Chosen Solution
I recently had to replace a water-damaged LCD. It went pretty well except that I stripped one of the triwing screws while putting it back together. Since that was easy enough, I decided to replace the back panel and stripped two more of the dang things. It may be me. It may be my cheap screwdriver. Either way, I’d like to know if I can get the same spec screws (length, diameter, threading) but with Phillips heads instead of triwing.
Just mind diameter, length, and thread spacing, as you stated. Unless Nintendo had those screws made in some extremely proprietary dimensions, it should work. Good luck.
It’s literally screws. It should be possible given you can find them in the correct dimensions.
