M.C. Kids has been hacked.
(Note: include some of the utilities for M.C. Kids here)
A prime example of an M.C. Kids ROM hack is Dalton McGuinty's Kids' Computer Game. Created during the 2003 Ontario provincial election, DMKCG taught kids about the values of eating right and exercising. The game can be downloaded here.
The (in)famous Tommy Tallarico was involved in making this video game.
M.C. Kids was produced by Virgin Interactive. You can check out all known Virgin Interactive games at http://www.gamefaqs.com/features/company/1682.html
