The Game Boy Micro (also called GBA Micro and stylized as GAME BOY micro or Gameboy micro) is a smaller version of the Game Boy Advance and is the third and final model of the system as well as the last model in the Game Boy line, alongside the AGS-101 version of the Game Boy Advance SP. It was released in 2005 and was discontinued in 2008.
Why It Flopped
Similar to why the Wii Mini was pointless, it was released nearly ten months after the GBA's successor, the Nintendo DS and nearly six months before the DS Lite, both of which were backwards compatible with GBA games (though that feature was removed from the DSi and later handhelds).
It was priced higher than the GBA SP despite the downgrades that it had from the original model and SP.
Backwards compatibility with the original Game Boy and Game Boy Color games was removed due to design changes.
Support for the e-reader and GameCube connectivity were removed.
The name of the system can be considered false advertising because it doesn't have the word "Advance" in it.
The small screen makes text difficult to read.
Some stores delayed the release of the system because of it being a dumb novelty.
The game link port was changed.
The design's small size makes it very uncomfortable for some gamers to use for too long.
Although it was more expensive than the SP model, it was still cheaper than all the DS and 3DS models.
It had a brighter screen than the original model and the AGS-001 version of the SP and the same brightness as the AGS-101 version.
The face plate could be swapped out for face plates with graphic designs on them.
It brought back the headphone jack, which was removed in the SP model.
