I just installed an old favourite Q1 ,and it went on fine. When I go to the install directory and click on the Quake.exe I just got a blink of a dos screen then nothing. Is Quake1 XP compatibile? Has any one tried the D3D Quake1 patch? To use this patch do you need to upgrade Quake to 1.08 as well as GL quake first,or is it an all in one patch?
