Im running it on Win NT, Service Pack 5 at work (LAN game breaks are way too much fun, hehe). My video card is a Matrox G200 and I run in software mode. I have absolutely no problems at all except for the fact that the graphics make me wanna vomit into the disk drive. Software mode sucks ass compared to my GeForce DDR at home. Oh well, I still spank all my co-workers by a LARGE margin. hehehe Poor saps... =0P
