Sorry for the double bump, but here's some images from the games, taken with MAME:

PC-10 Dr. Mario:


Vs. Dr. Mario:


See that? The Vs. version has a coin counter at the bottom. The PC-10 version is for all intents and purposes the same as the standard NES console release, with the exception of the timed method of play and the game selection screen (both handled by the PC-10 system).
