Did you buy the collectors edition with the cartridge?
The software on the cartridge is used to load the game faster, it has been upgraded a number of times from the original release, if you need an upgraded eeprom you can program the rom yourself if you have that capability. If not! I can do it for you.

NOTE: you can not use this cartridge rom by itself, it requires the entire package either digital or collectors edition to play the game.
