The Bassmate Computer by Kelko has now been preserved in MAME smile

The unit was OEM produced by Nintendo and is very similar to the G&W Dual Screen units.

The Bassmate Computer is based on the Sharp SM511.

This is a screenshot from the game:

The unit needs to display overlays to make any sense though smile

Thanks to Mr. Do for providing the game!
