Brain Age isn't the most enjoyable of DS games played straight. Playing it through an emulator that lets you substitute answers for stupid doodles sure fixes that.

This "speed run" isn't terribly fast - indeed, it'd be faster writing the actual answers - but it's way more fun, as by using an emulator they're able to substitute proper answers for pictures, which by mimicking the game's means of detecting stylus strokes tricks it into thinking they're the actual answers.
