Sonic and the Secret Rings - Catapult release

[sonic and the secret catapult]

ok so basically i'm from the future and 

in the wiimote configuration:
-tick both sideways and upright wiimote
-tilt > backward > set whatever button (in my case Trigger L)
-shake > Y & Z > set them both to the same button (in my case Trigger R)

tap both tilt and shake buttons until the catapult eventually launches sonic
