I dont think I understand, is there like specific way it has to be used?
This game only runs on a Commodore 64 (real thing or emulators). Common C64 emulators or drive adapters support various file formats (.prg, .tap, .d64., .crt).
A .prg file can be drag'n'dropped into a C64 emulator like VICE. Or you can copy it onto an USB drive and load the .prg file on a C64 Ultimate or The64 (mini/full size) for example.
Does this answer your question?
