The debug cartridge is a virtual "cartridge" which provides a few features for automatic testing and debugging.

primary features

The primary features are the minimal features required for the Testbench.

  • one register in I/O space. when a value is written to this register, the emulator exits with the respective value used as exit status code.

the respective memory locations have been choosen so they will most likely never collide with any kind of extension, allowing to also test cartridges and i/o extensions.

secondary features

These are additional features not required by the testbench, which could be useful to debug software running on the emulator

Feature Wishlist

  • output CPU status (registers, flags) and timing info (cycle count, rasterline) to console of the host
  • output strings to the console of the host (printf-alike, allowing memory peek)
  • load and save blocks of memory from the host
