Sharedata well known for their low cost TV show games in the mid to late 1980s for both the C64 and PC. Some of the Commodore 64 games they released were Family Feud, Jeopardy, Wheel of Fortune, and Wipe Out. For PC Avoid the Noid, Starquake and Family Feud. Sharedata started American Game Cartridge Inc (AGCI) in 1989 their first unlicensed NES game was Chiller programmed by Richard Frick. Chiller is a zapper game where you shoot zombies and other dead things overall not a bad game then came Shockwave and Death Race, Shockwave is a bolder dash type puzzle game and Death Race a Racing/Shooting game.

After this AGCI went bust around 1992 their second zapper game Crossbow and Wally Bear No Gang both went unreleased. Not long after the death of AGCI American Video Entertainment (A.V.E) released Wally Bear No Gang but unfortunately Crossbow never saw the light of day due to the fact that it was unfinished when AGCI went bust and either they did not give the source code to A.V.E or they did but A.V.E chose not to finish and release it.

Recently two very interesting AGCI cartridges have been found by collectors Wally Bear No Gang! owned by TheRedEye in a AGCI case with a never before seen label the case contains one EPROM the game itself is the same as the A.V.E release. The second being a Chiller in a Color Dreams case with a ShareData label, the PCB is also by Color Dreams. I guess ACGI bought enough cases and PCB's from Color Dreams to do a trial run but then went ahead and got their own cases and PCB's made.
