Version differences[edit]

A later version known as the "Gold Edition" was released which improved the graphics on the original game. It also came fully updated (version 1.2).
Interstate '76 was once bundled with Microsoft's Sidewinder Force Feedback Pro controller line up under the name "Sidewinder Force Feedback Pro Edition" (version 1.06). These copies often were bundled with graphics and computer manufacturer's hardware.

Essential improvements[edit]

Patches[edit]

You can find updates to the original retail, including the Gold edition patch, here. Note the GOG.com version is fully updated, thus these are unnecessary if purchased from there.
Nitro also has a Patch I & II, though these were only ever beta. Instead use the Unofficial Nitro Patch III.

Graphics option Option WSGF Notes
Widescreen resolution
4:3 resolutions only. Higher 4:3 resolutions can be forced for the Glide or Direct3D mode by using a wrapper such as dgVoodoo 2 (this does not change the aspect ratio, so widescreen resolutions will be stretched from 4:3).

Windowed
For software, a windowed mode can be activated by using the -gdi parameter. Unfortunately some have mentioned it to be broken on modern Windows. D3D and Glide can be forced in certain wrappers.
Borderless fullscreen windowed
See the glossary page for potential workarounds.
Anisotropic filtering (AF)
Use a glide wrapper then force in control panel. Some wrappers provide this option builtin.
Anti-aliasing (AA)
Use a glide wrapper then force in control panel. Some wrappers provide this option builtin.
Vertical sync (Vsync)
Can be forced through the graphics card control panel.
60 FPS and 120+ FPS
See High frame rate.

High frame rate[edit]

Frame rates higher than 30 FPS (24 FPS in some cases actually) cause stuttering, physics and enemy AI problems.
Force a frame cap in your graphics card control panel.
Nitro Pack users can get around this by using the NITRO.EXE-30FPS PATCH.
A similar patch for the base i76 game (GOG.com only) by user immi can be found here.
  • Versions of his patch that limit frame rate further can be found here.

Multiplayer types

Type Native Players Notes
LAN play
8 Versus
Uses old IPX protocol which is no longer supported on modern Windows. See IPX protocol deprecated for more. Could also try a Null-Modem emulator though this would be presumably slower.
Online play
8 Versus
Requires a direct internet connection (cannot be behind a router). Can be bypassed by using a tunneling program such as Tunngle. Nitro Pack users can get around this by using the Unofficial Nitro Pack Patch. GOG users should grab the version from here instead (no cd-check). A similar, though less robust, patch for the base i76 game can also be found in the later link.

Issues fixed[edit]

Corrupt graphics on Windows Vista and Windows 7[edit]

Use palette fix[citation needed]

See Rainbow color problems in older games.

Crashes on XP[3][edit]

Open up the file database.mw2 (.tvf in Nitro) in a hex editor and find the last two "RIFF" extensions. Change them to something else, such as "PIFF". Alternatively, download this (or this for Nitro) pre-patched version.
Disable hardware acceleration for audio devices or disable sound in game.

Won't install on 64-bit systems[edit]

A German website has a custom installer here. It also includes and installs the patches, up to the Gold Edition.
The setup.exe wont run on 64-bit computers due to the fact that 16-bit compatibility and DOS support was removed from theses versions. Luckily the files on disk are not compresses and can merely be copied over.
Installing the game (retail only)[citation needed]
  1. Create a folder in the following path and copy the files into it: C:\Program Files\Activision\Interstate '76\. You can leave the folders "AVI", "Demo", and "Direct X" and, of course, the setup.exe. Although the game can run just fine now, you can't install patches without registry keys (if you have the fully patched Gold Edition you can skip the rest).
  2. Open Registry Editor and add the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\I76.exe.
  3. Now add the following strings: for "Name" add (Default), for "Type" REG_SZ and "Data" add this path C:\Program Files\Activision\Interstate76\I76.exe.
  4. Add yet another string with the following: "Name" Path, "Type" REG_SZ, "Data" C:\Program Files\Activision\Interstate76.
  5. You need to create another key now, HKEY_LOCAL_MACHINE\SOFTWARE\Activision\Interstate '76\1.06. Note that the 1.06 at the end may differ depending on your game version. Now back up to the "Interstate '76" part of that key you just made and add these strings: "Name" EXE, "Type" REG_SZ, and "Data" i76.exe. The update should now be able to detect your game.
You may also be able to perform this more quickly by saving the following file as i76.reg and running it to add the keys:
REGEDIT4



[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\I76.exe]

"(Default)"="C:\Program Files\Activision\Interstate76\I76.exe"

"Path"="C:\Program Files\Activision\Interstate76"

[HKEY_LOCAL_MACHINE\Software\Activision]



[HKEY_LOCAL_MACHINE\Software\Activision\Interstate '76]

"EXE"="i76.exe

[HKEY_LOCAL_MACHINE\Software\Activision\Interstate '76\1.06]

Textures are "flipped" with other textures in glide mode[4][5][6][7][8][edit]

This is a bug in some glide wrappers. Reduce the texture memory to 2MB to get around this.
If you are running a real VooDoo card, add the following to a batch file followed by the game's executable:
SET SST_TMUMEM_SIZE=2
nitro.exe

Game crashes after mission 12[edit]

Official response from Activision rep:[9][10]

"This problem can be fixed by retrieving the I76shell.dll from the 1.06 or 1.08 patch for the original I76 W95. Do not install the 1.06 patch to the Gold Edition! It will crash. Instead, extract the 1.06 patch to a new folder. Copy the I76shell.dll file to the Gold Edition directory. Only 1 file will be replaced.

I tested Gold i76 using the i76shell.dll file from the 1.083 patch. It worked! I was able to get into the 13th level without a page fault crash. Be sure to back up the original .dll file though before doing this. The Gold edition will crash on Instant Melees with 1.08 .dll file installed. I would only use the 1.08 file temporarily for the purpose of gaining access to the 13th level."

You could simplify this process by renaming the patch dll to I76shell_1083.dll (GOG.com version already includes it), then using the following batch scripts to enable and disable the fix. Name them as such:

EnableM13.bat

@echo off
if exist I76shell.bak goto error
ren I76shell.dll I76shell.bak
ren I76shell_1083.dll I76shell.dll
goto fix

:error
echo Mission 13 Fix already enabled! If you are experiencing crashes in
echo melee or other single player missions, run RevertM13.bat instead.
pause
goto end

:fix
echo Mission 13 Fix enabled. Run RevertM13.bat to disable.
pause
goto end

:end

RevertM13.bat

@echo off
if exist I76shell_1083.dll goto error
ren I76shell.dll I76shell_1083.dll
ren I76shell.bak I76shell.dll
goto fix

:error
echo Mission 13 Fix NOT enabled! If you are experiencing crashes in
echo mission 13, run EnableM13.bat instead.
pause
goto end

:fix
echo Mission 13 Fix reverted. Run EnableM13.bat to re-patch.
pause
goto end

:end
