The manual "Programming the 65816 Including the 6502, 65C02 and 65802" available from The Western Design Center has a chapter describing and giving the source code for a program called DEBUG16 that can perform disassembly and instruction tracing of 65816 machine code. I ported the code to the CC65 assembler and got the disassembler running on my Replica 1 computer which has been modified to support a 65816 CPU. I haven't yet got the trace code ported and debugged.

Details and a link to the source code can be found here on my blog: http://jefftranter.blogspot.ca/2012/07/ ... trace.html

I'll bet that port kept you up at nights for a while. :lol: Good job.

Nice one, thanks Jeff. It was tantalising seeing that code from WDC and then discovering it was unusable.
