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.
Good job.x86? We ain't got no x86. We don't NEED no stinking x86!

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