That's it! I've been browsing mobigames for quite a while looking for IBM Compatible old games and it never occurred to me to look for a category like that. It turns out the game is an unmamed cartridge for Arcadia Multi Select system with ports to different platforms. I could play at least the DOS version included on the softlist... not as pretty as the original though.
Looking in retrospective Amiga systems were rare and probably really expensive. The version I remember must be the Atari ST port.
