I want to play Homeworld Cataclysm. Game has  3dfxOpenGL mode but it doesnt work. It wont work under Win NT as writen in the manual. I am using Win XP.  Are there any tools that can make Cataclysm use my Voodoo2?

yes.first,make sure you use the latest Fastvoodoo2 driver.then,try the opengl icd version 1.0.0.0505 from here: http://www.falconfly.de/opengl.htm ,unpack it to your cataclysm folder,and rename the file to opengl32.dll (make sure your system shows hidden files and file extensions).ingame,select opengl as your renderer.this should work.if not,use mesafx,the same way as the icd..you can get mesafx here: https://www.3dfxzone.it/dir/3dfx/mesafx/archive/
