sounds like BS to me.. "into the warez scene" doesn't explain how he would be the only person to have this emulator.. If it hit the warez scene, everyone would have it by now..
if your friend was some great coder who claimed to have WRITTEN a working xbox emu, then maybe. But he is claiming he got it by being 'into the warez scene'? If that was true, everyone would have it.. A 2 meg xbox emu would be on every pub from here to timbucktoo..
It wouldnt be a commercial product, a la bleem, since PC DVD drives cant read originals. It would have to be a homebrewed product, and as such, probably wouldnt have jack-shit to do with the 'warez' scene, it would be posted on any old emulation site.
Is there some warez group that I dont know about that only releases titles for this guy?
PS. I do believe playing xbox titles on a PC is possible, and it wouldnt even really be an 'emulator'.. A PC could pretty much run the code natively, you'd only need to emulate the custom features of the MCPX..
