Don't know if this is the place to ask, but is there a known source for the COP microcontroller yet? I'm willing to try writing a Verilog implementation if it will help finish this core.

Is it a COP420 or a COP421? Do we know for certain yet?

Is there a known way to test an implementation of the microcontroller to see if it is correct?

Please let me know if you can tell me, or let me know a better place to have this discussion if need be.

Haven't looked into the microcontroller at all I am afraid. That said, I suspect that the daphne codebase might have a 'black-box' style implementation of it. What's more urgent is completing the mpeg2 decoding via the ext-bus for the core.

Oh, I got the impression that was finished. What's missing? Is the current implementation not doing something it's supposed to?
