Hello,
I have been trying to run Tomb Raider (the voodoo patch obtained from the Unfinished Business CD) under the dos of win95 and I have this error :

Has anyone experienced this and what would be the cause?

You might want to take a look at this page:

Some of the information is Windows-oriented, but much of it is relevant to Voodoo2s under DOS as well.

I have been searching for ages how to make Tomb Raider 1 work under dos 6.22 on a new PC.

What do you mean with "new PC"? If you mean a current, quite fast PC, then why don't you just use DOSBox to play TR? I've been playing TR with ykhwong's DOSBox build, which does support GLIDE emulation. The game runs perfectly well, and looks amazing.

It's also possible to play TR with the VDMSound/GLIDE wrapper combination, but i never really got that working, so i sticked to the DOSBox solution.

What also might be interesting for you is the fact that i had to use the Voodoo Rush upgrade, not the 3DFX one, to make acceleration work. The 3DFX update seems to have the glide2x.ovl (i think that's what it is called) included in the .exe, where the Rush upgrade uses an external file.

"but apparently it does't search for the glide2x.ovl "

try putting it in the game folder

OK, in fact after a while, I have installed Tomb Raider on an old PC (PentiumII 166MHz), plugged the voodoo1 card and all is working perfectly, the colours are beautiful. I have just put the glide2x.ovl in the tombraid folder and the game launches without any problem.
