So i got my hands on this one tool where you can compile scripts for a game and im trying to get the code in the executable. But when i try and get a decompiler and decompile the program it says not supported. Is there anyway i can get the source code? Btw the decompiler i used was JetBrains- dotpeak
dotPeek is specific to .NET IL languages such as C#/Vb.NET and similar. If the program is coded in something else (C/C++/Delphi/ASM/etc.) then it will not work. You should first determine what language the program is coded in to determine the best route to take in terms of disassembling and getting some form of readable code back. If the program is not done in a higher level language such as a managed language like C# or similar, then you are not going to have any tools available to get the full source code back since none exist to fully decompile a lower level language such as C or C++.
