CPU is both a processor and the main bus (ROM, RAM, WRAM, etc), APU is the shared memory by the SMP+DSP (eg use it to catch writes from either chip); PPU probably won't ever be used since it's broken down into three separate buses (VRAM, OAM, CGRAM), but DSP could be useful for tracking bugs like we found in Koushien 2 with the DSP echo buffer corrupting SMP opcodes. Technically the PPU memory pools are only ever tripped by the CPU poking at them, as the PPU doesn't ever write. I now have run.for, run.to, step.for, step.to.

Added in the tracer mask, as well as memory export, as well as VRAM/OAM/CGRAM/SMP read/write/execute breakpoints, as well as an APU usage map (it tracks DSP reads/writes separately, although I don't currently have debugger callbacks on DSP accesses just yet.)

set their source. Eg "vram/hex 0800" or "smp/breakpoints.append execute
ffc0"; default is cpu.

These overlap a little bit in odd ways, but that's just the way the SNES
works: it's not a very orthogonal system. CPU is both a processor and
the main bus (ROM, RAM, WRAM, etc), APU is the shared memory by the
SMP+DSP (eg use it to catch writes from either chip); PPU probably won't
ever be used since it's broken down into three separate buses (VRAM,
OAM, CGRAM), but DSP could be useful for tracking bugs like we found in
Koushien 2 with the DSP echo buffer corrupting SMP opcodes. Technically
the PPU memory pools are only ever tripped by the CPU poking at them, as
the PPU doesn't ever write.

I now have run.for, run.to, step.for, step.to. The difference is that
run only prints the next instruction after running, whereas step prints
all of the instructions along the way as well. run.to acts the same as
"step over" here. Although it's not quite as nice, since you have to

Logging the Field/Vcounter/Hcounter on instruction listings now, good
for timing information.

Added in the tracer mask, as well as memory export, as well as

usage map (it tracks DSP reads/writes separately, although I don't
currently have debugger callbacks on DSP accesses just yet.)

Still thinking about how I want to allow / block interleaving of

So ... remaining tasks at this point:

  breakpoints during synchronization, or abort a save in a break event.)
