I wrote a small article today, where i describe how to get the game started on real hardware via disk or Sd2iec. You can find it here: https://www.windigo-design.de/wp_articles.html
Finally came back to it. I have tried loading it via pi1541, with and without the Epyx cartridge plugged it. The RED light stays on the pi1541, but after 5-10 minutes, it just stays on and locks up.
