How to open, repair, and clean different types of video games cartridges

By using the right tool for the job!

Why you may need these tools?

• A lot of Super Nintendo (SNES) games are using lithium battery for keeping save game. Battery wont last forever,
• It is easier to open the cartridge/console to clean electrical contacts
• It is a lot easier to repair or move parts around . Especially useful for some Super Nintendo plastic that are yellow (yellowing)

I first came across these cheap and inexpensive screws head, which can be found for less than 4 €, but if wont open Game Bit screws (Nintendo NES, SNES and others)

Then I order on ebay.co.uk these 3.8 + 4.5 mm Game bit Hex Tools  for 11€ including shipping (thanks rewind.gaming)

Game Bit come in many sizes, the most popular Game Bit  sizes is the 4.5mm and 3.8mm Game Bit. But manufacturer did not only use Game Bit but also Tri-wing screws now.
