Considered the fact there are a lot of files in game's folder, it would be useful to put all files in another folder (for example "DATA") and leave outside only PUCKMAN.PRG.
On my real MegaSTE TOS 2.06 4MB I get the message "Machine non compatible". The same happens with Hatari. If in the emulator I change System from Mega STE to STE the game works. The game is great, please add Mega STE compatibility. Merci!
