Developer: Champ Games
Champ Games is the homebrew label of John W. Champeau. In 2006 it released Lady Bug, a conversion of Universal’s 1981 arcade maze game, written from scratch for the Atari 2600. A 1982 Coleco catalogue had listed a 2600 version, but it never appeared. You steer a ladybird through a garden maze and swing its gates to shut out the insects. The site also has the PAL60 build.
