This is for when you have button compression issue on a PSP 1000. This mostly applies to when a new generic faceplate is used. I recently created a website for PSP parts, systems, and custom builds: everythingpsp....
Ive bought three different faceplates from eBay....from three different sellers. Every single one of them was scratched under the protective film! Useless quality control. Ended up buying some glass replacements as per your other video. They look fantastic 👍
