I am almost done porting Dr. Mario to the Play Date
I hope to be done the final bit of logic (the tile clearing/scoring system) tomorrow and wanted to share my progress
It saves/loads the highscore, uses the crank to set the virus level and rotate the pill (though A/B also do it), and has the proper menu/intro/giftwrapper pictures (though I can't see those in the simulator), and on low/medium difficulty it shows a ghost pill at the bottom of the screen to indicate where it'll land.
The bad news is I'll be charging $2.50 in the hopes of paying off my PlayDate, which won't even arrive till next year ;_;
