The Game Boy Advance (often shortened to GBA) is a handheld video game console developed, manufactured and marketed by Nintendo. It is the successor to the popular Game Boy Color. It was released in Japan on March 21, 2001; in North America on June 11, 2001; in Europe on June 22, 2001; and in China on June 8, 2004 (excluding Hong Kong). Its codename during development was Project Atlantis.

Hardware

The Game Boy Advance is backward compatible with most games previously released for the Game Boy or the Game Boy Color, as well as new software developed to take advantage of the new technical capabilities of the system. It is powered by two AA batteries, which give about 5–10 hours of play time, as well as an optional power supply that plugs directly into the Game Boy Advance's battery bracket.

Processors

The Game Boy Advance has a custom 32-bit 16.8-MHz ARM processor (ARM7TDMI) based on a RISC architecture, which is much more suited to the C programming language than the 8-bit Z80-like processor used in older Game Boy models. The ARM processor can run both 32-bit ARM and 16-bit "Thumb" instruction set encodings. The system also contains an 8.4-MHz Z80-like processor to provide support for legacy GB software; however, both processors cannot be active at the same time.

Dimensions

Length: 144.5 mm
Width: 24.5 mm
Height: 82 mm
Weight: 140 grams

Display

The 2.9" LCD is capable of a maximum of 240×160 pixels in 15-bit color (32,768 colors). This display includes more pixels than Game Boy's 160×144; when playing legacy games, the user can press the "L" or "R" button to switch the display between 160×144 with a black border and scaling to 240×144 pixels. Early games had very dark color palettes because the display in the development kits was much brighter than the one in the production units; the production display has a gamma value of 4. Newer titles use gamma correction in their palettes.

A major fault of the color LCD is the fact that the Game Boy Advance is lit by ambient light. Users quickly learned to tilt the device to take advantage of window or overhead lighting, though it still provided insufficient illumination. An aftermarket internal lighting kit known as the Afterburner^[2] was briefly popular before the introduction of the Game Boy Advance SP, and influenced the development of the new model.

Graphics

The Game Boy Advance has hardware support for simple 2D operations using graphical elements called sprites. It can scale, rotate, sum-blend, and alpha-blend sprites against a background (with one alpha value for the whole screen, not the alpha-blending of image edges seen in the PNG format), and it can change the scaling and rotation of sprites and the background on each scanline to give a pseudo-3D effect.

The Game Boy Advance's picture generator has six display modes (three tiled and three bitmap) and 96 KiB of dedicated RAM. In tiled display modes, the system can manage four pixel-to-pixel layers, two pixel-to-pixel layers and one affine layer, or two affine layers, and it uses 64 KiB of RAM for tile and map data and 32 KiB for sprite cel data. In bitmap modes, it can display one large 16-bit bitmap, two 8-bit bitmaps (with page flipping), or one small 16-bit bitmap (with page flipping), and it uses 80 KiB of RAM for bitmap data and 16 KiB for sprite cel data. In all modes, it can show up to 128 sprites (individually controllable small moving objects) of 8×8 up to 64×64 pixels in either 4-bit or 8-bit indexed color. Each sprite can be drawn using either direct pixel mapping or affine mapping; it's possible to fit more direct sprites on a scanline.

Later games pushed the Game Boy Advance to its limits with simple 3D graphics. These games include Wolfenstein 3D, Duke Nukem Advance, Doom and Doom 2. Utilizing 2D sprites for objects and 3D graphics for architecture, these games usually achieve a passable framerate, although sometimes in large environments or with many objects onscreen the framerate will drop to a very noticeable level. Some feel that such 3D games are a logical and welcome step for the Game Boy Advance, while others feel that they are overly ambitious and beyond the capabilities of the system. With the release of the Nintendo DS, future 3D games for the Game Boy Advance will most likely be limited.

Media

The interface from the Game Boy Advance unit to the ROM cartridge includes only a 24-bit address bus multiplexed with a 16-bit data bus. (Mattel's Intellivision console had previously used a multiplexed bus.) This setup limits the directly addressable memory to 16 binary megawords (that is, 256 binary mebibits or 32 binary mebibytes), but bankswitching hardware on the cartridge can extend this by controlling the ROM's upper address lines from software, effectively switching other parts of the ROM into the Game Boy Advance's address space. Using this and the cartridge maximum capacity of 32 MB, which represents half of the N64 cartridge maximum capacity, it allows the developers to add specials contents like FMVs, in games such as Kingdom Hearts: Chain of Memories.

By early 2002, hardware became readily available for moving user code onto the Game Boy Advance. For example, in December 2001, a flash memory cartridge and its writing hardware was selling for less than $200 U.S., along with a $50 device to emulate the netbooting master. By April 2003, the prices had come down to under $100 for the flash cartridge and writer and $30 for the boot cable. Because of the drop in prices for programming equipment, a homebrew software development community has sprung up. Nintendo, however, has a history of viewing such devices as nothing more than piracy tools, since they can be used to copy cartridges containing copyrighted software. In February 2002, Nintendo began sending threatening letters to some United States resellers of such devices. Previous lawsuits had banned the importation of similar devices for the 8-bit Game Boy.

Connectivity

The Game Boy Advance also has a serial port for connecting to other Game Boy Advance units in a setup similar to a token ring network over a bus physical topology. A Game Boy Advance can also receive up to 256 KiB of bootstrap code through the port, even when no cartridge is present (sometimes known as multiboot or netboot). This is used for multiplayer Game Boy Advance connections, where multiple Game Boy Advances can play with only one cartridge; one Game Boy Advance with a cartridge sends boot code to the other cartridge-less Game Boy Advances.

The serial port can (with a suitable cable) also connect to a standard RS-232 serial port for debugging purposes and (hypothetically) Internet play, although a TCP/IP stack has yet to be implemented in a Game Boy Advance game. The release of the Nintendo DS in 2004 made this further unlikely, given the built-in Wi-Fi of that system's release.

To link Game Boy Advance games, a Game Boy Advance link cable is required. To link regular GB or GB Color games, the older GB link cable is required, even if two Game Boy Advances are being used.

Nintendo also introduced connectivity between the Game Boy Advance to the GameCube console through the GameCube-Game Boy Advance cable. This function could unlock data, act as a second screen, among other things. It did not catch on very well and few games added such connectivity.

The Game Boy Advance Wireless Adapter was released on September 7, 2004 in the United States. It allows Game Boy Advances to be linked without cords, and with more than four players at a time. It came bundled with Pokémon FireRed and LeafGreen. However, a game has to be designed with the wireless adapter in mind, and there are only a few such games.

The Game Boy Micro featured another port design; in order to make the system so small, the link port was shrunken. Nintendo has released a GBM-GBM and a GBM-Game Boy Advance adapter to restore full multiplayer compatibility. Nintendo has also released a special Game Boy Micro Wireless Adapter for wireless play. These items are currently only sold on Nintendo.com.

Models

Game Boy Advance (original model)

The Game Boy Advance sold at a base price of $100 USD when it was released in North America. Prior to the release of the Game Boy Advance SP, the Game Boy Advance was the fastest-selling game console in history. Despite its success, many criticized the original Game Boy Advance for still not adopting a lighted screen, which Nintendo would rectify with later models. As of 2005, the original (non-lit) model has been discontinued.

Game Boy Advance SP

In early 2003, Nintendo upgraded the Game Boy Advance giving it an internal front-light that can be turned on or off, a rechargeable lithium ion battery, as well as a folding case approximately half the size of the Game Boy Advance. It was designed to address some common complaints with the original Game Boy Advance. Also this model of the Game Boy Advance has been critized for being very uncomfortable.

Around the same time as the release of the Game Boy Micro, Nintendo released a new backlit version of the SP in North America (commonly referred to as the GBA SP+). The switch that controls the light now toggles between "normal" (which itself is already brighter than the original Nintendo DS's screen), and "bright," an intense brightness level similar to LCD television set.

Game Boy Micro

In September 2005, Nintendo released a second redesign of the Game Boy Advance. This model, dubbed the Game Boy Micro, is similar in style to the original Game Boy Advance's horizontal orientation but is much smaller and sleeker. The Game Boy Micro also offers the user to switch between several colored faceplates to allow customization, a feature which Nintendo advertised heavily around the Game Boy Micro's launch. Unlike the previous Game Boy Advance models, Game Boy Micro does not support Game Boy or Game Boy Color titles.

Accessories

Nintendo has released many add-ons for the Game Boy Advance. These include:

Wireless Adapter - Released in 2004, this adapter hooks up to the back of the Game Boy Advance. It replaces link cables and allows many people to link up to each other. It markets for $20 and came included with Pokémon FireRed and Pokémon LeafGreen. Because it was released so late in the Game Boy Advance's life, fewer than 20 games support this hardware. The adapter's usefulness is most evident in Pokémon; FireRed/LeafGreen and Emerald feature a "Union Room" where up to forty people can enter to battle or trade Pokémon. A Game Boy Micro version has also been released - it can interact fully with both models of the Wireless Adapter.

Game Boy Advance Infra-Red Adapter - This adapter was included with the game Ciberdrive Zoids as it is only compatible with this game. The adaptor was not sold separately. This is also currently the only Game Boy Advance accessory that has not been remade for the Game Boy Micro.

Play-Yan - The Play-Yan is an MP3/MPEG4 player for the Game Boy Advance and Nintendo DS. The cartridge is slightly bigger than 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 is currently available in Japan only, but a European release has been confirmed for early 2006. Since Play-Yan did not have a U.S. release to coincide with Game Boy Micro as rumored, an American release has been speculated for 2006 as well.

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 have included 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 to have cards that unlock content. GameCube games like Animal Crossing had cards with unlockable content as well, and the Pokémon Trading Card Game playing cards also adopted the e-Reader codes. The e-Reader works with the Game Boy Player as well as the Game Boy Advance SP, but cannot fit into the Nintendo DS's Game Boy slot (it will however fit into the Nintendo DS Lite's Game Boy slot). It was discontinued in America in early 2004, but is still quite popular in Japan. It was not released in Europe.

Game Boy Advance Video - These highly popular cartridges contain two episodes of 30 minute cartoon programs. First released in America in May of 2004, they cost $19.99 and 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 and all three movies are in full. These cartridges display an error when inserted into a GameCube via a Game Boy Player. They have since decreased in popularity and can be seen being sold for as low as $4.99.

Criticism

While the Game Boy Advance was quite successful, many people believed that this version should of had some sort of internal lighting and the use of exterior lighting would not be neccessary. The problem would later turn out to be solved as all the precessor's to the Game Boy Advance (e.g. Game Boy Advance SP, Game Boy Micro, Nintendo DS) would have backlights (the first model of the SP would have a frontlight, but the second and final model would have a backlight).

Unofficial accessories

GBAMP - The GBA Movie Player is a versatile gaming cartridge that allows people to play NES/Famicom games, watch movies (e.g. MPEGs), see .txt files, hear sound clips, etc. The GBA Movie Player does not actually play MPEGS or MP3's directly, a freeware conversion software is needed, that converts an array of formats into GBM and GBS formats that are compatible with the GBA Movie Player.

Game Boy Advance TV Tuner - It makes the portable system into a portable television. There are several versions (made by different companies) available. The most popular TV Tuner requires a cartridge inserted in the Tuner to start up. The TV Tuners can store up to 99 channels.

Unofficial Game Boy Advance flash cartridges are also available. While they enable the distribution of homebrew applications and content, they may also facilitate the illegal distribution of copyrighted games.

Sales and marketing

The Game Boy Advance, along with the Game Boy Advance SP and the Game Boy Micro, has sold well. As of June 30, 2006, the Game Boy Advance series has sold 75.81 million units worldwide, of which 38.84 million are Game Boy Advance SP units, and 1.86 million are Game Boy Micro units.^[1]

Games

The Game Boy Advance has become the modern flagship of sprite-based games. With hardware superior to the Super NES it has proven that sprite-based technology could improve and live side by side with the 3D games of today's consoles. The Game Boy Advance not only has one's typical platformers, but also a huge collection of SNES-style RPGs. It has also become a popular system for old-school gamers due to the increasing amount of games ported from various 8-bit and 16-bit systems of the previous era. Through the use of flash cartridges and emulators the Game Boy Advance can even play NES and PC Engine games, as well as AGI-based Sierra On-Line PC adventure games.

Standout original titles include:

Emulators

Some of the most popular emulators for the Game Boy Advance are No$GBA, Rascal, and VisualBoyAdvance. No$GBA and Visual Boy Advance both support the loading of a BIOS image, but can run, albeit with lower compatibility, without one.

Homebrew Software Development

Many people have developed their own software to run on the Game Boy Advance. This is typically tested using emulators, and later written to flash cartridges to run on real consoles. Most such developers use a version of the GNU Compiler Collection (gcc) and program in either C or C++, though recently some developers have started using FreePascal. The most common homebrew development kits are:^[3]

devkit advance, an older kit
devkitPro/devkitARM, a newer multiconsole kit that has supplanted devkit advance
HAM Gameboy Advance Development Kit, a development kit built up around the closed-source programming library HAM

Various other development libraries are available, besides those that come with the development kits listed above. One example is SGADE, an open source software (BSD-style) library that provides a number of predeveloped functions to simplify game development.

Web sites such as gbadev.org and GBA developers provide information for such development.

Trivia

If you have a game inside the Game Boy Advance and press start and select simultaneously before the GBA chime(which is just about before the game starts),it will make another chime and you may switch one game with another,then press any other button such as 'B' the game inserted will start accordingly.
