I am a -debug newbie...
As a bit of arcade archaeology I am trying to experiment with the junofrst game and in particular looking at the way the sound processor works (mcu).
junofrst has a number of cpus (the main game, the z80 sound processor and a 8039(mcu) sound fx processor).
I would like to "focus mcu" and then communicate with it via setting two memory mapped latches... this seems do-able.
But... the running the other CPUs also run and they then overrun my experiments by writing to the latches (which causes a mcu irq).
Is it possible to run this game but suspend the cpus that are not of interest?
(I guess I could create a ROM set that has hard loops for the cpus which are not of interest but it would be nicer if I could suspend them).
Thanks in advance
