History and Trivia
The Game Boy Advance (often shortened to GBA) was released worldwide by Nintendo in 2001, representing a great improvement compared to previous Game Boy systems: great sound capabilities, graphics as good as the SNES one (sprite rotation and scaling effects included) and, for the first in the Game Boy system line, a widescreen display.
In early 2003, Nintendo released the Game Boy Advance SP: an upgraded Game Boy Advance with an internal front-light that can be turned on or off, and a folding case approximately half the original size. It was designed to address some common complaints with the original Game Boy Advance which was criticized for being very uncomfortable. The Game Boy Advance SP also came with a new and much brighter LCD screen for improved playability.
Finally, in September 2005, Nintendo released a second redesign of the Game Boy Advance. This model, called Game Boy Micro, is similar in style to the original Game Boy Advance's horizontal orientation, but is much smaller and sleeker. Unlike the previous Game Boy Advance models, though, Game Boy Micro is unable to support Game Boy and Game Boy Color titles.
The Game Boy Micro also allows the user an ability to switch between several colored faceplates to allow customization, a feature which Nintendo advertised heavily around the Game Boy Micro's launch.
All the Game Boy Advance systems feature no regional lockouts on software, so North American games can be played on Japanese or European hardware and viceversa. Official Accessories
* Wireless Adapter: Released in 2004, this adapter hooks up to the back of the Game Boy Advance and allows many people to link up to each other; having been released so late in the Game Boy Advance's life, only around 20 games support this hardware
* Game Boy Advance Infra-Red Adapter: This adapter was included with the game Cyberdrive Zoids, as it is only compatible with this game and the latest GBA Pokémon games.
* Play-Yan: The Play-Yan is a MP3/MPEG4 player for the Game Boy Advance and Nintendo DS. The cartridge is slightly bigger than a normal Game Boy Advance cartridge and includes a built-in headphone port as well as an SD Card slot. Music or videos that users have downloaded from the Internet can be transferred onto an SD Card and slotted into the Play-Yan device. Nintendo has released several mini games for the Play-Yan that can be downloaded from their website, although Nintendo later removed all mini-game functionality through a firmware update. The Play-Yan was initially available in Japan only, but was released in Europe as the Nintendo MP3 Player on 8 December 2006, with the MPEG4 functionality removed.
* e-Reader: The e-Reader is a rather bulky scanning device that plugs into the game cartridge slot of the Game Boy Advance. Specialized cards with codes along the side and bottom are slid through the slit, scanning the card into the Game Boy Advance. Many ideas for the e-Reader include cards that scan classic games like Donkey Kong and Excitebike onto the handheld ready to play, as well as a collaboration with Super Mario Advance 4 and Pokémon Ruby and Sapphire to have cards that unlock content. Nintendo GameCube games like Animal Crossing have cards with unlockable content as well, and the Pokémon Trading Card Game playing cards also adopt the e-Reader codes. The e-Reader works with the Game Boy Player and Game Boy Advance SP, but cannot fit into the Nintendo DS's Game Boy slot (however it can fit into the Nintendo DS Lite's Game Boy slot). It was not released in Europe.
* Game Boy Advance Video: These cartridges contain two episodes of thirty minute cartoon programs. First released in North America in May 2004, they included cartoons such as Pokémon, SpongeBob SquarePants, Sonic X, and Teenage Mutant Ninja Turtles. The movies Shrek, Shrek 2, and Shark Tale are also available for Game Boy Advance Video (due to the Game Boy Advance screen ratio, the three movies are in their widescreen format). These cartridges display an error when inserted into a GameCube via a Game Boy Player.
* Cleaning cartridge - A white cartridge that has a soft cloth inside so that it cleans the connectors of the Game Boy Advance when inserted; it can also be used to clean Slot 2 of the Nintendo DS. Unofficial Accessories
* Afterburner: The Afterburner was an internal front-lighting system which required some disassembling and soldering on the system.
* Halo Light: The Halo light was an external front-lighting system that replaced the screen protector / lens of the GBA.
* GBA Movie Player: The GBA Movie Player is a versatile gaming cartridge that allows users to play NES/Famicom games, watch movies, read .txt files, listen to sound clips, etc. The GBA Movie Player does not actually play MPEGS or MP3s directly (a freeware conversion software is needed, to convert various formats into GBM and GBS formats that are compatible with the GBA Movie Player).
* GBA TV Tuner: It makes the portable system into a portable television and there exist several versions (made by different companies) available.
* Game Shark: The Game Boy Advance version of the Game Shark was programmed only to work with Game Boy Advance games as making the device accept Game Boy Color cartridges too would have made it expensive. Codes could be entered by hand or uploaded to the device itself with the provided USB cable and software.
* Action Replay: A cheating device like the Game Shark, sold mainly in Europe. Had a few extra features as well as an updated interface.
* Action Replay MAX Duo: This was an update to the Action Replay for Game Boy Advance; not only it did function as an Action Replay, but for DS users, it could hold premade game saves or "powersaves" that could be downloaded from the Action Replay site as well as user made saves.
* Worm Cam: this device by Nyko attached to the top of the Game Boy Advance and connected into the link port of the GBA. This device functioned as a digital camera which allowed digital pictures to be taken; the snapshots could then be uploaded to a PC with the USB cable and software provided.
* DigiCam SP: This camera attachment was also made by Nyko and was essentially the Worm Cam for the Game Boy Advance SP (which could not be connected to the original Worm Cam, due to its shape).
* DataBoy: This cartridge plugs into the GBA game slot, it converts the Game Boy into an RS-232 data scope (also known as serial line monitor or protocol analyzer) and Users can play GB games, GBC games and GBA games on it.
