For the PC you have AdvanceMAME which, with some videocards, can force native resolutions in emulated games. You then hook it up to a TV or an arcade monitor trough RGB. This is great because the games look soo much better in the resolutions the games are made for without the use of streching, filtering and all that nastiness.
I was wondering if this is possible to implement in any of the emulators on xbox since it's already RGB compatible.
Or is it impossible to force the xbox to display lower resolutions?
