GlideHack performs some special effects with a 3Dfx card by interposing itself between the Glide library and its clients. To install it, simply put GlideHackLib in the extensions folder by dropping it on the system folder. You don't need to restart your Mac. Use the GlideHack Setup application to configure GlideHack's operation.
GlideHack adds the following functions:
• Crash cleanup. If a game that uses the 3Dfx card dies unexpectedly, GlideHack tries to shut things down properly so you get your 2D screen back.
• Screen capture. Ordinary screen dump methods don't work with the 3Dfx screen, and not all games provide this functionality on their own. GlideHack lets you capture both snapshots and movies.
• Various tweaks. This includes things like screen gamma manipulation.
