The game was tested on multiple real amigas and emulators. It is not tested on "theA500 mini", but since it is an amiga emulator itself i assume that the lha or any other versions should work on it (actually they are all the same version).

The xml file for whdload on amiberry emulators, of which the A500mini is one, does have your demo listed but not the full game. I'm not quite sure how they get the information for new games though. https://github.com/HoraceAndTheSpider/Amiberry-XML-Builder/blob/96d6f1b976454682...
