So I bought Interstate 76' here at GOG. Didn't work as intended out of the box, and had to try a array of different fixes to get it working on my Windows 11 machine. Turned out it wasn't too difficult but it was incredibly frustrating finding the fix that worked for me. For anyone who is curious, I referenced a YouTube video to get it working: https://youtu.be/XWykWZh23js. It utilizes a dgvoodoo2 as well as an FPS capped executable that can be found on some git page. The music didn't initially work, but I managed to solve that by creating a virtual audio disc image using the included mp3 files and mounting that on daemon tools lite.

On another more important note, I was wondering if there is any reason why GOG does not simply include images of the original i76 discs? I notice that the GOG files are so modified that it simply doesn't even work on Windows 98, which is more or less the game's native environment. Having images of the original discs would be very useful, especially since there are emulators these days that can install and run Windows 95/98, which would allow this game to run comfortably without having to find some arcane fix every time a new windows version rolls out.

I notice that GOG provides such images for games like Quake 1. Anyways, just throwing that out there.

Licensing. With games like Interstate, your best bet might be something akin to a Nglide wrapper, or better yet, do what I do and laugh while running it as natively as it can go in WINE.

How did you get it set up on wine?

I tried this on a Linux machine and while the music and game worked, the cutscenes did not, and there were some weird window resizing issues. I believe I used a 32-bit prefix with Windows 98 to get it going.

I installed it previously on an external drive and pointed Lutris at it. I note that while I can't get I76 to work, Nitro is working.

on my windows 11 it works fine with few steps:

1. install the gog version

2. In the i76 installation folder, delete glide.dll, glide2x.dll, glide2x.ovl, and OpenGlid.ini

3. download the latest dgvoodoo
https://github.com/dege-diosg/dgVoodoo2/releases

4. Copy to the i76 installation filder the following from the dgVoodoo zip:
dgVoodoo.conf
dgVoodooCpl.exe
MS/ x86/ everything
3Dfx/x86/ everything apart from Napalm folder

5. download the winmm drivers
https://github.com/dippy-dipper/ogg-winmm

6. Copy in the i76 installation folder from the ogg-winmm_rev3 everything

7. In the music folder, create music files to ogg format with names track02.ogg, track03.ogg etc
Either convert the mp3s in the music folder online (https://convertio.co/mp3-ogg/) or find the CDs online and convert them from the audio CD 2.

Let me know how it works.

Also, I did manage to get it working on Linux via lutris but cannot remember exactl;y all the steps.

edit: for voodo, choose a 4:3 resolution, eg I have 1280x1024, and a simple voodoo with 2mb only. Then open the ini file and find this
FPSLimit = 0
put it to 30 or 20 to stop the AI going crazy

Pamphagus -- thank you for the simple guide. I got the game to play -- visually it looks great. I cannot get the music to work at all though. I get the music for the 2 intro scenes when the game loads, but no music on the main menu (i think this was track13, but it's been many years!) nor in the game. Sound effects and Voices play fine.

I reinstalled it and only added dgvoodoo (left the GOG music folder and files alone) and now I have the CD audio tracks working! The tracks do loop, but that's fine.

To anyone else following this, you need to make a shortcut to i76.exe and add " -glide" to the end of the Target like so:
"D:\GOG Galaxy\Games\Interstate 76\i76.exe" -glide

Also, in dgVoodoo, choose 2MB RAM and 2048KB TMU (single TMU Voodoo Graphics or Voodoo Rush). I'm using FPSLimit = 20 from what I saw on other threads regarding the flamethrower and the sound of the machine gun.

I do have an issue with the "are you sure you want to leave the Salvage parts" or whatever it says exactly - I had no mouse cursor and the keys didn't seem to highlight YES or NO. Not sure how to get past this.

This worked for the music, thanks.
