There are 2 different guides? One for 8 bit and one for more advanced stuff? I want one of them but I only wat the lists for nes, snes, sega cd, master system, atari 2600, ps1, n64, saturn, game boy , and game gear. SO I would need to pay $50 for both guides? Thats way too much. Its good info but why couldnt ehy just be in the same book for the $25? Man, now my hopes are gone.
