You know, I had some slightly better luck using PCAE for Windows' debugger
now that I have a stronger idea of what I'm doing. If you have DASM generate
a listfile, you can see which of the zero page values are going to be
assigned what name in the code, and you can pull up a similar reference
for the unique Stella special memory locations. (Why they couldn't make
one more window, that showed each Stella label and its corresponding
memory value rather than making you look it up in the grid, I'm not sure)
Anyway, that was enough to let me accuratey recreate the Pterry sound
from 2600 joust, I found the values of AUD* registers.
I had less luck coordinating the list file ROM instructions and PCAEWin's
view, but I didn't try all that hard.
PCAE Win's interface is just missing a few features that would make it
much easier (like, a simple 'advanced one frame' button rather than having
to keep reentering "go to scanline 1) over and over) and it would be WONDERFUL
if it could read in a listfile and show the variable names and source code
lines along with the memory location values and generated ASM, respectively.
But right now, I kind of fear for PCAEWin's health...its website
http://pcae.vg-network.com/ has been down for a bit.
(Though there seems to be some indication it was open source...does
anyone know about that, or have snagged a copy of the source?)
Anyway, it might be more feasible to adapt PCAEWin's source than
Z26's. (Actually, does Z26 run in a window? I always use it
fullscreen. PCAEwin's window'd nature makes a debugger easier
a bit. Also, I've done some debugging in PCAWin by recording
an AVI, and then bringing that into Animation Shop, where I can
inspect it frame by frame.)
