# Game Boy Micro

The Game Boy Micro is a 32-bit handheld game console made by Nintendo. It was released in Japan on September 13, 2005, and to international markets later that year. It is a miniaturized version of the Game Boy Advance. The console was the last in the Game Boy family. Unlike its predecessors, the Micro lacks backward compatibility for original Game Boy and Game Boy Color games.

## History

According to Nintendo of America vice president George Harrison, the idea for a smaller version of the Game Boy was first discussed in 2004. Harrison explained that, unlike the traditional console development process, Nintendo was always thinking about new ideas for the Game Boy, describing it as a "continuous process of invention". Developed under the code name "Oxy", the company tried many ways to see how small they could make the Game Boy, opting for a metallic casing that, according to Nintendo Co. Ltd president Satoru Iwata, was "unusual for Nintendo".
The Game Boy Micro was announced by Nintendo of America's vice president of sales and marketing, Reggie Fils-Aimé, at the company's Electronic Entertainment Expo press conference on May 17, 2005. The system was released in Japan on September 13, 2005, in North America on September 19, 2005, in Australia on November 3, 2005, and in Europe on November 4, 2005. It was released in China as the iQue Game Boy Micro on October 1, 2005, and later released in South Korea on November 9, 2005.
The Game Boy Micro was discontinued in 2008, two years before the Game Boy Advance SP.

## Design and specifications

The Game Boy Micro retains some of the functionality of the Game Boy Advance SP but in a more compact form factor. Additionally, it has a backlit screen with the ability to adjust the brightness. The shape itself is oblong, similar to the style of the Nintendo Entertainment System controller. The Game Boy Micro features a removable, decorative housing called a faceplate. Designs with special faceplates were sold as a customization feature. Faceplates for the Micro are made using in-mould decoration.
The Game Boy Micro cannot play original Game Boy and Game Boy Color games due to design changes. While the 8-bit Sharp SM83 processor necessary to run games from older Game Boy systems is still present, it lacks other internal hardware necessary for backward compatibility. It is also incompatible with other peripherals due to its design.

## Packaging

In Japan, the Game Boy Micro was released in four different base colors: black, blue, purple, and silver. Also available at launch was a limited edition version, based on the controller of the Japanese version of the Nintendo Entertainment System, the Family Computer. In October 2005, Square Enix announced that they would be releasing a special faceplate, featuring artwork by Yoshitaka Amano, to promote their re-release of Final Fantasy IV on the Game Boy Advance. On November 17, 2005, Nintendo released a Pokémon version in Japan, featuring a red Micro with a black faceplate containing the silhouette of Pikachu. Another special edition of the Micro was released on April 20, 2006, which bundled Mother 3 with a red Micro and a themed faceplate.
In the United States and Canada, the Game Boy Micro launched with two regular color choices, each sold with three interchangeable faceplates included: silver with black, "Ammonite" and "Ladybug" faceplates; and black with silver, "Flame" and "Camouflage" faceplates. The "20th Anniversary" edition was released on December 4, 2005, which was the Famicom controller-inspired version released in Japan. In Europe, the Game Boy Micro was available in four different colors, with one matching faceplate: silver, green, blue and pink. Game Boy Micro sold in Australia have the same colors (except Green which replaced by red color) as Europe.
Aside from Nintendo of America's online store, additional faceplates were not sold in the US, and were entirely unavailable in the UK. The feature was omitted from the product's marketing, packaging, and manual in Europe.

Generally, the Game Boy Micro did not sell well, and failed to reach the company's aim of units sold. The Game Boy Micro sold over 170,000 units during its first days in Japan. According to a Q1 2007 Nintendo earnings release, 2.42 million Game Boy Micro units had been sold worldwide as of March 31, 2007, including 610,000 units in Japan, 950,000 units in the Americas, and 870,000 in other territories such as Europe and Oceania. As of July 30, 2007, the Game Boy Micro had sold 2.5 million units, according to GamePro. It was ranked #8 in their "The 10 Worst-Selling Handhelds of All Time". Satoru Iwata stated that the marketing of the Nintendo DS may have hurt the Micro in the marketplace and admitted that Game Boy Micro sales did not meet Nintendo's expectations.
The system retailed for US$99, compared to US$79 for the Game Boy Advance SP. The system was originally available in black and silver, and a red 20th Anniversary Edition was later released to commemorate the 20th anniversary of the Nintendo Entertainment System.

## Reception

The Game Boy Micro's backlit screen, which is superior to the original frontlit Game Boy Advance SP model (a later backlit remodel added a similar high quality screen to SP systems), has been praised for its visibility. Due to a finer dot pitch, the screen is more evenly lit, and the brightness is adjustable. The smaller dot pitch has also improved the apparent sharpness of the display.
The removable faceplates have also been praised because they allow for personalization and protect the high-resolution backlit screen.
