I'm not sure this is possible. When I first started the port, I knew
about some, but not all of the unsupported instructions and addressing
modes. I had to learn about the others the hard way :) I seem to
remember that there wasn't a good "insert-emulation-here" trap
happening when the CPU would hit one of these instructions. I think I
was just getting Address Errors.
