is there a way(driver,some software or what),how to emulate a voodoo1 on voodoo3? Some very old glide games (Incubation) dont recognize voodoo3 as 3dfx card so i need to cheat them so they will "think" there is a voodoo1 instead of voodoo3.Is this possible?

and something simplier:AMD K6-2 333 with voodoo3,what is better for halflife:minigl 1.47 or
wicked 3d 2.31

Tried all of mentioned,didn't work,error message says no voodoo card installed what is obviously not true.
I think there is some difference between Voodoo1(and voodoo2) glide2x.dll and the voodoo3 glide2x.dll that is causing the problem-seems like something is in v1 dll that is mising in v3 dll.I tried to add voodoo 2 glide2x.dll to games directory but error message appiered saying there is no voodoo 2 installed(what is obviously tue).I have no idea what to do next.

Glide 2 and 3 are not compatible with glide 1. Glide 1 consists of 2 DLL's (GLIDE.DLL and SST1INIT.DLL). To run glide 1 applications that require these two DLL's on a Voodoo² you need to setup the variables from the v2auto.inf from the latest Voodoo² driver and restart windows. The Voodoo1 and Voodoo² are both addon boards and the way to program them seems much different to banshee/v3/vsa's. As you can see in the name of the second dll, sst1 was the internal name for the Voodoo1, it is Glide 1 for Voodoo1. The Voodoo² was compatible enough to the Voodoo1 that the Voodoo1 glide.dll still worked. You have to think of Glide as a driver. The glide2x.dll file from the Voodoo² driver is different from the Banshee/V3/VSA driver. So the Problem is that Glide 1 (GLIDE.DLL and SST1INIT) was never ported to the later Voodoo's.

But for some apps it is a good idea to have these two dll's in the systemdir. POD for example only installs the softwaremode version and their worse looking tracks if these DLL's are not found. Of course you can't play the 3dfx Version with these dll's but now you can update the game to the latest 3dfx Version. And this Updated POD runs on GLIDE 2.

P.S.
Does anybody knows if there is an update for PANDEMONIUM. Also this game requires GLIDE 1 for 3D support and thus refuses to run on my V3 (except softwaremode)

Running a batch file to set environment variables works for some Voodoo Graphics games when running them on Voodoo2s.  Try creating a batch file containing the following and running it before you run the game -

set SST_GRXCLK=90
set SST_FT_CLK_DEL=0x4
set SST_TF0_CLK_DEL=0x6
set SST_TF1_CLK_DEL=0x6
set SST_VIN_CLKDEL=0x1
set SST_VOUT_CLKDEL=0x0
set SST_TMUMEM_SIZE=2
