The Nintendo Game Boy Advance was released in 2001 as the successor to the Game Boy Color. It had a massive launch title line-up of 17 games including titles such as Castlevania: Circle of the Moon, Super Mario Advance, and Tony Hawk’s Pro Skater 2. The system was also fully reverse compatible with all Game Boy and Game Boy Color games, making the total compatible library at launch well over 900 games.
In 2003 a new model of the system was released called the Game Boy Advance SP, which was redesigned to be significantly smaller with a folding design that protected the screen when closed and allowed for better portability. The GBA SP also featured a front-lit screen, the first time a Nintendo handheld had ever had a lit screen, and later would be changed to feature a true back-lit screen. In 2005 the system was redesigned again to the Game Boy Micro, which removed the Game Boy and Game Boy Color compatibility and was one of the smallest handhelds ever released.
