Mogura Desse, Konami 1991
Hardware info by Guru
---------------------
This is a small test board. The game is basically a whack-a-mole type
game and has basic sound but the game is purely a bonus. The board is
primarily for testing the controls and setting up the screen and may
have been provided in non-dedicated empty Konami cabinets from the era
as there is (or was?) a Japanese law stating that arcade cabinets
could not be sold without a game included. If this is true then there
were likely many of these boards manufactured, but due to the simple
game may have been thrown away by arcade operators so how many survive
today is unknown.
