3 Pack Gamebit Security Screwdriver, 3.8mm and 4.5mm Security Screwdriver and 2.5mm Triwing Screwdriver for Super Nintendo, SNES, NES, N64 and GameBoy

My dad performed the N64 "surgery" of making it play international games of both English and Japanese and these were needed to open my system up for the "surgery". You can also check for the authenticity of the N64 games with the medium sized screwdriver. But the smallest one didn't seem to work with anything for my N64, just the biggest and medium sized one had a purpose that I know of. There is still a step farther to open up the inside of the N64 games that I couldn't open with only these screwdrivers. I liked these screwdrivers because they are the same color as my orange Japanese Pikachu N64 system.

They work. The small one wasn't really needed, but it was a good price for a set.

This Gamebit Security Screwdriver kit helped a lot. I was able to open up my N64 and NES consoles and clean them properly from the inside. Now my consoles are working slightly better and my NES is reading games a lot easier now as beforehand, I had to put my NES games in the cartridge slot a number of times before I could get a game running before I cleaned the cartridge dock. I would highly recommend this set to any retro gaming collectors who are trying to take great care of their games and consoles.
