WinUAE Debugger - Audio Register Breakpoints

SparkyNZ · 14 June 2015, 07:07

This is probably one for Toni

I am trying to find out whereabouts the audio registers are being accessed in a game but I am confused by the syntax of the 'w' command.

Looking at WinUAE's source, there is an "AUD" mask that I can use.. but what range of addresses do I run the 'w' command over? Is it the address of the custom registers themselves or the address of the entire chip memory (I am emulating a 2Meg chip Amiga).

e.g. w 1 dff000 fff AUD ???

AUD (and others) are for breaking when enabled DMA channel accesses chip ram. CPU accesses only is the default.

If you only want to break to debugger when audio registers are accessed by CPU, w <num> dff0a0 40.

If you want to break when audio dma read next sample word from chip ram, w <num> 0 200000 AUD

Awesome! Thank you. I thought I tried "w 1 dff000 fff R" yesterday and that didn't work.. But "w 1 dff0a0 40" worked like a charm. Thanks Toni.
