I HAVE WRITTEN AN EMULATOR CALLED TGA2 VENUS AND A BETTER ONE CALLER SUPER TGA2
GENS ONLY PLAYS GENESIS ROMS YOU HAVE TO DOWNLOAD BIOS TO PLAY 32x AND SEGA CD
but w/ super tga2 32x and sega cd bios are in the tech games power drive folder of super tga2 it also runs tg roms and it looks like gens when you enter the genesis drive but it isnt gens i just used data from gens to write it
it has kaillera on it as well
