This guy is claiming to have an XBox with emulated games of a pretty large selection of retro systems. But to claim that he has EVERY game made for Amiga, NES, Sega, Intellivision, etc. on a 250 gig HD makes me rather doubtful.
Actually not that dubious. I think all the Amiga ADFs fit in about 20-30GB. Intellivision wont take much, probably fit on a CD with space to spare for 2600, Coleco and others.
