Leapster Explorer

Project Summary
The Leapster Explorer (like its predecessor the Didj) is a toy produced by Leapfrog marketed as an educational handheld gaming coonsole for kids aged 5-10. Although it has a proprietary graphical front end, it runs a generic Linux distribution on the same Arm9 based processor as the Didj. Console access to the Explorer is achieved using the same method as found on the Didj.
