Correct. Even after getting the game up and running, I came across this phenomenon as I was playing normally. I saw you wrote this on a different thread as well. I included this issue in my reddit guide as well for those who are willing to read the whole guide completely. I had to go through a lot of trial and error so that others don't have to go through what I did.

I wrote a patch for Interstate '76 a while back. Extra steps would be needed to get music working with GOG version though. GOG version comes with a wrapper that is supposed to emulate CD audio - it plays the music from MP3s instead, but the wrapper is poorly written and instead of fixing the wrapper, GOG slapped some ugly hacks in i76.exe to make music somehow work, but still doesn't work properly; same track is not supposed to loop over and over.

Anyway, whoever bothers to learn how to use DxWnd's virtual CD audio feature, will be able to get music working properly the way it was intended with the help of my patch.

It also contains a number of bugfixes and while not perfect, it's still better than unpatched game. Take it or leave it.

You can use DxWnd to get music playback; need to toggle Expert mode in the Options menu and add a profile for the game with the options Virtual CD audio and Emulate CD pause capability enabled on the Sound tab.

Finally, the MP3 files in the Music folder where the game is installed must be named like:

Track02.mp3
Track03.mp3
Track04.mp3
...

Does anyone know how to solve this menu issue? It's very laggy, hovering any menu button is nearly impossible. However, if you manage to start the game in any way, it works fine (Glide + D3D).

Game is playable on Win10 64 Bit so far, using dgvoodoo 2.51.

Yet, after mission 3 the game freezes when I click on "accept" in the menu. I just hear "got it", but nothing happens further.
Reloading doesn't help here.

Seems to be a sound issue?

I tested all compatibility modes, nothing helps here.




I once got this broken menu, too. But now I use the following settings, menu and gameplay is fine so far:

- .exe with -glide
- dgVoodoo 2.51
- overwrite all the old files in the folder
- glide settings: Voodoo Rush, 2MB Memory Size (more causes texture problems), 1920 x 1080, 8x MSAA, Force bilinear filter

Try that out!

But me game still crashes / freezes (see above)

This game is a nightmare!

I can't believe how much time I have sunk into getting this game to work. When I first started it wasn't perfect, but at least I was able to enjoy playing it. Then came Scene 5! No matter what I did I couldn't make the jump at the end. Since then I started looking at videos showing much better graphics and, supposedly, stable game play. I just finished a ridiculously complicated "fix". The graphics look much better but there are graphical glitches where everything suddenly looks like someone vomited colors all over the game world. This was tolerable at this point because if you just hit escape to go to the menu and then go back into the game it goes back to normal. Then I noticed the menu problem. When you go into the menu, especially at the end of a scene, the game locks completely and you can't even use task manager to end task. I have to logout through task manager to close the game. The worst part of all is that I can finally make the jump and complete scene 5, but I can't save it!

Thanks for your reply. With dgVoodoo 2.51 the game does not launch at all: "Failed to initialize 3D hardware acceleration".

But I solved the issue with the menu: Just delete ddraw.dll in the game directory. This apparently is contained in the patch.

Cheers

Furthermore: Would it be possible to create a German version of Interstate '76? I still have the original game discs.

I suppose that the language files are contained in the I76.ZFS

Copying this into the game directory does not work however. The game will not launch. But it could also be related to the fact that I only own the normal edition. I never had the "gold version".

The menu can be translated easily: Just copy DATABASE.MW2 from the game disc and it's in your game disc's language.

Anyone who values their sanity, don't bother with this godforsaken, over-complicated, hilariously un-user friendly pile of shit excuse of a program. I did this down to a T and it still wouldn't play any music, on top of that, in every graphics rendering backend related tab, I could find no way to get the game to launch through DGVoodoo running in Glide, it would boot in fuck ugly software mode every time.
Use _inmm for music playback, it makes the "loop the first track in the music folder over and over after playing the map/mission specific track once" bug return but it's a fuck of a lot better than dealing with DXWnd.
Annnnd now after accidentally clicking the i76.exe in a Previous Versions Windows backup of my i76 folder, inmm now won't play music on the "Tombstone" auto melee map and keeps looking for a "Track 1", even if I copy one of the songs, name it that, and add it to the .ini. Fucking wonderful.

Windowed mode (Software Renderer):
Attached is my DxWnd config file for you to try, you have only to change the path to the game clicking on Modify to change it.
I also uploaded a copy of the executable files for my game patched up, no game copyrighted assets here, so this link does not contain piracy material, it's only the executables and files in the game's root directory (no music, no maps, no graphics in this)
Given the "nightmare" that it is to get this game running, this should provide an easier kickstart for people that want to enjoy the game hassle-free.

I was also able to Extract and Re-Compress the SMK Smacker movie files for those interested in keeping an install of the game without movies, for those who already finished the game. It's possible to make the game's directory as low as 150MB with this. (if you also replace the music files with empty mp3 files) Check the other thread I created for the Smacker video codec files.
It's interesting to notice that my default retain GOG version was throwing errors after installing, I could not run the game. But the fanmade patch EXE worked without hesitation.

I have this same exact problem. Any help is most welcome!

Well, it took more than two decades. But thanks to NVIDIA and ATI cards finally giving you the option to add framerate caps to individual games, the Interstate '76 Arsenal is FINALLY 100% playable on modern PC's with very little extra tinkering (at least, for me). :)

Here's what you do:

1. Get the game from GOG.

2. Create desktop shortcuts for "i76.exe" and "nitro.exe" (you will NOT be playing these games through the launcher), right click and go into "Properties", and add the following command line parameter to the end of the file path: "-glide". Do this for both executables.

3. Also, set them to run in "Windows 98" compatibility mode and with 16-bit color.

4. Go into your video card's control panel, create a special settings file for i76.exe. Turn on all the texture filtering and anti-aliasing options (since we're not using dgVoodoo, the game is stuck at 640x480 resolution) and set the maximum framerate to 20 FPS. Do the same for nitro.exe.

5. This is if you'd prefer to play the game at its original aspect ratio, rather than stretched out to 16:9 or 16:10 (and I highly recommend you do, since stretching the graphics makes them very blurry). In your video card's control panel, turn on GPU scaling (details can be found here: https://steamcommunity.com/.../dis.../0/1608274347725261520/)

6. You are now ready to enjoy one of the coolest PC games of the mid-late 90's. A game that, to this day, has never really been duplicated or outshined.

Good day, thank you for posting this (and to other pages on Facebook). I'm trying to follow this step but my Nvidia Controls do not see the program. I tried to look for programs not on my computer, but still do not see Interstay 76. I found Interstate 82 but no luck on Interstate 76 or I-76. Any advice?

I can't beat mission 5 because I get to the ramp at the end and my car physics just say LOL NO DICE SUCKAHHHH

That's very odd. Are you in "Manage 3D Settings" at the "Program Settings" tab? The option to "Add" a program should be there, which should then let you browse your computer for the "i76" executable.
