Apologies if this has already been done (I have not noticed anything) but yesterday I was over at Harbor Freight Tools (US Mainland wide chain apparently) in Everett (Washington) and they had some tri wing screw bits (I was at a Mac Tools event not so long ago where they had none). I did not grab any to try in a Wii/DS (they looked like they would fit a Wii, not so sure about a DS) but thought I would give a heads up to save people messing with online shops (some of the better chip shops lack tri wing).
