Wow!  Very good progress here!
Some loose idea regarding functional testing... maybe useful, maybe not. Recent 8501 replacements (i.e. standard 6502 + additional logic) generally still fail to run a few programs. One good example is High Technology by Methabolix. I don't know the exact reason for that, I have no such replacement cards yet so that I could test that myself. I merely suspect that there could still be some issue with regards to how the onboard I/O port is implemented. It's known that Coby used to use both a fastloader and a code protector very picky about timing and exact I/O behaviour. ( High Technology already fails to run if one of the datassette buttons is left pressed...) Maybe it'd make a good candidate to be part of some compatibility test "suite".
