Mr. Do! vs. Unicorns

Released with Mr. Do! as part of Dempa's
Video Game Anthology series. Mr. Do! is played
if you insert the disk on Disk A drive.
Mr. Do! vs. Unicorns is played if you insert
the disk on Disk B drive. Both games includes
a Sound Test (by pressing F1), but
Mr. Do! vs. Unicorns was ripped in Hoot, that
is much easier than using MESS.

Also, the screenshot was taken from the
Disk Loader screen, due to the original title
screen is just the same as the original arcade
game (most games released in VGA series are
played by some kind of emulator).
