if you google "Duke 3D high res download" you can find a high res [better than before, by a lot] port of Duke 3D. it requires you having the .grp files, but it doesnt have any xp problems
p.s. both blood and duke 3D [before i upgraded

] ran fine in 800 x 600, though duke 3d didnt work after i followed the steps for 3 days, then ran fine for no reason
any questions, like you cant find it or whatever, email >
