Today, I have slightly improved my 6502 CPU emulator by allowing to trace the kind of memory access on the memory bus during the fetching, decoding and execution of an instruction, which is pretty cool for debugging / tracing purpose (and potentially to help relocate SID files!) ✨

I'm sure I've missed plenty of opportunities to use the Z3 solver https://github.com/Z3Prover/z3 in the past. I really should think about it more often. 🤔
I'm curious: has anyone on the Fedi been using it for interesting problems? What's your experience with it?

Tried to register on CSDb yesterday to maybe ask some coding questions... but failed miserably with my near-zero C64 pedigree 😁
Even if I ever release a demo, I won't retry. Communities too often drift into orthodoxy & "us vs them" vibes. Totally fine if some enjoy that - I don't. ☺️
