Never seen something like this before. My 2016 Black Friday edition N3DS began experiencing diagonal circle pad drift, so naturally I replaced the circle pad. After doing this, it seems like only the C-Stick and ZL/ZR buttons are recognized by the OS. No sound, 3D does nothing. However, this seems to be a software issue of some sort, as all the buttons work fine in Luma and Godmode9. Anyone experience this? How can I fix it? Thanks.
