This device is part of the LeapFrog Pollux Platform, it's recommended to start there for general information.

The Leapster Explorer (Leapfrog Enterprises)

Platform

LeapFrog Pollux Platform

The Leapster Explorer is part of 3 different devices that all share a common hardware platform, based around the Pollux SoC. The platform page contains information generic across these devices, and it is recommended that you refer to that page as it is a good starting point to understanding the Leapster Explorer, and contains some basic How To's and Tutorials to get you started.

Project Summary

The Leapster Explorer (like its predecessor the Didj) is a toy produced by Leapfrog marketed as an educational handheld gaming console for kids aged 4-9. 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.
