Ok...I wanted to play this classic the other day, but I am having some problems. I am in charge of a lab that has 20 stock 733g4s. All of them have 9.2.2. When I start up D3, it does the Tantrum cinematic, but then the screen goes black and nothing happens. The ONLY way to get out of it is to restart.

Any help would be greatly appreciated.

Descent 3 was always kind of buggy for me, and seemed rather sensitive to changes in my system (why I do not know) all I can suggest is doing a clan install.
You could also make a Game extension set in the extensions manager, with the basics extensions (the Mac's name for Drivers) to get the game to play which will be (all game sprockets, OpenGL, QD3D, Quicktime, CD/DVD reader, USB and HID extensions, and anything to do with Opentransport).
The game is a little old (but still looks and plays great) so it might be incompatible with 9.2.2, I've emailed graphsim (the Mac Deveoper/porter of the gsme I believe )about probs I had with the game in past, but with no success, but I'd give them a try if nothing else works.
