Dealing with a non-deterministic bug in 65816 assembly is incredibly hard. But it is also intensely satisfying when you manage to fix such a bug.

Writing self-modifying code. I feel so naughty. #CommanderX16

Off-by-one errors are annoying. Off-by-one errors when working in 65816 assembly are double annoying.

Passing arguments via the stack on a 65816 is extremely error-prone.

Back from my day job business trip with a few orders to fulfill! But as teased, here's a video showing off TurboWave and TurboTracker using several PCM samples (and a few wavetables)

Looks like I may have found another bug in the #CommanderX16 emulator. Not even going to investigate further. The broken instruction is easy to replicate with a bit of self-modifying code. I kinda love 8 bit bare metal coding.

Just used the 65816 mvn instruction for the first time. A bit fiddly, but useful. #CommanderX16
