Connected to Inventor[]
Alienis[]
An advanced hack of Battle City with scrolling levels that was originally developed and released by Shanghai Paradise, a predecessor to Inventor.
Alienis (Power Joy)[]
Presumed to be a basic copyright revision crediting Power Joy Ltd; due to the original Shanghai Paradise release being undumped, this is not 100% confirmed.
Alienis (Waixing)[]
Basic copyright revision of the Power Joy version, adding a "2005SR09639" legal notice; the game is otherwise unaltered.
Alienis (Waixing, VT03)[]
VT03-enhanced version of the 8-bit version(s); graphics are given added colors/shading.
Engine Power (Nice Code)[]
Likely the first fully-hacked variant of the game. Features completely overhauled graphics, with the player and enemy ships changed to tanks. The music is removed, with simplistic shooting sound effects in-game. This game credits Nice Code as "Dongxin Soft". This game was also present in the "Play Vision"/"Fun Station" game set; it was seemingly never republished by Waixing.
Tank 2002[]
Seemingly named in reference to the Tank 1990 hack of Battle City. The game may have been intended to release as a "pair" with Bomberman 2002.
Pulveration (Power Joy)[]
Uses similar graphics to the Engine Power variant (though they are not exact). Adds a loud rumbling sound during gameplay; this was carried over into all further variants. Credited to Power Joy Ltd.
Bugs[]
Changes the player into a ladybug who shoots at other insects. Features a "Copyright 2004" legal notice.
Ice Age (Nice Code)[]
Changes the players into monsters; the background assets are changed to be coated in ice. Credited to Nice Code as "Dongxin Soft".
Monster War (Nice Code)[]
Based on the Ice Age variant; alters the player sprite and changes the enemies into aquatic life (such as fish and lobsters). Credited to Nice Code as "Dongxin Soft".
Monster War (Waixing)[]
Basic copyright revision adding a "2005SR09643" legal notice; the game is otherwise unaltered.
Monster War (Waixing, VT03)[]
VT03-enhanced version of the 8-bit version(s); graphics are given added colors/shading.
Pulver (Waixing)[]
Changes the tanks into bugs; despite the name and theming, it is unrelated to the Pulveration and Bugs variants. Adds a music track that plays throughout the entire game. It is unknown if this is a version fully customized by Waixing, or if it is an obscure preexisting variant.
Pulver (Waixing, VT03)[]
VT03-enhanced version of Waixing's 8-bit version; graphics are given added colors/shading.
Pulveration (VT03)[]
A VT03 conversion of Pulveration; the graphics are completely redrawn in comparison.
Pulverize[]
Basic title screen variant of Pulveration.
Beetle (Waixing)[]
Basic title screen variant of Pulver.
Warship (Waixing)[]
Basic title screen variant of Alienis.
Balloon Fight[]
Fishwar (Nature Color)[]
Tied to a set of "advanced" Inventor hacks, which is seemingly connected to Nice Code and/or Waixing. This hack completely overhauls the graphics; changing the player and enemies to fish who fly using umbrellas (similar to Inventor's Air Umbrella hack). The game features fully replaced music, albeit with no sound effects.
What appears to be the original release features a Nature Color legal notice on the title screen. The Nature Color credit overwrites where the option for the Balloon Trip mode was in the original Balloon Fight; the Balloon Trip mode is disabled entirely in this hack variant.
Fishwar (BBG)[]
Basic copyright variant of the Nature Color version, hacked to credit BBG; the game is otherwise unaltered.
Fishwar (alternate revision)[]
Changes the game's music and re-enables the Balloon Trip mode (labeling it as just "Press Start" in the selection menu). This variant has no copyright notation.
Dragon[]
A basic hack of Fire Dragon that was created by Inventor in 2000.
Dragon (Power Joy)[]
Basic copyright revision of Inventor's Dragon hack, credited to Power Joy Ltd.
Shunting (Power Joy)[]
Changes the dragon to a train; the background color is changed from black to gray. The hack is otherwise unaltered from the Dragon version.
F-22[]
An advanced hack of 1943 that was originally developed and released by Shanghai Paradise, a predecessor to Inventor. While the cut-down Waixing version of the game is common on plug & plays using Nice Code titles, it is otherwise not connected to Nice Code in development.
[]
Title screen.
Basic title screen hack of the 2001 Inventor version of F-22; credited to Power Joy Ltd.
Star Force[]
Hacks are based on the Japanese version.
BoltAction[]
Tied to a set of "advanced" Inventor hacks, which is seemingly connected to Nice Code and/or Waixing. Graphics are completely overhauled compared to the original game. The original release of this hack appears to have credited either Nature Color or Power Joy Ltd (judging by leftover data in the BBG version), though it is unknown which. There is an alternate version with no copyright notation, which reformats the game title with a space (i.e. "Bolt Action"), though is otherwise unaltered.
BoltAction (BBG)[]
Basic copyright variant crediting BBG; the game is otherwise unaltered.
Star Gate[]
Hacks are based on the Japanese version, but are hacked to use both CHR banks; similar to the U.S. version, Defender II.
Star[]
Graphics are extensively altered compared to the original game. The player is changed to a flying dragon, with enemies changed to other dragons and bats; the background is changed to purple marble structures. This hack blanks out the in-game HUD and score counter; it appears these functions were effectively broken from the conversion to using both CHR banks. The music and sound effects are unaltered. This variant has no copyright notation.
This hack sloppily replace the menu select screen with text reading "START" (blanking out all of its options in the process). The two-player and "Game B" modes can still be accessed by pushing Select.
Star (alternate revision)[]
Based on the above hack, but all graphics are completely redrawn in comparison. The dragon is changed to a flying green man, and the marble structures are altered to look more futuristic. The poor selection menu formatting is still present.
Atomic Blast (Power Joy)[]
Tied to a set of "advanced" Inventor hacks, which is seemingly connected to Nice Code and/or Waixing. Built off of Star, though all graphics and music are heavily altered in comparison. The score counter is made visible, though it does not function correctly; only updating the score when a life is lost. The menu select text is fixed compared to the Star revisions. Adds a music track that plays throughout the entire game. Credited to Power Joy Ltd.
Starattack (Power Joy)[]
Virtually identical to Atomic Blast visually, but the music is unaltered from the original Star Gate. Judging from the CHR data, this hack was produced after Atomic Blast was. Credited to Power Joy Ltd.
Connected to Dragon Co.[]
Felix the Cat (Dragon Co.)[]
Little Black Mask[]
A graphical hack of Dragon Co.'s Felix the Cat that changes the player to a shadowy man in a facemask. The majority of enemies and background sprites are intact, though a few details were altered. The story cutscenes are completely removed; though some of the (unused) intro sprites of Felix were still edited into the shadowy character. Some variants of the game start on level 3, with the player partially powered-up at the start; earlier releases still start on level 1. This variant has no copyright notation.
Little Black Mask (Waixing)[]
Basic copyright revision adding a "2005SR10175" legal notice; the game is otherwise unaltered. Based on the variant that starts on level 3.
The Hacker[]
A more elaborate hack of Dragon Co.'s Felix the Cat that was originally created for Famiclone plug & play systems. Replaces Felix the Cat with a character resembling Neo from The Matrix with a ponytail, and completely changes the title screen and level graphics as well as some HUD graphics. The milk bottles are replaced with yellow stars, the golden eggs are replaced with red Internet Explorer icons, and the hearts are replaced with computers. Features a "Copyright 2004" notice on the title screen.
This hack is built off of the Little Black Mask variant, as evidenced by the unused cutscene graphics of the player character from that version remaining intact.
The Hacker (Nature Color)[]
Basic copyright revision crediting Nature Color Game; the game is otherwise unaltered. Oddly, the "Turbo Charger" 18-in-1 plug & play does not use this version (instead using the "Copyright 2004" variant), despite featuring a Nature Color Game splash screen upon booting up the console.[1]
The Hacker/黑客 (Nanjing)[]
A standalone Famicom cartridge version of The Hacker was released in China by Shenzhen Nanjing, titled 黑客 on the box and cartridge. The game is hacked to start on level 2. Compared to other known variants of The Hacker, this version includes cutscenes that appear before levels. The title screen lacks the animation seen in the plug & play variants.
Super Hero (Power Joy)[]
Title screen.
A further modified version of The Hacker, changing the titular hacker to a character whose head is similar to Buzz Lightyear's head from Toy Story, who is featured on the title screen and in-game. Some variants of the game start on level 3, with the player partially powered-up at the start; earlier releases still start on level 1. Credited to Power Joy Ltd.
Super Hero can be found as the second game on DreamGEAR's 75-in-1 controller. It is also commonly found on other DreamGEAR plug & play Famiclone systems as well as those by other manufacturers, such as Trump Grand, Qi Sheng Long or Macro Winners.
The Lion King V: Timon & Pumbaa[]
The following hacks separate the three playable characters from the original game (Simba, Timon and Pumbaa) among individual games, which are likely level hacks. These hacks use the Lion King V engine, but the music and sounds are taken from previous game, Lion King III. The infamous game over screens (e.g. Simba hanging himself) are intact and unaltered.
Howling Killer (Power Joy)[]
Exclusively features Simba as a playable character. The game is hacked to start on level 3. Credited to Power Joy Ltd.
Mongoose Story[]
Exclusively features Timon as a playable character. This variant was featured on Trump Grand's now-defunct website, though is yet to surface on any known consoles.
Super Warthog[]
Exclusively features Pumbaa as a playable character. This variant was featured on Trump Grand's now-defunct website, though is yet to surface on any known consoles.
Tom and Jerry 3[]
Primitive Man (Power Joy)[]
Hack of Tom & Jerry 3 that exclusively contains Jerry's levels from the original game. All cutscenes from the original game are removed. Credited to Power Joy Ltd. Features another game variation, Primitive Woman, built into its code (the games are altered between two bytes in the footer area).
The Primitive Man character would later be featured in a series of Olympic split-game variants.
Primitive Woman (Power Joy)[]
Hack of Tom & Jerry 3 that exclusively contains Tom's levels from the original game. Credited to Power Joy Ltd. Built off of the same file as Primitive Man. This hack features a glitch where after getting a game over, the game switches to Primitive Man.
Primitive/原始人 (Nanjing)[]
Primitive (原始人) is a standalone Famicom cartridge version of Primitive Man released in China by Shenzhen Nanjing. Compared to the original plug and play version, Primitive adds cutscenes that are shown before each level.
Primitive II/原始人II (Nanjing)[]
Primitive II (原始人II) is a standalone Famicom cartridge version of Primitive Woman released in China by Shenzhen Nanjing. Like Primitive, the standalone cartridge version of Primitive Man released by the same company, Primitive II adds cutscenes that are shown before each level.
Others[]
F-1 Race[]
Ardent Rally (VT03)[]
Motor Race (VT03)[]
Super F1 Race (Shenzhen Niutai, VT03)[]
Super Motor Race (Shenzhen Niutai, VT03)[]
Super Rally (Shenzhen Niutai, VT03)[]
Mario Kart[]
Title screen.
Not to be confused with Mario Cart, an unlicensed Game Boy Advance game developed by Sintax. A Mario Kart-themed hack likely commissioned for the Family Karaoto system. Despite being the only known 8-bit F-1 Race hack by Nice Code, it was produced considerably after the VT03 versions.
Mario Kart changes F-1 Race's three courses to the Mushroom (spelled in-game as "MUSHRQOM"), Flower, and Lightning Cups, and allows the player to play as either Mario or Luigi. The race track layouts are entirely different, and all of the opponents resemble Mario and Luigi.
The graphics are primarily adapted from Mario Kart: Super Circuit, with the character sprites and track details coming from that game. Each "cup" uses graphics from the first track in the equivalent Super Circuit cup: the Mushroom Cup from Peach Circuit, the Flower Cup from Mario Circuit, and the Lightning Cup from Luigi Circuit. The title screen, on the other hand, adapts its graphics from the main promotional artwork for Mario Kart 7[2], dating this hack to 2011 at the earliest.
Compared to F-1 Race, Mario Kart is overall laggier and more sluggish. None of the original music from F-1 Race remains; the only music audible is custom music composed by Nice Code in their own distinctive style.
Pokémon 4-in-1[]
Pet 4-in-1[]
Menu screen.
A basic hack of Pokémon 4-in-1, an unlicensed game developed by Mars Production. All instances of Pikachu are modified to make him resemble a cat (or a bear for the main menu graphic), among other cosmetic changes; the Pac-Man game is renamed to "Bean". The controls in "Pet Dance" are altered compared to the original game's Picadance, now being controlled solely with the d-pad (making some moves impossible to perform on a standard Famicom/NES controller).
The game is only known to appear on the Power Joy Supermax 30-in-1, separated into two of its included games (Pet Dance and Pet Slot) in the multicart menu. The other two games (Pet Click and Bean), despite not being linked, can be accessed by pressing "B" on Pet Dance's title screen. Pet Slot has its code area adjusted to not allow backing out to the menu, despite that the other games do not have this function altered.
