I've been practicing on my Wii with a GameCube controller, and I found this Gecko code:

Teleporter [Anarion]
Code:
282085EA 00000002
92210000 011A532C
92210001 011A5330
92210002 011A5334
E0000000 80008000
282085EA 00008000
94210000 011A532C
94210001 011A5330
94210002 011A5334
E0000000 80008000

Classic Controller:
Press D-Pad LEFT to save current position.
Press D-Pad RIGHT to return to saved position.
Change 28208E5A to 291AXXXX for Gamecube controller.
Gamecube controller D-Pad values:
Down - 0400
Up - 0800
Left - 0200
Right - 0100

To make it work for GC controller I tried changing the first 28208E5A to 291A0200 and the second one to 2910100 (I want to use the same buttons as Classic Controller). That didn't work, so then I tried changing both to 291A0200, but that didn't work either. What am I doing wrong?
