There are stray columns of errors, but otherwise this is almost correct.

For now, at least, c800–cfff is always built-in ROM.
...
Otherwise I probably need to extend my c3 logic to cover the other built-in cards (?)
2020-11-18 19:49:45 -05:00

Advances slightly. I think I need a custom queue for RAM writes.

Takes a repeat shot at proper shadowing.
