neura engine patches

the DLL source code that is used with the neura GSC mod.

this should support most of IW8, S4, IW9 out of the box. JUP is a seperate project to enable further development, though the IW9 work here can be used for it very easily.

• you must own a license to the game(s) in order to use neura.
• neura's engine and GSC will always be free and Open Source for anyone
• neura is only usable offline and is not to be used as "cheats" or "hacks"

how to compile

1. run generate.bat
2. go to build/ folder, open the .SLN file for Visual Studio 2026
