When you open the program, you will be shown bad info.
Here's a tl;dr what they are:
R, G and B the color used for the gradient. if the color it set to 256, it will be gradient or smth.
CHANGE THING: the color to be changed: 0=R, 1=G and 2=B.
Use the D-Pad to change colors. Left and right changes the selected color, and pressing up sets the color be 256 (gradient thing or whatever)
If you press L or R, the speed changes a bit.
Notes:
Notice: Program not tested on O3DS. Yeah.
Ignore the program comments. Don't trust them.
