Sorry for responding so late but I got behind in reading email.

Isn't the idea of the cartridge to test actual cocos? Unless seriously broken
in ways I can't imagine possible a 6809 or 6309 is always going to clock cycle
accurate. In the case of an emulator running on a PC or FPGA it should be up
to the author(s) to indicate if it's clock cycle accurate. It's well known that
the "cpu" on the coco3fpga isn't cycle accurate and neither will anything based
on that core.
