A Galactic Experience

Could I ask someone who has managed to get this to run what they did?

I tried downloading from the site linked by @8bitAG but when I tried loading in H89Emu I got that the file was empty, when I tried the online emulator jsH89 I get that it doesn’t recognize it as a real disk, and I can’t try it in MAME because it asks for ROMs that seem to not exist.

The absolute best would be if it was packaged in a way where it would just run, but I’ll take instructions as long as they’re clear.
