I myself didn't mod the Nunchuck, I used the PS2 controller instead. How, you might ask? I used a keyboard adapter I bought once for the Gamecube, to use with PSO. This adapter also supports the DualShock. I think I used it once before.
Well, since NiGHTS can be played using the GC controller I gave it a shot and, to my surprise, it worked. So much more precise!
