Brand new MV-1B board with Unibios V2.3 installed, which allows you to perform Gameshark functions and then some on your NEO GEO MVS unit.  SNK will sometimes censor certain games which minimizes the intensity and game play mood tremendously.  With the Unibios chip, you'll be able to unlock certain censorships and play the game the way it was intended.

 

This MV-1B board connects to your JAMMA compatible cabinet and will allow you to play NEO GEO MVS games, which are quite affordable and attainable compared to it's AES (Home Cart) counterpart. 

 

This board is rare in that it has been out of production for quite some time and is no longer produced.  The cart loads horizontally, compared to all their other models that load vertically, which is space saving in terms of vertical clearance.  A great unit to modify/consolize for home use as well as it's compact and sturdy.
