There have been several accessories made for the Nintendo 64 console called Paks. These paks each have there own unique features and I will lay them out for you:
Rumble Pak: As suggested in the name, the Rumble Pak when attached to the back of the controller and with a compatible game can initiate a Rumble feature (shaking of the controller, vibration) to make the gaming experience more unique.
Transfer Pak: As suggested in the name, the Transfer Pak allows players to transfer specific data to compatible games, the transfer of data will be from a Gameboy game inserted into the pak and the pak will then be attached to the back of the controller. Also with the Pokemon games such as Red and Pokemon Stadium its possible to play these games rather than on the small Gameboy and without needing batteries.
Controller Pak: This is a memory device which externally holds data for certain games. This pak just like the others can be inserted into the back of the controller and with certain games players will be able to store or save data from those games. Some games require this accessory to save data such as Castlevania 64 and its sequel Legacy of Darkness.
Rumble Pak+Controller Pak: A combination of the two items where the controller pak is internally placed inside the rumble pak that way players can store data and use the rumble feature at the same time.
Jumper Pak: The original pak that is inserted into the Nintendo 64 console deck to display the games visuals. This pak didn't take into account the high amounts of graphical quality Nintendo originality wanted therefore a revision was created called the Expansion Pak.
Expansion Pak: The successor to the Jumper Pak, this special pak includes the necessary amount of power to allow players to experience the amazing visuals of the Nintendo 64. The pak became important enough to have most games require it to play them. Certain games even allow players to enhance the visuals with the pak or leave them in there original form if they please.
