I have the ROM for v1.1. What was in the original? It appears to be the v1.0 binary I have, but the first two bytes of that are "DK". It doesn't translate to a known 6809 opcode. BUT it does run in Mocha, and says it is just "DOWNLAND" ... not "DOWNLAND V1.1".

There are 31 doors on the map from the cocopedia. 30 pairs and then the "final" door which takes you back to the beginning. I'd like to find the definitions of these doors and see the special "reset" code sequence.

There is no ending "congratulations" sequence. When you go through the last door, the game resets and you are back at the beginning:
