I still come back to LED Wars every once in a while! As a matter of fact, after a particularly heavy binge of the game, I started modding it slightly. Just using a hex editor, it was quite tedious to make even the smallest of changes, but I don't know of any other options lol. It was easy to edit units and buildings, since those files have actual text at the start of each corresponding section, then changing unknown values through trial and error. I remember giving the Constructor a weapon, creating a mobile SSSAM (which was the top of a Rocket Launcher on the body of a Heavy Tank), and many other random tweaks.

My personal favorite was finding a way the change the resolution! Took forever, but I remember getting 1024 x 768 and 1280 x 1024 to work. Only issue was that the HUD stayed at 640 x 480 in the top-left quadrant-ish, but this is definitely outweighed by the better FOV and the fact that high scroll speed doesn't make the game nearly unplayable. Here's a video with the higher resolution:

I also have some other videos showing the other tweaks I mentioned.
I haven't tried the game much on Windows 10, but I remember the toolbar with file, options, etc. stayed at the top of the screen while playing. This covered the amount of LED you have, which is rather important. At some point I might be interested in trying fixing this. If that's not possible, I could just swap the costs of everything between LED & seeds, with the possibility that it would break the AI. I'd also try to get 1920 x 1080 working lol.
