I am debugging a game under DOSBox and would like to see code where it output MIDI notes (for music). I suspect this is either done in the main loop or in the timer interrupt handler.
Ideally, I would create a breakpoint that activates when anything is written to 0x330 port (using OUT dx, al). Am I right ?
Is this something possible in DOSBox ?
I already read the guide : Guide to the DOSBox debugger
but it does not help.
