can anyone tell me if i can make a homemade super game boy cart or mod my snes to accept gameboy games, i have an original game boy and a gbc i can use to do this if it is possible

just get an actual super game boy. making one yourself would be too pricey and difficult. If you want gbc games, just get a gamecube and game boy player.

A super gameboy is like $5+shipping on ebay. Buy one.
