This is remarkable. Thanks so much for transcoding it. On the higher levels, it seems as though the warp gates no longer slow down the ghosts. I'm not good enough at the original to know whether or not that's normal.
And now for something completely different...
A transcode that I'd personally throw money at would be bringing Mr. Do to the Amiga 500. If you decided to do that someday, I have an idea that could set it apart from all other ports and transcodes. The default pathways that the monsters follow are numbers. In the background, you can see that the paths form numbers like 2, 3, 4, 5, 6, etc.... What if the game was exactly the same as the arcade, except that when you get to the last number level, it's followed by A, B, C, D, E, etc.... That should result in a bunch of extra levels/screens since the monster A.I. should do the rest.
