Editing the EXE file.

But doesn't the game settings allow you to change the resolution?

The settings work differently (all screenshots above were taken in 1920x1080; the game has a limit of 1024x768 for the interface resolution, and everything is scaled accordingly).
No, I knew about modifications in version 5.5, but I didn't delve into them (because I'm too slow for that 🙄). But there was a glitch in my brain when I changed the values from (1024 and 768) to (1920 and 1080), and these values couldn't be found in the Hex editor, and essentially the changes are not significant at all - . In principle, I don't understand much (maybe there are other obvious numerical values that can be easily changed), so I thought this information might be useful to someone 🖖.
