Is it possible to force this game into a windowed mode? Tried using various softwares that can do that with other games, but this one doesn't work. I was also digging through in-game files, but still no success. Bandicam can't detect this game and I'm afraid that OBS will slow down this game hard.

I think me and courte tried doing this a couple of months ago because he was having issues with capturing the game as well and we couldn't figure out any sort of solution. If you figure something out let us know, but I think the game is pernamently locked to play in fullscreen mode only.

The only way I can think of at the moment is to get Virtual Machine and record its window. The only downside is the time it takes to install OS in VM. So if courte is willing to waste ~40 minutes installing Windows XP, he should go for it.
