Baseline (Widescreen) Solution & Issues
I created a new Solution via Hex edit and CheatEngine.
In the files available from the PC Gaming Wiki Community Files (search there). choose your Version and extract it into your Game root folder. Run the Game and select your des. resolution.
Now ALT - TAB to your Desktop and run the CheatEngine File, attach it to the right EXE and back in Game press F1 to get your HUD back.
