About this component
The 'CPU NTR' chip carries both ARM cores and the graphics hardware. The ARM9 (about 67 MHz) runs DS games and the 3D engine; the ARM7 (about 33.5 MHz) handles sound, touch, Wi-Fi and Game Boy Advance mode. It is a custom part with no datasheet, so a faulty one can only be replaced from a donor board.
