Baseline (Widescreen) Solution & Issues
i found a Solution for an old Game: EVIL TWIN
In the root game directory open up "fnx_core.dll" with a HEX editor. Search for all or part of the following HEX values...
640x480 = 8002 E001
C9 7F 7F 9E C9 7F FF 80 02 00 00 E0 01 00 00 10 00
change it too
1680x1050 = 9006 1A04
C9 7F 7F 9E C9 7F FF 90 06 00 00 1A 04 00 00 10 00
and save.
Now if you choose 640x480 you will have 1680x1050 in the Game.
