The Game Boy Micro is the last of six in the Game Boy franchise and a redesigned (much smaller) version of the original Game Boy Advance and is the final, last Game Boy. It is much smaller than any Game Boy, including the Game Boy Pocket, but can still play all GBA games. Unlike the Game Boy Advance and Game Boy Advance SP, it does not have backwards compatibility, meaning it cannot play Game Boy Color games, or the original Game Boy games because it lacks the Z80 processor. It was designed with a very small screen and a powerful backlight. Unlike the Game Boy Advance SP, the Game Boy Micro does not have a clamshell design (similar to the original Game Boy). This makes Game Boy Advance games seem to be in HD quality, and prevents reflections on the screen's surface. Backwards compatibility with the Game Boy Color was sacrificed in order to make the Game Boy Micro smaller and more affordable. It also doesn't work with the Game Boy Advance cable link. The GBA Micro was surprisingly made a year after the original Nintendo DS, but was also discontinued before that model.

The Game Boy Micro uses its own unique charger that isn't compatible with any other Nintendo consoles and also comes with its very own faceplate unlike the older game boy models.

The Game Boy Micro never sold as well as Nintendo wanted it to, as the lack of GBA games being made was scarce and also due to the screen size dropping down to a 1 inch display.

System sales ended in 2010 ending the 21 year history of the Game Boy line.
