Looking back at the game now, Super Monkey Ball: Touch & Roll's stylus controls can't compete with the level of immersion and intuitiveness we're seeing with the Wii's labyrinthine games -- Mercury Meltdown Revolution, Dewey's Adventure, and Kororinpa: Marble Mania. Thanks to homebrew hardware like the MK6-Motion and the DS Motion Card, though, we can now emulate the same motion-sensing features on our handhelds.
It's unlikely that any commercial release will ever acknowledge these unauthorized add-ons, but homebrew developers have already put out over twenty games and demos that use the data gathered from the accelerometers/gyroscope. Check past the post break for videos and screenshots of three puzzle titles that've been rigged to detect your tilting DS.
