The screws are called either Torx if it's star shaped or Allen if it's 6 straight sides. It's one of the most common faults on the old cartridge based consoles, dirty pins on the console or the game, nice work saving it from the dump.
Thanks for watching Roman this one was such an easy fix, I think some of the older console were built so well I don't think a ps3 would last that long 😀
