The Transfer Pak, known in Japan as the is an accessory manufactured by Nintendo that plugs into the Nintendo 64 (N64) controller. It allows for the transfer of data between supported N64 and Game Boy or Game Boy Color (GBC) games to access additional content. The Pokémon Stadium games, which the accessory was initially bundled with, also use it to emulate Game Boy Pokémon games on the N64.
The Transfer Pak is recognized as one of the first examples of connectivity between Nintendo's home and handheld consoles. It was supported by only twenty games released for the N64 and its 64DD expansion between 1998 and 2000, the majority of which were not released outside Japan. Several games that were initially planned to support the accessory were either cancelled or had the functionality removed before release. Digital re-releases of games with Transfer Pak support have also been inconsistent in retaining these features. As a result, retrospective coverage of the accessory has found it largely unnecessary. A similar accessory, the was designed to use the GBC as a second screen when playing 64DD games, but it was never released.
History The Transfer Pak was developed by Nintendo Research & Development 3, and was first revealed at Nintendo's Space World 1997 trade show. Nintendo game designer Shigeru Miyamoto cited it as one of several devices the company was exhibiting at the show that allowed for games with non-traditional gameplay, along with the Voice Recognition Unit and the Game Boy Camera. It was initially released in Japan as a pack-in with the game Pocket Monsters Stadium (1998), which required the Transfer Pak for many of its features. In North America and Europe, the Transfer Pak was similarly bundled with Pokémon Stadium (1999) for its English-language release in 2000, and received a standalone release shortly thereafter.
64 GB Cable At Space World 1997, in addition to the Transfer Pak, a similar accessory called the 64 GB Cable was announced by Marigul Management, a joint venture between Nintendo and Recruit. It was designed for use with the 64DD, a rewritable disk drive peripheral for the N64 that would eventually release in 1999. The cable would connect from an N64 controller port to a dedicated GBC cartridge, allowing players to transfer data between the GBC and a 64DD storage disk. Additionally, players would be able to use the GBC as a sub-screen for certain 64DD games.
The 64 GB Cable was first publicly exhibited at Space World 1999 alongside DT Bloodmasters, a trading card game developed by Game Studio and directed by Masanobu Endō. DT Bloodmasters was planned to use the cable to exchange cards between the two systems and allow players to privately view their cards on the GBC screen. The cable and DT Bloodmasters were ultimately never released due to the 64DD's poor sales, with the game being reworked into a standalone GBC game, DT: Lords of Genomes, released in May 2001. The N64 horse racing simulation game Derby Stallion 64 (2001), originally planned as a 64DD release, was intended to support the 64 GB Cable. The game would have used the GBC as a second screen to place private bets on horse races, but this feature was removed during its transition to a standard N64 release. The cable was also planned for use in an untitled Capcom game being developed in collaboration with anime director and Gundam creator Yoshiyuki Tomino. Another unreleased accessory from Marigul, the GB Socket, was designed to interface with the 64 GB Cable and allow Game Boy Color games to similarly connect to games on the Sega Dreamcast, such as connecting Sakura Wars GB (2000) to Sakura Wars 3 (2001).
Functionality The Transfer Pak plugs into the expansion port on the back of a Nintendo 64 controller, similar to other accessories for the system such as Controller Pak memory cards and the Rumble Pak force feedback device. It features a cartridge slot compatible with Game Boy and GBC Game Paks; when a Game Pak is properly inserted into this slot, compatible N64 games can read and exchange data with the connected portable game. While the device itself is physically compatible with all Game Boy and GBC games, most N64 games with Transfer Pak support can only connect to games from the same region.
Unlike the Super Game Boy peripheral, which allowed Game Boy games to be played on the Super Nintendo Entertainment System, the Transfer Pak's primary use is not to play Game Boy games on the N64. Nintendo and Intelligent Systems developed a separate accessory for playing Game Boy games on the N64, the Wide-Boy64, which was not released to the public; it was available only to game developers and members of the gaming press, and was used to capture footage and images from Game Boy games more easily. Datel also released an unofficial Game Boy player for the system in 1998 called the Game Booster, also known as the GB Hunter, which was poorly received. However, the Pokémon Stadium games include a built-in Game Boy emulator, allowing users to play compatible Pokémon games on the N64 by inserting them into the Transfer Pak. The emulation software is based on the Super Game Boy, including applying the same borders and color palettes during gameplay.
Supported games The Transfer Pak is supported by a total of twenty games, comprising eighteen N64 games and two 64DD games. The majority of these games were not released outside of Japan, with only six games released in Western markets that support the accessory. Games use the device for different purposes, including transferring progress between N64 and Game Boy, unlocking hidden content, and triggering special effects based on the connected Game Boy game. The following is a complete list of all compatible N64 and 64DD games, along with the corresponding Game Boy and GBC games.
