Carmageddon is a graphically violent vehicular combat 1997 PC video game. It was later ported to other platforms, and spawned a series of follow-up titles. It was inspired by the 1975 cult classic movie Death Race 2000. The game was produced by Stainless Games, published by Interplay and SCi.
Fixes many bugs related to running on modern systems, like black screens, crashes, bad performance, no windowed mode, too much FPS, and much more. Adds upscaling, vertical sync, and other useful features.
I don't see any difference other than the ability to toggle the window mode. Do I have to extract it into CARMA/CARMASPLAT, that and then DATA or just Carmageddon1 folder?
What did you expect to happen, exactly? And, are you ultra sure you're using the Windows version of the game, not the DOS one?
