It is important to use a Kickstart ROM of an Amiga 500! And to use the A500 configuration in WinUAE! If you use newer Kickstart ROMs such as 40.063 (what I did) or 40.068 the game fails.
Thanks for the test Primax. I will add your information to the description next year and check which Kickstart version I used for the emulated Amiga 1200.
