Game Boy Advance

The original GBA was the first Nintendo handheld to switch to a widescreen format, using a 3:2 aspect ratio. The color screen is not backlit. It also added shoulder buttons to the normal Game Boy layout. It is fully backward compatible with Game Boy and Game Boy Color games.


The first Game Boy Advance SP was model AGS-001. It added an internal frontlight, brighter screen, and came with a rechargeable battery. It also featured a clamshell design.

Around the time the Micro was launched, Nintendo introduced the AGS-101 model. This model introduced a backlit screen.


The Micro features a backlit screen but ditched the clamshell design of the SP in favor of a much smaller horizontal layout reminiscent of the original GBA. It is not compatible with Game Boy or Game Boy Color games.
