Only if the games have been "ported" over to the system. A few have been, like the old FPS games, like Doom/Doom2/Quake/Quake2, etc. You can't just put a PC game in/on an Xbox and expect it to play.
It cannot play the PC Game Disc itself. You have to transfer the game onto the xbox hard drive and have it emmulatr the game.
There are DOS emulators, to play old DOS games on Xbox...but I'm not sure about compatability/speeds, etc.
pre modded actually means already modded if you are buying from a website... that's how i got my first modded xbox before i knew how to solder
Sorry,the last person I talked to on a forum used the term [bold]pre[/bold] as in 'before' modded. The prefix has more than one meaning in this sentence.
Usually, the term 'premodded" means the system was modded for you. Modded pre-sale. But I can see where you could take it the wrong way.
Unless you're talking about one of those xboxes you can buy that has the 128mb ram etc (which seems to be only of real benefit in graphic intensive multiplayer games), a premodded xbox is just an xbox you buy already modded. There aren't any pc emulators for the xbox, as Atari born mentioned there is the dos emulator, which no doubt would run the old scumm games such as monkey island etc (made popular my lucas arts), but i don't know that for sure. There isn't even a commercially working ps2 emulator for pc yet, so I doubt a pc emulator would ever be feasible on xbox1, though perhaps a direct x8 emulator for xbox could be possible, but that would mean a lot of work no doubt, lol. Peace Out
128MB ram upgrade will not improve your games,since they are flagged to use 64MB....the only thing that the upgrade will benefit you with is 'some' emulators that are coming out and running Linux. Which is probably the only way (other than DOS) where you can run pc games. If you run a small (and I mean small) Linux,you can emulate Win98 and run small pc games. It will be hella choppy though.
