. The UFO sprite is blanked out.

Sea Monster (Qi Sheng Long, VT03)[]

A VT03 conversion; graphics are completely redrawn in comparison to other versions.

M Day (Waixing, VT03)[]

Identical to Qi Sheng Long's Sea Monster visually, but has added music. Named after an otherwise-unrelated 8-bit version, likely to make the two games share the same "copyright".

Space Battle[]

Based on the 1980 Mattel Electronics release. All hacked variants, with the exception of Base, remove the map screen.

Close Quarters (TWLS)[]

Features completely redrawn graphics; taking place on land instead of in outer space, with a psuedo-3D effect on the ground.

Aimless[]

Based on the Close Quarters variant; changes the enemy ships into dragons, and recolors the ground to make it resemble water (with islands in the distance). Features a "Copyright 2004" legal notice without the TWLS logo; the game still features HEX data for the Close Quarters title screen, albeit with its graphic tiles blanked out.

A version credited to Timemax is present in their post-2022 game set (with no further alterations); it is unknown if this is an authorized release.

Airial Hero[]

Based on the Close Quarters variant; changes the enemy ships into UFOs, and uses different colored backgrounds. Features a "Copyright 2004" legal notice without the TWLS logo.

Airial Hero (Waixing)[]

Basic copyright variant adding a Waixing legal notice ("2005SR09390" in some revisions, "200518009" in others); the game is otherwise unaltered.

Fighter Jet[]

Features a static backdrop showing a boat, lacking the psuedo-3D ground. This variant has no copyright notation.

A version credited to Timemax is present in their post-2022 game set (with no further alterations); it is unknown if this is an authorized release.

Base[]

Retains the map screen from the original game, which all other variants remove. The starscape is completely removed in this hack, making backgrounds appear blank; the enemy ships use the same sprites as Close Quarters. This variant has no copyright notation.

Pearl Harbor (VT03)[]

A VT03 conversion; the graphics are completely redrawn in comparison to other versions. Features a static backdrop showing Pearl Harbor being bombed, with the enemy ships changed to Japanese WWII planes.

Close Quarters (Waixing, VT03)[]

A VT03 conversion; graphics are given added colors/shading. Uses similar enemy sprites to the 8-bit version, with fully-redrawn backgrounds showing a cityscape. Also changes the game's music track. Possibly based on an obscure preexisting variant, due to its similarities to the Shenzhen Niutai version (which itself is likely not connected to Waixing's version).

Close Quarter (Shenzhen Niutai, VT03)[]

A VT03 conversion; graphics are given added colors/shading. Uses similar enemy sprites to the 8-bit version, with fully-redrawn backgrounds showing a cityscape. Possibly based on an obscure preexisting variant, due to its similarities to the Waixing version (which itself is likely not connected to Niutai's version).

Harbor (VT03)[]

Basic title screen variant of Pearl Harbor.

Space Hero (Waixing)[]

Basic title screen variant of Airial Hero.

Aerial Hero (Waixing)[]

Basic title screen variant of Airial Hero, correcting its typo. Only known to exist on the VT03 Senario 101-in-1.

Dune War (TWLS)[]

All graphics are completely redrawn compared to the original. The player controls a soldier running in a desert, shooting down enemy airplanes.

Dune War (Power Joy)[]

Basic copyright revision of the TWLS version; unconventionally, it features a "Power Joy Ltd" legal notice with the Nature Color logo graphic. The game is otherwise unaltered.

Dune War (Play Vision/Fun Station)[]

Virtually identical to the TWLS version, but the score/life indicator uses a different font. This variant originates from the "Play Vision"/"Fun Station" game set; it was later featured in Waixing's set with no further changes.

Dune War (Waixing, VT03)[]

VT03-enhanced version of the TWLS 8-bit version; graphics are given added colors/shading. This variant also adds a music track that plays throughout the entire game.

Sand Shot[]

Basic title screen variant of Dune War. Created as part of a bulk-retitling of games featuring "violent" (or otherwise less child-friendly) words, likely developed for the European market.

StarAttack (TWLS)[]

All graphics are completely redrawn compared to the original. The spaceman is changed into an orange spaceship; the ship itself is only drawn to move in four directions, with a small cannon illustrating diagonal movement. The title screen shows an alien piloting a UFO.

StarAttack (Qi Sheng Long)[]

Based on the TWLS version; changes the ship graphics to properly rotate in eight directions rather than four directions. Some graphics were not altered correctly, resulting in glitchy animated tiles; though the game is overall much clearer visually than the TWLS version. The UFO on the title screen is replaced with a green spaceship.

StarAttack (Waixing)[]

Identical to the TWLS version visually, but adds a music track that plays throughout the entire game.

Basic title screen variant of the Waixing release of StarAttack; released as part of the post-2022 Timemax game set.

Spiker! Super Pro Volleyball[]

Based on the 1989 INTV Corp. release. Oddly, at least two Atari plug & play releases also use this game, listing it as "RealSports Volleyball" (a proper Atari 2600 game) in the menu. In the Atari releases, credits to INTV Corp and the "Spiker!" text are removed.

Volleyball (TWLS)[]

All graphics are modified, and appear to be traced over the original sprites (with higher pixel count/added colors). The originally-animated title screen is replaced with a static one; this also applies to all subsequent variants.

Volleyball (Waixing)[]

Based on the TWLS version, but the title screen and in-game background graphics are altered. This variant also adds a music track that plays throughout the entire game. A seemingly-earlier revision features an unconventional "2005 Wai Xing" copyright notice; an alternate revision features a more typical "2005SR12751" notice.

Beach Volleyball (Qi Sheng Long, VT03)[]

A VT03 conversion of the TWLS version; the graphics are completely redrawn in comparison. This variant uses an image traced from Volume 1 of the manga Love Hina.

Beach Volley (Timemax)[]

Basic title screen variant of the Waixing release of Volleyball; released as part of the post-2022 Timemax game set.

Star Strike[]

Based on the 1981 Mattel Electronics release. The game's pseudo-3D visuals are recreated rather poorly, quickly flashing between colors rather than using a gradual shifting effect. This game is not known to have received any hacked variants.

Sub Hunt[]

Based on the 1982 Mattel Electronics release.

Silent Hunter (TWLS)[]

Graphics are rounded out with a higher pixel count; the backgrounds appear to be fully redrawn.

Silent Hunter (Waixing, VT03)[]

Naval Battle (Timemax)[]

Basic title screen variant of the Waixing release of Silent Hunter; released as part of the post-2022 Timemax game set.

Super Pro Football[]

Based on the 1986 INTV Corp release. Despite having hacked versions, they are uncommon on plug & play systems for unknown reasons (possibly due to American football's unpopularity in other regions).

Football (TWLS)[]

All graphics are modified, and appear to be traced over the original sprites (with higher pixel count/added colors). Adds an additional title screen that appears before the stadium screen animation (which still reads "Super Pro Football" in the hacked version).

Foot Ball[]

Appears to be based on the TWLS version, but features fully redrawn graphics in comparison. This variant has no copyright notation.

Thin Ice[]

Based on the 1986 INTV Corp. release of Duncan's Thin Ice, a canceled Mattel Electronics production.

Thin Ice (TWLS)[]

Retains the name of the original Intellivision game. All graphics are completely redrawn compared to the original, with the player controlling a rabbit being chased by a wolf. The dancing penguins are changed to various different objects, such as skiing bears and bouncing mushrooms. The originally-animated title screen is replaced with a static one; this also applies to all subsequent variants.

Thinice (VT03)[]

VT03-enhanced version of the TWLS 8-bit version; graphics are given added colors/shading. Uses similar in-game graphics to the 8-bit version, with a fully-redrawn title screen.

Horrible Area (Waixing)[]

Changes the player to a human boy, with all enemies changed to monsters and ghosts; seemingly intended to be set in a graveyard. It is unknown if this is a version fully customized by Waixing, or if it is an obscure preexisting variant.

Lemon Brat (Qi Sheng Long, VT03)[]

Changes the player into a yellow blob with a pink bow, who vaguely resembles Ms. Pac-Man. The player is chased by a seal, similarly to the original Thin Ice; the enemy sprites are modified from the VT03 Thinice variant. Likely released as a "pair" with Warrior Lemon.

Horrible Area (Waixing, VT03)[]

Identical to Qi Sheng Long's Lemon Brat visually, but has added music. Named after an otherwise-unrelated 8-bit version, likely to make the two games share the same "copyright".

Snow Day[]

Zombie (Waixing)[]

Basic title screen variant of the standard Famicom/NES Waixing version of Horrible Area.

Terror Zone (Timemax)[]

Basic title screen variant of the Waixing release of Horrible Area; released as part of the post-2022 Timemax game set.

Thunder Castle[]

Based on the 1986 INTV Corp. release.

Dark Castle (Play Vision/Fun Station)[]

Virtually identical to the TWLS version, but the dragon sprite is more detailed. This variant originates from the "Play Vision"/"Fun Station" game set; it was not the basis for Waixing's release of the game.

Dark Castle (Waixing)[]

Identical to the TWLS version visually, but adds a music track that plays throughout the entire game. The music in question is a rendition of the title screen music from the unlicensed Sega Mega Drive game Smart Mouse.

Mad Tank[]

Features completely redrawn graphics, with the player and dragon changed to tanks in a forest. This variant has no copyright notation.

Weird Castle (Timemax)[]

Basic title screen variant of the Waixing release of Dark Castle; released as part of the post-2022 Timemax game set.

Tower of Doom[]

Based on the 1987 INTV Corp. release of Advanced Dungeons & Dragons: Tower of Mystery, a canceled Mattel Electronics production. Oddly, most of the hacked variants retain copyright notices to "INTV Corp."; despite that the unhacked Tower of Doom ROM only denotes this as "INTV".

Tower (TWLS)[]

Graphics are rounded out with a higher pixel count; a number of sprites from the original game are unaltered. The lanterns above the staircase are changed to green heads. While referred to as just "Tower" in the multicart menus, all references to the Tower of Doom name via dialogue are retained. This release does not explicitly credit TWLS in-game (though presumably originates from them).

Tower (Waixing)[]

Identical to the TWLS version visually, but adds a music track that plays throughout the entire game.

Vectron[]

Based on the 1983 Mattel Electronics release.

World Championship Baseball[]

Based on the 1986 INTV Corp. release of All-Star Major League Baseball, a canceled Mattel Electronics production. The plug & play port has its title screen read "World Championship Baseball", whereas the original Intellivision release still had its title read "All-Star Major League Baseball" in-game.[1]

Baseball (TWLS)[]

All graphics are modified, and appear to be traced over the original sprites (with higher pixel count/added colors).

Baseball (Play Vision/Fun Station)[]

Uses the same title screen and background graphics as the TWLS version, but the player sprites are fully redrawn. This variant originates from the "Play Vision"/"Fun Station" game set; it was later featured in Waixing's set with no further changes.

Baseball (Waixing)[]

Basic copyright revision of the "Play Vision"/"Fun Station" version, adding a "2007SR08456" legal notice; the game is otherwise unaltered.

A version credited to Timemax is present in their post-2022 game set (with no further alterations).

Baseball (Waixing, VT03)[]

A VT03 conversion of the TWLS version; graphics are given added colors/shading. Uses similar background graphics to the 8-bit version, with a fully-redrawn title screen and player sprites. It is unknown if this is a version fully customized by Waixing, or if it is an obscure preexisting variant.

Atari games[]

Adventure[]

Based on the Atari 2600 game. The sound effect for picking up items is taken from Gomoku Narabe Renju.

Air-Sea Battle[]

Based on the Atari 2600 game.

Asteroids[]

Based on the Atari 7800 version. The physics are rather poor compared to the original game, lacking the weighted movement of the player's ship.

Battlezone[]

Based on the Atari 2600 version. Due to Atari selling the Battlezone IP rights (in a 2010s bankruptcy proceeding), this game is not found on newer licensed plug & plays. Ironically, the generic hacked versions are still common to find.

Sudden Strike[]

Features similar theming to the original, but with fully-redrawn graphics; also adds a music track. For unclear reasons, it is extremely difficult to hit targets in this version; a problem not present in the unhacked Battlezone port. The enemy tanks also do not shoot back at the player - making it effectively impossible to either win or lose. Features a "Copyright 2004" legal notice. This game is uncommon on multicarts, likely due to its broken nature; it is only known to appear on the "Firecore" affiliate's systems.

Final Blood[]

Heavily alters the game to not have forwards or backwards movement, with all targets locked to a fixed vertical position. Also adds an HP meter and a time limit. Features a "Copyright 2004" legal notice; likely produced concurrently with a Power Joy Ltd version (as it features a secret credits screen).

Final Fighter[]

Based on the Final Blood variant. Alters the player soldier's portrait, and changes the background to a city rather than hilltops. Also uses a different music track than Final Blood. Possibly originates from the "Firecore"-affiliated game set, though this is not 100% confirmed. This game was also present in the "Play Vision"/"Fun Station" game set, and as such was later released by Waixing (with an altered copyright notice).

Final Fighter (Waixing, VT03)[]

VT03-enhanced version of the 8-bit version; graphics are given added colors/shading.

Frontal Fire (VT03)[]

A VT03 conversion of Final Blood; graphics are given added colors/shading. Uses similar graphics to the original, with a fully-redrawn title screen. While based on Final Blood visually, it uses the music from Final Fighter.

Final Shot[]

Basic title screen variant of Final Blood.

Final Battle (Timemax)[]

Basic title screen variant of the Waixing release of Final Fighter; released as part of the post-2022 Timemax game set.

Breakout[]

Based on the Atari 2600 version.

Canyon Bomber[]

Based on the Atari 2600 game. All known hacks of this port are based on Game B.

Coast Guard[]

Features similar theming to the original, but with fully-redrawn graphics; also adds a music track. Two versions with different copyright notices were produced concurrently: one reading "Power Joy Ltd", and the other reading "Copyright 2004".

Pounce (Qi Sheng Long)[]

Based on the Coast Guard variant; the graphics are completely redrawn in comparison.

Centipede (2600 version)[]

Compared to the 2600 original, the centipede's movement on the title screen is simplified, and the Atari logo rapidly flashes rainbow colors rather than using a scrolling effect. This port is only known to appear on the "Atari Mini Arcade" Centipede tabletop by Blaze; it was not included on the Atari Flashback.

Centipede (7800 version)[]

For unknown reasons, the controls are locked to four directions, whereas the 7800 original (and most other versions of Centipede) have diagonal movement.

Centipede (7800 version, Basic Fun)[]

Basic copyright revision crediting Basic Fun/The Bridge Direct; this version also removes the difficulty select menu. This variant is featured on the "Arcade Classics: Centipede" mini arcade (#03).

Crystal Castles[]

Based on the Atari 2600 version. Features rather poor controls, with the player frequently getting stuck to walls.

Desert Falcon[]

Based on the Atari 7800 version.

Aerial Warfare[]

Changes the falcon and enemies to airplanes. The music when the player loses a life is intact from Desert Falcon. All known versions feature no copyright notation.

Food Fight[]

Based on the Atari 7800 version.

Nut Cracky (Power Joy)[]

Changes the player to a nutcracker and the ice cream cone to a princess; enemy chefs are changed to rats. The game over music and some sound effects are intact from Food Fight. Credited to Power Joy Ltd. The "Eat the Cone!" text is changed to read "To Save the Princess"; several releases erroneously display this screen as "Sav h inc ss" due to poorly blanking out the Power Joy Ltd. notice.

Nut Cracker[]

Basic title screen variant of Nut Cracky.

Gravitar[]

Based on the Atari 2600 version. The ship's physics are somewhat inaccurate, though are much closer to the original than in the Asteroids port.

Haunted House[]

Based on the Atari 2600 game.

Millipede[]

Based on the Atari 2600 version. Unlike Centipede, the player's movement is not locked. The game's sound effects seem to be modified from the original 1980s Famicom/NES version of Millipede.

Missile Command[]

Unlike most of Nice Code's ports of Atari games, this port is based on the arcade version rather than the 2600 port. The player only has one base instead of three, likely due to the NES controller's limited buttons. This port appears on several recent consoles, such as the Atari Plug & Play Joystick by Basic Fun - it was not included on the Atari Flashback.

Planet Smashers[]

Based on the Atari 7800 game.

Aether Mission (Power Joy)[]

Originally produced for (and credited to) Power Joy Ltd. Features similar theming to the original, but with fully-redrawn graphics. The music is unaltered from the original game.

A VT03 conversion of Aether Mission; the graphics are completely redrawn in comparison.

A VT03 conversion of Aether Mission; the graphics are completely redrawn in comparison (and different than the Impossible Mission version).

Saboteur[]

Based on the unreleased Atari 2600 game. Hacked versions split levels 1 and 2 into two different games. The below variants are "level 1"-based versions; for "level 2" versions, see the Spider-Man 2 section.

Ghost Castle[]

Changes the player to a man shooting at ghosts. The Master Robot is changed to what appears to be Dracula. The game only features five floors, whereas Saboteur has six floors; this also applies to all further hacked variants. A music track is also added to the game. Unconventionally, this version features a "Copyright 2004" legal notice with the Nature Color logo graphic.

Danger Mansion (Nature Color)[]

Changes the player to a man wielding a gun in a mansion. Credited to Nature Color Game.

Hell (Waixing)[]

Features a gory title screen showing piles of skeletons in pools of blood. Despite this, the in-game graphics have the player as a purple bug shooting at rabbits and smiling monsters. The Master Robot is changed to a boar. It is unknown if this is a version fully customized by Waixing, or if it is an obscure preexisting variant (it is theorized that a Nice Code-affiliated version appears on a "Play Vision" 49-in-1 plug & play).[2]

Hell (Waixing, VT03)[]

VT03-enhanced version of Waixing's 8-bit version; graphics are given added colors/shading.

Clown's Mission (Qi Sheng Long)[]

Sky Diver[]

Based on the Atari 2600 game.

Changes the player ship to a blue robot, who shoots at asteroids and circular robots instead of planets. The scanner radar and warping segments appear to be removed. Also adds a music track to the game. Two versions with different copyright notices were produced concurrently: one reading "Power Joy Ltd", and the other reading "Copyright 2004".

Space Shuttle[]

A variant from the unknown Firecore-affiliated game set. Uses similar theming to Aether Cruiser, but with fully-redrawn graphics; also uses a different music track.

Galaxy War[]

Virtually identical to Space Shuttle, but has a slightly different HUD design. This variant originates from the "Play Vision"/"Fun Station" game set; it was later featured in Waixing's set with no further changes.

Galaxy War (Waixing, VT03)[]

VT03-enhanced version of the 8-bit version; graphics are given added colors/shading.

Through Lonely (Qi Sheng Long)[]

Basic title screen variant of Aether Cruiser.

Sprintmaster[]

Based on the Atari 2600 game. Some sound effects appear to be lifted from F-1 Race and Excitebike. Unlike other titles, it uses separate CHR-ROM data for graphics.

Warlords[]

Based on the Atari 2600 version.

Yars' Revenge[]

Based on the Atari 2600 game. The "Ion Zone" (the flashing bar in the middle of the screen) is created with imitation graphics, whereas the original 2600 game creates the effect using actual garbled game code.

Yars' Revenge (Blaze)[]

Similar to the above version, but seems to have different sound effects and removes the score screen shown upon starting the game. This variant is only known to appear on the "Atari Mini Arcade" Centipede tabletop by Blaze.
