On the MSX side, this version adds state saving.
Use F6 to save, F7 to load. I just finished Metal Gear 2 for the first time, using the new state saving function, which was a fun way to test this new function :-)

Another cool (non MSX related) addition is VirtuArcade, a 3D virtual arcade running 20 games at once. Just walk to an arcade, insert a coin and play right there :-)
