I'm not a PS3 genius by any means, but here is my logic.People are loading PC OS's onto the PS3.You can play PS2 Games on a PC.What is in the software of the PS3 that the 20gb works, 40gb doesnt, 60gb does,at least if we understand why the 40gb doesnt play ps2 games, maybe we can work towards a fix. Why does the 60gb play ps2 games? software?
