Hello,
I've looked into this game. Resolutions are indeed hardcoded in these three dll's. I've forced the game using IDA and OllyDBG to run in 1280x1024 but it crashes as soon as mission starts however loading shows correct forced bigger resolution.
Key to the crash is hidden in Game_exe.exe however this exe doesn't look like a 32-bit executable file (maybe 16-bit?) and is not debuggable thus I can't do anything with it.
Start.exe looks like a launcher for Game_exe.exe
I don't see any other possibilites. Maybe hooking ddraw.dll but It will crash game too. It needs to patch Game_exe but it can't be debugged as I said earlier.
Resolution is hardcoded at the beginning of the file. Function called then is located at
