Yeah, that's what I mean. It's an old game, and I remember that you need to do some tricks to play it on a widescreen.
Take a look, but I would try to fix it if possible, because that way the result of modding will be better. Otherwise, your icons should be square, but during testing, you see them as rectangles, which means they don't look the way your users will see them.
But overall, good job, good luck.
That's funny, everything seems to work for me without any tricks. I just chose one of the resolutions in the settings that doesn't stretch the screen.
