Soooo... about that. If you were interested in exploring that possibility then we should talk. I have ideas. And some experimental code that might help. 😁

Changing Waves by @4matofficial.bsky.social composed for our Chipo Django 2 music disk a couple of years ago. It's both an amazing tune and technically astonishing, making extensive use of the EFx command to rewrite the samples during playback. A real sonic journey. youtu.be/xhUI6r4MRhM?...

A few years ago I used your Apple II source to port PoP to the BBC Micro! bitshifters.github.io/posts/prods/... It took me nearly a year, with graphics and sound updated for the hardware, but it was a ton of fun and I was constantly impressed for how advanced the original game was for its time.
