Atari 2600[edit]
Originally promised to appear on the Atari 2600 courtesy of Coleco as stated by a Coleco catalog, the game never saw the light of day. Not even a prototype was ever found. In 2006, John Champeau of CHAMP Games developed this version of the game, to rave reviews. It has since been sold at many classic gaming conventions.
ColecoVision[edit]
Developed by Coleco and published in 1982. Considered extremely accurate. If the player manages to spell out the word "SPECIAL", the player is presented with a vegetable harvest bonus game where the ladybug may consume many bonus vegetables. However, if the player enters the bug box while there is an insect inside it at any time, the player loses a life.
Intellivision[edit]
Developed by Coleco and published in 1983. A little rough, but considered one of the most accurate ports of an arcade game that Coleco ever developed for the Intellivision.
Noteworthy[edit]
Commodore Amiga[edit]
Baby Bug is an unofficial clone developed by 1001 Software Dev, and published by Linel, designed for PAL systems. Released in 1989. It differs from the arcade version because of a different scoring system, but keeps the same maze and gameplay style. Enemies and vegetables use different sprites as well.
TRS-80 Color Computer[edit]
Doodle Bug is a remarkably accurate port of Lady Bug for the TRS-80 Color Computer written by David Crandall in 1982, and published by Computerware.
