I've got the Amiga disks for RSI Demomaker but never used it as it seems to require ECS and Kickstart 1.3 or older. I may be wrong about that but it doesn't work quite right on my A1200.
It should work under Amiga Forever but you'll have to tweak the settings, and you can't read Amiga disks very easily on a PC since PC floppy controllers are wonky compared to the Amiga.
