Were there ever any remote debugging tools for the Atari ST line of machines? When developing games in full screen modes, switching away to a debugger seems quite cumbersome if you need to remember what was on screen.

Are there any remote debuggers that can either show the disassembled binary or actual C source?

Db is a debugger for the Atari ST and TT series of 68000-family computers... Db can use any of the ST's character devices for its input and output, including the screen, the serial port, and the MIDI port... Db is capable of debugging programs running on one machine while the bulk of the debugger runs on another.

It lets you view the state of the registers and the memory, and there's a way to load symbols, presumably to make the disassembled code easier to read? Maybe someone who has actually used it can describe the workflow.

  • Nice, I'll check that out! Impressive that it can use the MIDI port :)

    @Matt In fact, they recommend using the MIDI port because it's faster than serial and frees up the serial port for other uses. Commented Jan 5, 2017 at 21:16
  • Wonder if I can get that going with a USB->MIDI adapter... will definitely have to play around with this, sounds very useful!
