Hacking Leapster Explorer

Was looking online today to try to get rid of some stupid ads that leapfrog installs onto their leapster explorer system, that we got for my 4yr old for christmas... anyway, i came across this ability to possibly hack the darn thing so it can run a GBA emulator and subsequent GBA games.. but there's no real explanation on how to do so.. anyone programming savvy that would know how to do this task?
