How would i go about emulating this game?

leapster emulation at the moment is currently impossible. funny thing is the leapster is made entirely of adobe flash, theres just a small percentage of stuff that isnt flash so it wont work in the vanilla flash player, and nobody has really bothered trying. good news is leapster tvs are pretty cheap so if you have a capture card you'll be good to go

Thanks a ton! After some digging around i found that MAME can emulate the leapster, though very terribly.
