Pressing R on the title screen will rotate between palettes tailored for the Game Boy Advance, Game Boy Advance SP and the Nintendo GameCube's Game Boy Player. This feature is mentioned in manualsMedia:SonicAdvance3 GBA US manual.pdf[1]Media:SonicAdvance3 GBA UK manual.pdf[2], but is not explained.

Curiously despite having a backlit screen, the Game Boy Advance SP option uses the lightest palette.
