Hi, I've a suggestion about resolution.
With current monitor running at 1920 x 1080 or 1650*1050 the game doesn't shine
Some years ago I took my hands on the source code and fix partially the resolution change options.
It's not hard to create new resolutions, however each dialog in the code have hard-written coords, so it requires a lot of time to fixes them all.
If you like I can send you the files I have modified at that time just to see how to start the work.
I suggest really to replace the whole code for the resolution with new more flexible one (there are too many switch blocks).
Greeting,
Erik
