Hello Kodiak,
You can run HK on your system with the Voodoo2 Card. You might need the Korea 1.02 patch. Im not sure, been a long time. You will only be able to run HK in 800x600 in Voodoo 3dfx.

If you buy PSF same as HK. You wont have to install your voodoo 2 card and you will be able to run it in OpenGL mode at 1024x768 with full anti-asailing. Which looks sweet!

Mark, Ive tried many glide wrappers only to find none work but that was a few years back. Some of the guys are doing well with them with Red Baron III and Janes F-15.

Cheers !
Pretzel~
