Mario Kart Wii Gecko Codes, Cheats, & Hacks

Found this on WiiRD forums, can anyone try this out? I'm not sure what the QQQQ values would be...

F6000001 XXXXYYYY
ZZZZZZZZ WWWWWWWW
# use PO to do stuff here...
E0000000 00000000 # terminate everything, but DO NOT RESET PO
32000000 ZZZZZZZZ # if [po] != ZZZZZZZZ
4E00QQQQ 00000000 # reload po with address of F6 code
A8000000 FFC00001 # this is true once every 64 frames, or about 1 second @ 60 FPS
16000000 00000008 # rewrite F6 line
F6000001 XXXXYYYY # rewrite everything in case the hook moved
E0000000 80008000 # terminator and reset po
