I managed to get most of the screws out out, but I'm starting to strip the ones underneath the joy cons. I wait until the person who installed the mod chip replies to me.
This is a marvelous idea!
Side note about the screws: They are actually JIS screws, rather than Phillips. They look similar but Phillips screws are designed to cam out under force to protect the piece (and destroy the screw instead) vs a JIS which bites into the full face of the screw and will destroy the material you’re working on rather than strip the screw.
