Re: playstation and computer
I doubt it. Right now, 128-bit system emulation is crap. They still haven't even gotten Saturn emulation running well. PSX and N64 are great as of now. A bit more tweaking, but otherwise it's good. GBA runs perfect. Newer generation stuff needs more time. That's okay, though. I think it'll be worth the wait.
Just wait until we see PS3 emulated.
