Assuming you don't have a 3dfx card, try going into the TEN
File-Preferences-Games menu page, and browse to select NROS as the enabler
instead of NROS3DFX. If you do have a 3dfx card, you can run with the
3dfx enabler (NROS3DFX), but you'll need to copy the glide DLL into the
enabler directory to do so. I think that requires glide2.dll (not sure if
that's the correct name for the DLL though).
