Yes - the multiple versions is maybe getting a bit much! I was planning to simply include both versions on a single d64 and perhaps you select which version to load from the boot file (I think that is what you are getting at?). Good idea!
Got it! Yes, for my new project I’m building multiple control schemes in from the ground up. With Broken Crown, the control handling was baked in fairly early and memory is already extremely tight, so adding all schemes cleanly into a single PRG this late in development may be tricky. I may still experiment with it though — it’s definitely a good idea.
