This is sort of covered in the workaround thread but I will repost here.
=====================
Basic runthough of what I did.
Install the game (you may have texture acid trip color problem)
Write a .bat file to end explorer and launch the game(s) You will need one for I76 and Nitro76 put one in each of the games directories. Just make a notepad file paste the following code in and change the extension to XXXX.bat
This is the I76 code.
---------------------------------------------------
taskkill /f /IM explorer.exe
start /w i76.exe -glide
pause
start explorer.exe
---------------------------------------------------
This is the Nitro code.
---------------------------------------------------
taskkill /f /IM explorer.exe
start /w nitro.exe -glide
pause
start explorer.exe
---------------------------------------------------
The game should now load with correct colors and be using the -Glide renderer
Download the DGVoodoo program here
http://www.bunnzy.org/files/extras/apps/dgVoodoo1.50Beta2.zip and extracted it to the I76 AND Nitro directories. It may Overwrite several files. Run DGV, set it all up (choose your Resolution). Clicked OK.
Run the game..
It may have a light blue line around the screen which I can live with..
HOWEVER, all the textures may start going berserk after a minute. On mine explosions turned into giant tires.. My cars tires turned into fire (oh yeah). Brake lights were something wrong and small.
Other then that she looks damn good.
