Game working on windows 10, repost from gog.com forum

[Skyline]

I'm using Windows 10 version 1511 build 10586.494 stable and GOG Galaxy 1.1.12 (beta).
(Venom) Codename - Outbreak version 2.1
Intel i5-3570k, AMD Radeon HD7970.

If your Outbreak.exe and other game *.exe start and keep running in the background causing high CPU load but does nothing..

Here is two simple steps to fix this:

1. Open your Codename - Outbreak root folder and find 2 files:
GAME.INI
winmm.dll

The first one MUST be about 22 KB size. If it 502 Bytes or something else then delete it and click Verify / Repair button at your GOG Galaxy client (or reinstall the game if you not using it).

2. Rename winmm.dll for example to 111winmm.dll.
Windows will be use own winmm.dll from System32 folder, but not the one from game folder.
After this all *.exe files in game folder must run correctly and not to cause high CPU load.

winmm.dll is Windows Multimedia CD Audio WAV player wrapper ( https://github.com/hifi/wav-winmm/ ).

3. Download Dgvoodoo2 here dege.freeweb.hu/dgVoodoo2/dgVoodoo2_55.zip
Copy 3 dll files from MS folder to Game folder.
This will fix menu and texture bugs.

That's all you need to do.

Optional: to change resolution, controls, settings and to disable intro movies use Config.exe and Forced.exe in the game folder.
If you change resolution to 1920x1080 by editing GAME.INI you probably will not be able to start mission because you will not see menu items "Single player" at the top and "Multiplayer" at the bottom. ;)
