BootlegGames Wiki

This page details a specific developer for Famiclone plug & play devices, of which the actual development company's name is unknown. The company is known to have some sort of connection to JungleTac, and is even credited as simply "JungleTac" in some releases.


The unknown company is known to have produced numerous titles for UM6578 and VTxx-based Famiclones. The most clear indication of their games is the sound design. Virtually all games use the same sound effects; some of the games use no background music at all, though the ones that do feature a very unique music style (similar to that of many Dance Dance Revolution NES clones).

The company has some sort of connection to JungleTac; several titles are even modified versions of JungleTac's older games and hacks. Despite this, the general attributes of the unknown developer do not match that of JungleTac. While the two companies clearly have some sort of connection, it appears as though the developer is not JungleTac itself.

Many of the unknown company's games were initially produced for various Techno Source plug & plays; several of these games were later republished by Waixing under different titles. It appears that Waixing may have purchased the full copyrights to the games, as Waixing produced new iterations of the titles themselves (e.g. enhanced VT168 ports); while when Waixing re-copyrighted outsourced games from other companies, this seemingly only applied to VT02/03 versions.


Intellivision and Coleco ports[]

The unknown company produced several games - running on NES/Famicom hardware - for Intellivision and Coleco-branded plug & plays, which were published by Techno Source. The Intellivision games are ports of various titles from the system; these are not to be confused with the Intellivision ports produced by Nice Code Software, which were used on earlier Techno Source releases. The Coleco games, rather than being ColecoVision ports, are based on the "Head-to-Head" handheld LCD sports games from the late 1970s; ironically, some of these games are also featured on the Intellivision systems. Oddly, original games not based on actual INTV/Coleco properties are also included in both game sets; several of these are clones of other games from the 80s.

While Nice Code's Intellivision (and Atari) ports are still occasionally distrubuted on plug & play systems today, the unknown company's licensed ports were only used on four consoles total (the Intellivision 2nd Edition, Intellivision X2, and separate 6 and 12-game variants of the Coleco Head-to-Head system).

Coleco games[]

  • Baseball - also used on the Intellivision X2 with modified graphics
  • Basketball
  • Boxing - uses sound effects from Punch-Out!! and Super Mario Bros.
  • Car Racing - a generic racing game; uses sound effects from F-1 Race
  • Deep Sea Madness - a clone of Space Invaders
  • Football - also used on the Intellivision X2 with modified graphics
  • Hockey - also used on the Intellivision X2 with modified graphics
  • Kung Fu Fly Catcher - an original game where, when a fly appears on the screen, the player must press the button as fast as possible; this will catch the fly in a pair of chopsticks, and the player is given a score based on their "reaction time". Uses sound effects from Galaxian
  • Racquetball - an original game which is effectively Pong played on one side; with the opposite end being a solid wall.
  • Sea Defender - a clone of Missile Command
  • Soccer
  • Wallbreaker - a generic Breakout clone; uses sound effects from Arkanoid and Super Mario Bros.

Intellivision games[]

  • Crown of Kings - port of Advanced Dungeons and Dragons: Cloudy Mountain
  • Deadly Discs - port of Tron: Deadly Discs
  • Frog Bog
  • Long Drive Golf - An original game where the player must hit their golf ball a further distance than the opponent. The game is copyrighted directly to Techno Source rather than Intellivision on the title screen.
  • Maze Shoot - port of a minigame from Sharp Shot
  • Night Stalker
  • Pinball
  • Soccer
  • Space Armada
  • Space Gunner - port of a minigame from Sharp Shot
  • Tennis

TV Play Power VT02 games[]

A generic set of ten original games, of particularly low quality; all of them state "© JungleTac, 2003" on the title screen. The games are known to appear on several obscure releases, including the Techno Source "TV Play Power" system and the Handymax KT-0001 Famicom multicart. However, their most common form of distribution was by Waixing, who republished some of the games with altered titles.

  • Balloon Pop - Shoot the oncoming balloons before they reach the bottom of the screen. Released by Waixing as Shooting Ballons.
  • Boxing/Knockdown - A very slow boxing game. Released by Waixing as Boxing Wrestle.
  • Drop Em - A monkey must drop rocks onto mice before they get inside the burrows. Released by Waixing as Hitting Mices.
  • Get Em/Shoot Down - A cannon must be aimed at oncoming enemies. Extensively hacked and released by Waixing as Super Ward (VT03).
  • Highway - Top-down game similar to Frogger.
  • Hungry Worm - A snake game. Released by Waixing as Edacity Snakes.
  • Paddle Fun/Ping Pong - A Pong clone. Released by Waixing as Table Tennis. The common Waixing release alters some sprites, though a rare alternate version retains the original "Play Power" graphics in-game.
  • Raceway - A generic racing game.
  • Snow Boarding/Skate World - Hack of the aforementioned Raceway.
  • Submarine/Submarine Adv. - A basic shooting game.

The "Timemax" library - a plug & play game set formed in 2022 - reportedly features two additional games: Rocket Cart, which was reworked into Highway Racing I (?), and Present, which was reworked into Xmas Gift. This game set also includes Ping Pong.

Waixing-published VT02 games[]

Many of Waixing's further VT02 titles - of which the origin is unclear - appear to also be developed by the unknown company; this is evident by various aspects of the code itself. It is unknown if non-Waixing versions of these games exist.

  • Desert Gunman - Hack of Wild Gunman.
  • Diamond - An Arkanoid clone, but different to Nice Code's identically-titled clone; there are no diamonds in this version, the physics are also more consistent but it only has one level.
  • Explorer - A clone (or possibly a somewhat advanced hack) of Galaxian.
  • Fireman - A clone of Flying Hero with only one level.
  • Guard Farm - Hack of Duck Hunt.
  • Highway Racing I - A clone of Road Fighter.
  • Lawn Purge - The player must mow the entire lawn before the timer runs out. The game is very similar to JungleTac's Grass Cutter, with nearly identical level layouts.
  • Overspeed Racing - Smilar to Highway Racing I, but in a pseudo-3D perspective.
  • Police Skill - Hack of Hogan's Alley.
  • Plumber - An uncommon clone of Mario Bros.; the title screen features modified artwork from Super Mario 64 with Mario's head replaced with a generic anime boy.
  • Tank - Clone of Battle City.
  • Xmas Gift - Clone of Nice Code's Mad Xmas, coded from scratch.
  • Square - A clone of Tengen's version of Tetris.

UM6578 games[]

Several UM6578 games were produced by the unknown company; these titles appear on some uncommon plug & play systems, such as the "Wikid Joystick 14-in-1" and the "Console TV Challenge". The majority of these games are modified from JungleTac UM6578 releases; for example, an Arkanoid hack titled Block Shock was re-hacked as "Rescue" (effectively making a hack of a hack).

Original or JungleTac-based games[]

  • 99 Layers - Clone of NS-Shaft.
  • Alien Attack - Hack of JungleTac's Aero Engine.
  • Bee's Attack - A shooting game similar to Space Invaders; the enemy designs appear to be loosely based on Galaga. The Game Over screen uses the font of the Sega logo.
  • Future Soldier - The player must rescue tied-up people while shooting at enemies from a top-down perspective.
  • Pyramid Secret - Clone of the shareware PC game Zeek the Geek, with original graphics.
  • Shark - a game similar to Shark! Shark! for the Intellivision, where the player's fish must eat other fish (without being eaten themselves).
  • Space War - Hack of JungleTac's Star Ally, which in itself is a clone of Recca.
  • Air Force, Frontier Fire, Hurricane - Various games based on JungleTac's top-down shooting game engine (as used in numerous standard JungleTac games like Bolt Fighter).

Hacks of Famicom/NES games[]

Games based on preexisting JungleTac hacks reuse some graphic assets, while redoing others; the music and sound effects are often extensively altered. For additional information on the "original" hack variants, see the JungleTac page's "Hacks" section.

Original Game Hack Name(s) Notes
Arkanoid Rescue Based on a preexisting JungleTac hack titled Block Shock.
Balloon Fight Balloon War Based on a preexisting JungleTac hack titled Balloon Boy 2. The Balloon Trip mode is removed.
Bump 'n' Jump Water Bike Based on a preexisting JungleTac hack titled Jump Car.
Circus Charlie Clown Uses a sprite of Mr. Do from Neo Mr. Do! on the title screen.
Duck Hunt Super Hunter
F-1 Race Mega Race Based on a preexisting JungleTac hack titled Race One. The original version takes place in space, while the affiliate's version instead changes the background to Mount Rushmore.
Hogan's Alley Target
Lode Runner Magician
Lunar Ball Table Ball
Magic Jewelry Fruit Master Uses a modified sprite of Pac-Man from the Pac-Man 2: The New Adventures intro. It is unclear if this is based on JungleTac's preexisting Jewel Master hack or not.
Pinball Pin Ball Themed after a carnival tent. It was later re-hacked into the VT03-based Radium Star, which is seen on some Double Dance Mania consoles.
Road Fighter Road Hero Based on a preexisting JungleTac hack titled GP Race.
Sky Destroyer High Tide
Slalom Alps Ski
Tennis Tennis Mario is intact, but his hat is removed.
Wild Gunman Quick Shoot

An uncommon console called the "Solar Games Super 7 in 1" features VT02 hacks based on the JungleTac/unknown affiliate's UM6578 library, but are closer visually to Inventor ROM hacks of the same games.[1]

VT03 Dance Dance Revolution games[]

While not believed to have produced all DDR clones, the unknown JungleTac affiliate seemingly developed the software to three dedicated Dance Dance Revolution plug & plays. All of them are based on VT03 architecture, and two of them are officially licensed by Konami.

  • Dance Dance Revolution Disney Mix - Licensed port of the PS1 release to VT03 hardware. Features songs such as the "Mickey Mouse March" and "Supercalifragilisticexpialidocious".
  • Dance Dance Revolution: Strawberry Shortcake - An original DDR game, not based on a preexisting Konami release.
  • Double Dance Mania: Technolight Edition - A large, two-player dance mat. Only features three generic songs: Firestorm, Riptide and Vortex. Minigames include 25 Hurdle Challenge (clone of a Track & Field event), Asteroid Racers (an asteroid-dodging game), Duck & Dodge (a Whac-A-Mole game), Hip-Hop Scotch (follow the on-screen moves), Snowstorm (a Breakout-like game), and Radium Star (a hack of Pinball).
    • Radium Star is built off of the UM6578 Pinball hack, as evidenced by it featuring near-identical graphics in the bonus rounds; however, the rest of its graphics are largely unique.
    • The "original" version of Double Dance Mania appears to include Radium Star, but otherwise features different software that likely comes from other developers (including the uncommon VT02 games Echo Chamber and Trounce).


  • It is possible that the unknown company produced the bootleg "Gamezone II" arcade ports; which consist of NES conversions of Frogger, Scramble, Missile Command, Asteroids, and Moon Cresta. Due to the limited information known about these ports, however, this cannot be fully confirmed.
    • There are a handful of similarities in coding between the Gamezone II ports and other games from the JungleTac affiliate. For instance, the hopping sound in Frogger is the same as the paddle-hitting sound in the "Rescue" Arkanoid hack; which is otherwise not a common and/or recurring NES sound.
  • The Techno Source Coleco systems' basis on using the "Head-to-Head" games - rather than the more popular ColecoVision titles - was likely due to Coleco (under River West Brands' ownership) not actually owning many, if any, of the ColecoVision game IP rights. Ironically, many later 2010s Coleco systems (particularly from AtGames) appear to just use the ColecoVision library without license; including titles that Coleco would almost certainly have no legal ownership of.
  • There is a set of three Coleco-branded 10-in-1 handheld consoles released around the same time as the "Head-to-Head" plug & plays. The games on these systems resemble the JungleTac VT09 library, but are custom coded versions running on unknown hardware; it is possible the game software for these units was also produced by the unknown JungleTac affiliate.
  • For unknown reasons, most (if not all) of the unknown company's VT02 games use a CNROM/"mapper 3"-like code format, which is not generally used by other plug & play manufacturers (in which the games are typically designed as NROM or MMC3). The CNROM-like coding is generally only used for the title screen graphics.
