Well, we do have a Source for Aleph One, and before i go ahead and start to port it, i don't want to waste porting something that can't be possible. The iPT and iP meet and exceed the System Req's. Surely if the iPT and iP can play Doom or another 2.5D shooter, then surely Marathon. Im just afraid if i go ahead and port it, it might be really unplayable (since the iPT and iP do not a have a GPU.) Would Marathon be Possible?
