Guide

Note: This code makes use of user input. See this guide for reference on filling in values: https://mkwii.com/showthread.php?tid=44

XXXX = Controller Address
UUUU = Button(s) that increase gravity rapidly
DDDD = Button(s) that decrease gravity rapidly
UUUU = Button(s) that increase gravity slowly
DDDD = Button(s) that decrease gravity slowly

---

Suggested Values:

(GCN) 
UUUU = 0882 - Y + D-Pad Right
DDDD = 0881 - Y + D-Pad Left
UUUU = 0082 - D-Pad Right
DDDD = 0081 - D-Pad Left
(Wavebird GCN) 
UUUU = 0802 - Y + D-Pad Right
DDDD = 0801 - Y + D-Pad Left
UUUU = 0002 - D-Pad Right
[b]DDDD = 0001 - D-Pad Left[/b]
(Classic Controller) 
UUUU = 8020 - Y + D-Pad Right
DDDD = 0022 - Y + D-Pad Left
UUUU = 8000 - D-Pad Right
DDDD = 0002 - D-Pad Left
(Wii Remote + Nunchuck) 
UUUU = 1002 - ( - ) + D-Pad Right
DDDD = 1001 - ( - ) + D-Pad Left
UUUU = 0002 - D-Pad Right
[b]DDDD = 0001 - D-Pad Left[/b]
(Wii Wheel) 
UUUU = 1004 - ( - ) + D-Pad Down
DDDD = 1008 - ( - ) + D-Pad Up
UUUU = 0004 - D-Pad Down
[b]DDDD = 0008 - D-Pad Up[/b]
