If anyone "needs it" I really don't want to know why X_X
I've never seen it used in a script, and I thought it would be funny to put it out there this way, maybe it will push someone to use it in some other script. The native function is really simple: extern void SHAKE_PAD(int padIndex, int shakeTimeMS, int shakeLevel);
The pad index is always 0, and the last parameter never goes above 256 in the decompiled scripts (somewhere around 70 there is no noticable vibration on the DS3)
