@LGB Hehe, no probs, glad to be your spell-checker on this occasion ;)
Yep, I hear ya regarding either patching the c65 rom or some light native dev environment.
When I saw Paul's blog post here, he hinted at the hypervisor-mode possibly having its own monitor too, perhaps that could be a good home for it too:
Hmm, this topic makes me wonder whether a disassembler ought to catch the "SED, SED, JMP" pattern, and display it nicely as a "JMPF", and an assembler take "JMPF $0080C0000" and break it down into "SED, SED, JMP...".
Anyway, maybe a nice dream for later :)
