# Nintendo 64 accessories

Nintendo 64 accessories are first-party Nintendo hardware—and third-party hardware, licensed and unlicensed. Nintendo's first-party accessories are mainly transformative system expansions: the 64DD Internet multimedia platform, with a floppy drive, video capture and editor, game building setup, web browser, and online service; the controller plus its own expansions for storage and rumble feedback; and the RAM-boosting Expansion Pak for big improvements in graphics and gameplay. Third-party accessories include the essential game developer tools built by SGI and SN Systems on Nintendo's behalf, an unlicensed SharkWire online service, and unlicensed cheaper counterparts to first-party items. In the fifth generation of video game consoles, the Nintendo 64 had a market lifespan from 1996 to 2002.

## First-party

First-party Nintendo 64 accessories have a product code prefixed with NUS, short for "Nintendo Ultra Sixty-four".

### Controller

The Nintendo 64 controller (NUS-005) is an "m"-shaped controller with 10 buttons (A, B, C-Up, C-Down, C-Left, C-Right, L, R, Z, and Start), one analog stick in the center, a digital directional pad on the left side, and an extension port on the back for many of the system's accessories. Initially available in the seven colors of gray, yellow, green, red, blue, purple, and black, and it was later released in translucent versions of those colors except gray.

### Controller Pak

The Controller Pak (NUS-004) is the console's memory card, comparable to those of the PlayStation and GameCube. Compatible games can save player data to the Controller Pak, which plugs into the back of the Nintendo 64 controller (as do the Rumble and Transfer Paks). The Controller Pak was marketed for exchanging data between Nintendo 64 owners, because data on the game cartridge can not be transferred.
The original models from Nintendo have 256 kilobit (32 KB) of battery backed SRAM, split into 123 pages with a limitation of 16 save files, but third-party models have much more, often in the form of 4 selectable memory banks of 256 kbits. Games occupy varying numbers of pages, sometimes using the entire card. It is powered by a common CR2032 battery.
Upon launch, the Controller Pak was initially useful, and even necessary for early games. Over time, the Controller Pak lost popularity to the convenience of a battery backed SRAM or EEPROM in some cartridges. Because the Nintendo 64 Game Pak format also allows saving data on supported cartridges, few first-party and second-party games use the Controller Pak. The vast majority are from third-party developers. This is most likely due to the increased production and retail costs which would have been caused by including self-contained data on the cartridge. Some games use it to save optional data that is too large for the cartridge, such as Mario Kart 64, which uses 121 of the total 123 pages for storing ghost data, or International Superstar Soccer 64, which uses the entire cartridge's space for its save data. Tony Hawk's Pro Skater uses 11 pages. Quest 64 and Mystical Ninja Starring Goemon use the Controller Pak exclusively for saved data. The Japan-only game Animal Forest uses the Controller Pak to travel to other towns. Animal Forest also had the ability to play Famicom games that were saved onto a Controller Pak. This second use was far less known, as only one game, Ice Climber, was released via this method through magazine giveaways.
Following the 1996 Christmas shopping season, Next Generation reported "impressive sales of the memory pack cartridges despite the lack of available games to take advantage of the $19.99 units".

### Jumper Pak

The Jumper Pak (NUS-008) is a filler that plugs into the console's memory expansion port. It serves no functional purpose other than to terminate the Rambus bus in the absence of the Expansion Pak. This is functionally equivalent to a continuity RIMM in a Rambus motherboard filling the unused RIMM sockets until the user upgrades. Most Nintendo 64 consoles were shipped with the Jumper Pak installed. Replacement Jumper Paks were not sold individually in stores and could only be ordered through Nintendo's online store. The system will not boot without a Jumper Pak or Expansion Pak installed.

### Expansion Pak

The Expansion Pak (NUS-007) consists of 4 MB (megabytes) of random access memory (RAM)—which is RDRAM, the same as on the console motherboard—increasing the console's RAM from 4 MB to 8 MB of contiguous main memory. It is installed in a port on top of the console and replaces the pre-installed Jumper Pak, which is simply a Rambus terminator. Originally designed for the 64DD disk drive's larger multimedia workstation applications, the Expansion Pak was launched separately in Q4 1998 and then bundled with the 64DD's delayed December 1999 launch package in Japan. The Expansion Pak was bundled with Donkey Kong 64, and in Japan, the Expansion Pak additionally was bundled with The Legend of Zelda: Majora's Mask and Perfect Dark.
All Nintendo Expansion Paks came bundled with an "ejector tool" (NUS-012) meant for removing the original Jumper Pak.
Game developers found ways to use the increased memory, including greater visual appeal. The Expansion Pak is required in order to run both Donkey Kong 64 and Majora's Mask. Perfect Dark blocks access to content, including the single-player campaign, when no Expansion Pak is present, and the game's packaging states that "approximately 35%" of the game is available in that case. It is required for all 64DD software. In StarCraft 64, it is needed to unlock levels from the Brood War add-on from the PC version. Quake II features higher color depth and better performance, but not a higher resolution, with the Expansion Pak. In the vast majority of games with support, such as Castlevania: Legacy of Darkness and Indiana Jones and the Infernal Machine, the Expansion Pak is merely used as additional frame buffer memory to enable various high-resolution (usually interlaced) mode options at a performance cost, in some cases dramatically so. This use of the Expansion Pak can be attributed to ease of implementation and games that mainly target the stock console; additional RDRAM cannot be easily used to circumvent other bottlenecks of the console, such as the small texture cache.
IGN celebrated the Nintendo 64 industry's methods in launching and supporting the Expansion Pak for making a high-impact accessory with "immediate and noticeable", though mostly optional, effects.
The original NTSC release of Space Station Silicon Valley may crash in certain places if the Expansion Pak is present.

However, lead artist Mark Stevenson called Marlow's story a "myth" and said that the Expansion Pak was committed to early in development. Though such a bug did exist towards the end of development, according to Stevenson, "the Expansion Pak wasn't introduced to deal with this and wasn't the solution to the problem." Nintendo said that the bundle would avoid consumer confusion. |

### Rumble Pak

The Rumble Pak (NUS-013) provides haptic feedback by vibration. It is powered by two AAA batteries and connects to the controller's expansion port. It was released in 1997 for the new game Star Fox 64, with which it was originally bundled.

### Transfer Pak

The Transfer Pak (NUS-019) plugs into the controller to transfer data between supported Nintendo 64 games and Game Boy or Game Boy Color games. It was released in Japan in August 1998, bundled with the game Pocket Monsters' Stadium, and in North America and Europe in February and April 2000 respectively, where it was similarly bundled with Pokémon Stadium.

### Wide-Boy64

Developed by Intelligent Systems, the Wide-Boy64 is a series of adapters similar to the Super Game Boy that plays Game Boy games. The device was never sold in retail to general consumers and was only provided to developers and gaming press outlets, who could purchase one directly from Nintendo at a cost of $1,400 (equivalent to about $2,643 in 2024). The gaming press used it to capture screenshots more easily. Like the Super Game Boy and Game Boy Player, the game screen is surrounded by a template mimicking the appearance of the portable system. The cartridge contains internal Game Boy hardware, allowing the system to run games natively rather than via an emulator. Two major versions of Wide-Boy64 were released: the "CGB" model for Game Boy and Game Boy Color games, and the updated "AGB" which added support for Game Boy Advance Game Paks.

### 64DD

The 64DD (NUS-010) is a 64 MB floppy drive with real-time clock, font and audio library in ROM, and a bundle of other accessories and custom games. The peripheral was initially announced in 1995, planned for release in 1997, and repeatedly delayed until its release in December 1999. It was launched alongside a now defunct online service called Randnet. With nine games released, it was a commercial failure and so was never released outside Japan.

### Mouse

The mouse (NUS-017) was developed for the 64DD's GUI-based games and applications, such as the Mario Artist suite, SimCity 64, and the web browser for Nintendo's defunct online service Randnet. It was manufactured by Mitsumi and was released only as a bundle with the 64DD's launch game, Mario Artist: Paint Studio. It works with Mario no Photopi, which was switched from the 64DD to Game Pak.

### VRU

The VRU or Voice Recognition Unit (NUS-020, NUS-021, NUS-022, and NUS-025) is compatible with only two games: Hey You, Pikachu! and Densha de Go! 64. Hey You, Pikachu! is packaged with the VRU and requires it, while the VRU is not required for gameplay in Densha de Go! 64 but does include it in the box. The VRU consists of a ballast (NUS-020) connected to controller port 4, a microphone (NUS-021), a yellow foam cover for the microphone, and a clip for clipping the microphone to the controller (NUS-025, bundled with Hey You, Pikachu!) or a plastic neck holder for hands-free usage (NUS-022, bundled with Densha de Go! 64). The VRU is calibrated for best recognition of a high-pitched voice, such as a small child's, and other voices are less likely be recognized properly by the VRU.
VRUs are region dependent, and foreign region VRUs are not detected by the games. No VRU compatible game was launched in the EUR region (PAL, Europe), so there is no EUR-region VRU. A similar device for the Wii is Wii Speak.

### Cleaning Kit

The cleaning kit (NUS-014, NUS-015, and NUS-016) contains materials to clean the connectors of the Control Deck, controllers, Game Paks, Rumble Paks, and Controller Paks.

### RF Switch and RF Modulator

The RF Switch and RF Modulator (NUS-009 and NUS-003) connect the Nintendo 64 and model 2 SNES (redesigned after the launch of the Nintendo 64) to the television through RF. It is primarily intended for older televisions that lack AV cable support. The RF switch itself is identical in every way to the RF switches released for Nintendo's prior systems (the NES and the SNES) and can be interchanged if needed. This set was later re-released for the GameCube to give it RF capability. The cables intended for the GameCube will also work with the Nintendo 64 and SNES.

### Euro Connector Plug

The Euro Connector Plug is an adaptor packaged with European releases of the console, which converts RCA composite and stereo cable inputs to Composite SCART.

### Video capture cassette

The video capture cassette (NUS-028), or cartridge, is for the Mario Artist 64DD game series. The back of the cartridge has audio, video, and microphone input jacks. It was bundled with the 64DD game Mario Artist: Talent Studio.

### Modem

The modem cartridge (NUS-029) connects at up to 28.8 kbit/s, for the defunct Randnet service and compatible 64DD games and web browser.

### Power supply

The power supply (NUS-002, UKV-EUR-AUS-JPN-USA) provides electricity to the Control Deck and 64DD.

### Keyboard

The compact keyboard is for the Randnet service and compatible 64DD games.

### SmartMedia

SmartMedia memory cards for Mario no Photopi contain images, backgrounds, borders, and other media assets for editing the user's photos. There are at least 10 different cards:
* Illustrations - Postal cards 1
* Illustrations - Funny accessories 1
* Characters collection - Yoshi's Story
* Characters collection - Sylvanian Families
* Characters collection - Bomberman
* Characters collection - The Legend of Zelda: Ocarina of Time
* Characters collection - Himitsu no Akko-chan
* Characters collection - Hello Kitty
* Characters collection - Card Captor Sakura
* Characters collection - Medarot
The cards are all 3.3 V 2 MB SmartMedia memory cards manufactured by Hagiwara Sys-Com. Mario no Photopi was bundled with an empty memory SmartMedia card for storing the user creations.

### ASCIIWHEEL 64

The ASCIIWHEEL 64 is an alternate controller shaped as a steering wheel for driving games, with an accessory port.

### Bio Sensor

The Bio Sensor (NUS-A-BIO-JPN) is an ear clip that plugs into the Controller Pak slot of the controller to measure the user's heart rate. It was manufactured by Seta and released only in Japan. It is compatible only with Tetris 64, which causes simpler or more complex shapes to drop depending on how fast the player's heart is beating. This device is similar to the unreleased Wii Vitality Sensor.

### Tsuricon 64

The Tsuricon 64 (ASC-0905) is a fishing controller manufactured by ASCII Corporation and compatible with a few fishing games released in Japan, like Bass Rush - ECOGEAR Power Worm Championship, Nushi Tsuri 64: Shiokaze Ninotte, or Itoi Shigesato no Bass Tsuri No.1 Definitive Edition!

### Densha de Go! 64 controller

A train controller compatible with just one game: Densha de Go! 64. It is similar to other controllers for the same game series on different platforms such as Dreamcast and PlayStation. The game optionally supports the VRU.

### System Organizer

Nintendo licensed A.L.S. Industries to make two types of black wooden system organizers. Both feature a plastic drawer, bearing a Nintendo 64 sticker, with slots designed to hold Nintendo 64 game cartridges, controllers, and Controller Paks.

### Traveling accessories

The Messenger Bag is a black bag to be carried on the left side of the body. It comes with zippered compartments on the outside and inside and with mesh pockets, for a few games and a controller.
Nintendo licensed a Traveling Case—a black bag, with the Nintendo 64 name stitched on the front. Two plastic buckles on the front keep the bag closed. It carries the Nintendo 64 console, controllers, games, and accessories. They also made a standard black backpack with the Nintendo 64 logo on the top and a zippered compartment on the front.

### Camera

A basic 35 mm camera, complete with a timer and flash. Official cameras have a Nintendo 64 logo on the front. They come in different colors such as blue and orange.

## Development and backup

Nintendo's original development environment for Nintendo 64 software is a card made by SGI containing most of a Nintendo 64 console, plus a software development kit (SDK) for self-hosted installation in an SGI Indy workstation.
The second generation moved to a much cheaper partner model between a normal Nintendo 64 console and a PC by providing a cartridge form factor holding flash storage with a cable connection to a PC. Nintendo officially licensed SN Systems to make the SN Systems dev kit and SN Maestro 64, the second generation of Nintendo 64 SDK in PC partner form to replace the Indy-hosted hardware solution. Unofficial kits include IS-VIEWER 64 and Partner 64. The Monegi Smart Pack is a collection of third-party hardware and software which facilitates real-time development while the game is running on the console.
Through the decades, many unlicensed third-party peripheral devices have provided many consumer-friendly alternative storage mediums for retail Nintendo 64 consoles. They bypass console security for the purpose of development or for users making backups of game cartridges and save data. The Doctor V64 is a CD-ROM peripheral designed by Bung Enterprises and released in 1996. It plugs into the Nintendo 64's underside expansion slot, and uses a lockout-bypass adaptor that fits into the cartridge port, into which any retail cartridge is inserted for use of its lockout chip by proxy. The Doctor V64 Jr. is a cheaper, condensed version that fits into the cartridge port and provides a parallel port connection to a PC. Bung made the DX 256 Super Game Saver which stores 256 battery EEPROM save states, and the DS1 Super Doctor Save Card. The CD 64 is a CD-ROM drive developed by UFO/Success Company. Mr. Backup Z64 designed by Harrison Electronics, Inc. is a ZIP drive peripheral for creating writable backups and performing playback of any Nintendo 64 cartridge. The modern Everdrive 64, ED64 Plus, N64 Neo Myth, and 64Drive use SD cards for mass storage of ROM image files or USB cables to connect to a PC for transfer.
DexDrive is a retail consumer product, an adaptor to connect a Nintendo 64 Controller Pak into a PC serial port, for sharing saved games.
