The N64 Transfer Pack is a device for the Nintendo 64 that allows the transfer of data between the system and a Game Boy or Game Boy Color cartridge. The Transfer Pak has a Game Boy Color slot and a part that fits onto the expansion port of the Nintendo 64. This was included with Pokemon Stadium and was used to transfer your pokemon from Red, Blue, and Yellow to Pokemon Stadium, this was the first time your favorite Pokemon could be seen in full 3-D.
