Made a post a little while ago about horrible buzzing with my Reshell N3DSXL that I did a while back.
Simple solution was just putting some tissue paper in between the housing and the speaker. Audio volume is the same and no more buzzing. Just in case anyone else has the same issue. (Maybe some audio quality polyfil could help too but Im not spending that much just for a tiny 3ds speaker)
Either way it worked and I'm back to enjoying my ancient console.
Still need to find a replacement power board (b button that's extra force to work) and fine a replacement for my yellowing top IPS screen.
