Iwoodford238, like the guest said, more games cannot be added to an mpx player. The factory firmware that comes with it determines all the features that it can have (i.e. you cannot add fm to non-fm playing player, etc.)
WARNING: do not try to upgrade your player to get more features...as you will cause yourself a lot of trouble. The only firmwares that a player can be ugpraded to must have the same format as the original...and the chances of finding such a firmware is extremely low.
So learn to love your player the way it is
