So far I have only tested the game on WIn-UAE, a real Amiga and PS-Vita (via emulator) and there were no problems. Please have a look at the configuration

Your windows pre packed version comes packed with fsuae and has a normal default config.
What I'm saying is out of the box your windows download link is not displaying the gfx properly in windows...
And I'm not sure how fix the gfx by editing the uae. I tried to enable vsync in uae but it didn't change anything
Can you repack the game with winuae instead of fsuae in your windows dl link?
