RPIX (Read PIXel) is a Super FX instruction that loads a color from the Game Pak RAM and stores it in the destination register. It does this by first loading the color into the color matrix and converting it from PPU format.
The X coordinate is specified by R1 and the Y coordinate is specified by R2.
