Publisher: Coleco

Coleco made its own ColecoVision console, and it also published games for the Atari 2600. It held home rights to a long list of arcade games, Nintendo’s Donkey Kong among them, and many of its 2600 cartridges were versions of games it also released for the ColecoVision. Much of the 2600 work was done by outside programmers and studios: Garry Kitchen made Donkey Kong, and companies such as Individeo, Wickstead Design, Woodside Design Associates and CommaVid handled other conversions. By late 1984 Coleco had stopped making 2600 games, and Atari later reissued several of its cartridges under its own label.
The site has 14 Coleco games. Some places to start:

Donkey Kong (1982): two of the arcade’s screens, with the barrel-jumping intact.
Donkey Kong Junior (1983): play Kong’s son and climb vines to free his father.
Venture: explore a dungeon of treasure rooms, converted for Coleco by CommaVid.
Smurf: Rescue in Gargamel’s Castle (1983): a side-scrolling jumping game that won an Arkie Award for its audiovisual effects.
Mr. Do! (1983): dig tunnels, pick cherries and drop apples on your pursuers.
Cabbage Patch Kids: Adventures in the Park: a finished but unreleased 1984 game, found on chips at a flea market in 2008.
