In the past, people had most success with the dgVoodoo glide wrapper. However, with the latest hardware, nGlide is the new champion.
There really isn't any ONE glide wrapper that works for everyone. I think I had most success with the latest 'old' version of dgVoodoo, v1.50 Beta2. I really don't remember. All I know is that the new versions of dgVoodoo, such as v2.32, I could never get to work with LB2.
Glide wrappers are incredibly easy to use, for all intents and purposes, whatever you get in a ZIP archive, you only need TWO files... GLIDE2X.DLL and XXXX.EXE. The DLL file is the actual file the game uses, and the associated EXE file is simply the configurator that allows you to adjust things like screen resolution, etc. Both files can be placed in the game folder so that only that games uses them... this method is known as 'local' installation. A 'global' installation is when you place those files in the '.../Windows/System32' folder so that the PC effectively sees the wrapper as a separate hardware graphics device which can be selected for use by (theoretically) any application or game that uses 3DFX installed on your PC.
