This is interesting, there is a thread about the exact opposite, only the c stick and zl zr work, nothing else, so what do all the other inputs go through? Was this to maintain compatibility with original 3DS software?
Just got a console with these same issues, did anyone figure out if this was a solder problem? I have a donor 2DS board can I take the microcontroller from it and solder it to the nn3ds as a test?
@K3Nv2 I got some cheapies at wallys, that are pretty good, already have lost a few expensive ones (one falls out and gone, can't find) while cutting grass so bought some cheap ones, and of course never lose these cheap ones. (Cheap meaning only $35, compared to air buds which I only have 1 of 2 now)
