Ok, so this is something I've been wanting to do for a long time. I've wanted to make one machine that did it all. Does anyone know of a way that you could put the insides of an Xbox 360, PS3 and computer into one case and have them all read CD's from the same optical drive?
I don't think it wouldn't be a hardware thing, you'd have to do it with lots of software and converters and emulators, generally i think it'd be far too much of a pain to be worth it you might as well just get a PC controller hook up a gaming pc to an HD TV and run the PC versions of those games...
The disks for both systems I think are standard DVD's so a normal DVD drive should be able to read it you just need a conversion program to process what it reads and an emulator to run the information. So my point is even though it'd be a pain, the easiest way I see it is to do it via software instead of shredding a 360 and a PS3 up to try an accomplish this with hardware.
or you could just build a case that holds both so i'd look like one machine with two drives, i guess that's just a cosmetic solution though.
