This is an old bug. The only solution is to avoid jumping backward in that specific room. Use SDLPoP (mentioned above) to fix this collision bug permanently.

Unzip the folder. You will see a data/ directory that contains placeholder files. You need the original PRINCE.EXE , PRINCE.DAT , and PRINCE.SAV files (from the DOS version). Copy those into the SDLPoP folder.

A: Yes. Use SDLPoP or DOSBox. Both run perfectly on Windows 11 (64-bit).

Pro tip: For better sound, edit the DOSBox configuration file (dosbox.conf) and change sbtype=sb16 and oplmode=auto .
