Random thought, I've been playing with the fantastic NES emulation per the Homebrew Channel on the Wii.
Since the Wii-motes are similar in style to the original NES controllers - would it be possible to play Gyromite with R.O.B. but on the Wii? I think that the NES controller A/B buttons were slightly concave and I'm not sure if the Gyros rested within that area on the buttons when playing or not (I have my R.O.B. in storage somewhere) - but interested what anyone thinks and if this might be possible?
