[JMania]

ok, so i was testing some dvd games i have, one of them was Return To Castle Wolfenstein, i installed it and installed the single player resolution patch, but wen i try to open multiplayer it gets me an error, about resulution, and wen i run as admin, it work, but in 640x480 screen, and in my monitor, the borders get choped off in lower resulitions, in 1920x1080 (native) i have no problems, but in 640x480, 800x600, and lower then native it gets chopped in all the places, but if i up the resulution, like from 640x480 to 800x600 to 1280x780 etc, it gets little better, the borders get chopped, but it gets little and little chopped wen i up the resoltion, is there any fix for this?
