The game just installed fine and the patch by Knightmare (KMQuake2) is also working fine but there is a problem.
When set to resolutions higher than 800x600, the screen stays at the lower left corner of the screen instead of proper widescreen (the patch is working but not really) and i don't think it is a problem in the patch since the screen just doesn't fit well in 1024x768, so i think this is a problem in the game.
