3eec88bf82 debugger: add a flag indicating that the debugger is accessing the bus; this is used to suppress unwanted side effects of reads (e.g. cothread switches, latch-on-read registers) and to allow ROM to be modified (in place of MappedRAM::write_protect(), which is going away soon)

Backport most recent MSU1 behaviour
 2015-04-21 13:03:40 -04:00

74c080cee7 Backport most recent MSU1 behaviour 
v073 has some shortcomings in MSU1 behaviour, most notably it ignores
the DSP mute flag (which will cut off external audio on a real SNES).
Hack authors stumble upon those when running on real hardware for the
first time after testing on less recent bsnes versions.

Backports from higan v094:
- audio error flag
- init behaviour (zero out MSU1 regs)
- initial volume
- DSP mute flag

218066c5c2 Debugger: fix duplicate DMA read 
DMA source is read twice in CPUDebugger::dma_read which breaks sources
that change state on read (e.g. MSU1 data). Read only once before
checking breakpoints and return the buffered result.
