Good points. I may need to rethink this. I have this old xbox laying around, and thought it would make an easy conversion. How would you go about making a MAME machine that would fit on an entertainment center? Also, say I wanted to play a 4 player game like TMNT. How would you hook 4 controllers up? Would TMNT, for example, be a CPU intensive game? That's about the era I'd be interested in playing?
