Hey again Folks, Well, just over the March break I finally figured out the interface required to connect a 1MegaByte Flash Memory chip to the Game Gear. I used the SEGA 315-5912 Mapper IC that is found in Game Gear Games like "Garfield" or "Sonic Blast". So a 1 MegaByte Flash cartridge for the SEGA ...
