all games designed for the voodoo2 used windows
if your are talking dos games designed for the voodoo1 running on a voodoo2 then most should work
some will need the v1 enviroment variables in autoexec.bat

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

OK. What do i need please ?

So i need to copy paste these to Autoexec.bat ?

Cause i'm trying to run Screamer 2 and Screamer Rally with no luck so far.

Though with Canopus Pure 3D they work.

what games do you want to play ?
and you do have a voodoo 2 - yes ?

edit:
screamer 2 + screamer rally are windows games

edit:
you say screamer 2 + rally dont work then you say they do
what is it ?

edit 2: a canopus 3d is a voodoo1 not voodoo2

Yup. From Dos with Canopus they play fine. Both of them. Now any chance to play them from DOS with Voodoo 2 (Creative or 3D Prophet II) ?

are they running in 3dfx mode in dos ?
i am pretty sure they used windows glide not dos glide

edit: you are right its a dos game

get the voodoo2 patch fro screamer rally
http://dlh.net/cgi-bin/dlp.cgi?lang=eng&sys=p … dfx2.zip&ref=ps

for screamer 2 try this

create a file called runme.bat

paste the following into it :

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=0x0set
SST_TMUMEM_SIZE=2
SET SST_SCREENREFRESH=60
SET SSTV2_FASTMEM=1
SET SSTV2_FASTPCIRD=1
SET FX_GLIDE_ALLOC_COLOR=3
pause
s2

(i am assuming s2.exe is the sreamer 2 3dfx program if not change the s2 line to whatever the screamer 2 program is called)

then run the game by typing in runme

@Davros many many thanks for your time. I will try this and i will update the post.

This really helped me sort my Screamer 2 out FinallY!

After installing the game on my WIN98 machine, software mode played fine in 320x240 and 640x480, but the 3DFX patch just would not work. Hanged on a black screen straight away and I had to hard reset. I tried the batch file written above and got an error message (better than black screen) saying triple buffer command fail. I then searched google and found that the Voodoo 2 cards had trouble with the 3Dfx patch with the 280kb S2_3dfx.exe, and that there was one which was 1.12mb containing S23dfx.exe (no underscore). After an hour I found it and it worked, but the colours were washed out and pinkish and the game played at a very slow rate.

Using the batch file above WITH the S23dfx.exe works PERFECTLY. And I'm very, very happy.

Thanks a million. 🤣

Please jot down a living link to that patch here, it is nowhere to be found on the internet anymore...
THANKS!

Yes it is! I found it! Took me about 2 hours though.

I can't remember where I got it exactly now because I visited SO many sites. PM me and I will send it to you. I will look into posting it online somewhere that will host it for free, but I don't know where to look.

Also I just bought Screamer Rally original from EBAY and apparently, the 1MB patch I have which works (the S23dfx.exe) came on the Screamer Rally CD.

So yeah. PM me.

I have screamer rally as well
so if anyone needs the patch

Thanks Iris and Davros,

in the meantime I have also found a SC Rally CD.
The SC 2 Voodoo 2 patch was available on an Italian site (no wonder, the largest pro 3dfx community was/is Italian). Still looking for that link to make it public.

😉

why not submit it to the patches scrolls

Good idea, I have sent them a request. Hopefully they will upload it.

The solutions given in this thread are spot on if you want to run these two games on a retro computer. Both games ran fine on my Compaq (200mhz mmx, 80 mb SDRAM, Voodoo 2 SLI), though Screamer 2 always crashed when I tried to exit the game. Though it took some trial and error to get it working. Thank god I found this thread!

I had no problem finding the s23fx.exe patch for Screamer 2 on Google, but I'm putting it up here as an attachment.

Want to add that if I tried to run Screamer 2 and Screamer Rally through Windows 98 I got a crash. I had to restart or boot into native MS-DOS. Since the game is abandonware I first tried the cracked/DOSBox version, but this didn't work for both games when it came to the 3dfx versions. After some searching I managed to get hold of the ISO files. They work perfectly and also the CD audio music is nice.

Woah, screamer 2 is certainly not abandonware, the developers still exist as do the publisher
