ahha ive tried it before, but it sounds quite different from the real stuff

anyway instead of using LSDJ on the wii,

you could try schism tracker after you install homebrew on your wii

and also, bring your wii around is also possible

by using this 7 inch portable monitor with built-in sensors, they also have a earpiece jack output, so maybe they can be modded to play live

just a quick video showing LSDJ on the Wii.

I was surprised by the quality of the sound (not the random noises that I put in to demonstrate the concept).

It definitely sounds better than the DS emulation I've been hearing so much of recently. But yea, I appreciate that you can't take your TV and Wii on the train with you to make music.
