this looks like a freeware game, have you tried the compatibility mode? (right click the executable, choose properties, choose compatibility, set to xp), there's a chance it could help, otherwise i think the game rare enough you'll just have to hope to find someone who solved it on some forum. unless someone has some more tips

an 'extreme' tip is to create a vrtual machine with win xp installed just for this, i guess that would work

This game runs smoothly on my Windows 11 natively. However I saw a graphical oddity that I can't be certain if its an issue or not.

The game ran a little faster for me with DxWnd. dgVoodoo2 should run it fine too

Yeah I have tried this, didn’t help.

These old Japanese doujin games were written in old engines and Windows 11 natively emulates these old graphics layers – the result is often slow, the sound breaks up or the framerate is low even in non-demanding games. Windows 11 "somehow" stimulates long-abandoned old graphics features and the result is lousy. Characters are not drawn correctly, etc. It may not be as noticeable on a powerful computer.

Try again.
Runs well on my Windows 10 system using DDrawCompat (without it there are graphical problems).

Yeah but I don't know what specific settings I should use. ChatGPT didn't help much either, I spent several hours on it.

WTF, what do you need ChatGPT for?? Read the instructions https://github.com/narzoul/DDrawCompat
You don't even need to change any settings for this game, just drop the dll next to the executable.

OMG yeah, problem solved, thank you so so much! It was just copy and paste the draw.dll
Amazing!
