The friend broke the R button because he was angry and hitting stuff with the 3DS because of Ridge Racer 3DS.
The things the friend has been hitting include his girlfriend, who is now pressing charges.
Nintendo won't fix it anymore because he wrote that on a note as the reason why he was sending it in again.
The R button being broken is actually key evidence in the trial against the friend for domestic abuse and is desperately seeking a discrete way to replace the button so as to discredit the note sent to Nintendo as being falsified evidence intended to frame the friend, so as to avoid being determined guilty and sentenced to jail time. Thusly, Saro is consulting B8.
