Edit: If it helps, my game is Carmageddon: Max Pack.
The programs didn't install anything like VOODO2C.EXE. Do I have to use 3DfxCarm.EXE as a standalone executable to install it, and not use it in Glidos at first? Because If I double click on 3DfxCarm.EXE, a windows pops up and says:
16 bit MS-DOS Subsystem
C:\intrplay\Carma\3DfxCarm.exe
This system does not support fullscreen mode. Choose 'Close' to terminate the application.
If I use 3DfxCarm.EXE as the Glidos executable, it says "Not an LE Format File". If I try the carv24rw.zip version of CARMAV.EXE and the supporting files, The same white/black screen still appears, and nothing happens.
