The Game Boy Advance SP is a Game Boy Advance with a new look for the style conscious gamer and with an internal light added for play anywhere under any condition. The SP is also rechargeable in the same way as a mobile phone.

The Game Boy Advance SP is a truly pocket-sized gadget, at only 84.6mm from front to back, 82mm wide, and an incredibly svelte 24.3mm thin. Nintendo has introduced further innovations to suit its new image, including a flip-top screen with an integrated front screen light, plus a rechargeable lithium battery similar to those found in mobile phones, offering gamers over 10 hours of continuous illuminated game-play. When the front light is turned off, the continual play increases to approximately 18 hours.

Game Boy Advance SP has the same specification as the Game Boy Advance.

All current and future Game Boy Advance games are compatible with the new system. And similarly, Game Boy Advance SP is backwards compatible, allowing use with virtually all games and accessories previously released in the Game Boy line.
