2-in-1 GameBit screwdriver: both sizes on a single handle

Opening an 8- and 16-bit generation console takes two different bits: 3.8 mm for cartridges, 4.5 mm for shells and controllers. This model brings them together on a single handle with a reversible bit: flip the tip, switch from one size to the other, and there's only one tool to keep track of.

What it does

• Two sizes, one handle: the tip flips over to switch from 3.8 mm to 4.5 mm without hunting for a second screwdriver.
• Hollow tip: the center pin of the security screw sits in the axis of the bit, which no Phillips allows.
• Solid handle: more torque than a bare bit on a bit holder, handy on a forty-year-old screw.

What it doesn't do

• Short shaft: it doesn't reach the screw recessed at the bottom of a Nintendo 64 cartridge's well. For that specific case, you need a long-shaft version.
• Does not replace a tri-wing Y screwdriver: Game Boy Advance SP, DS Lite and 3DS use a three-wing screw.
• Does not open shells closed with security Torx screws.
• Entry-level steel: the tip can round off on a seized screw if you turn before pressing down.
• Supplied without console, without cartridge and without games.

Compatibility

3.8 mm: NES, Super Nintendo, Mega Drive / Genesis, Game Boy, Game Boy Color, Game Boy Advance cartridges. The Nintendo 64 cartridge requires a long shaft.
4.5 mm: NES, Super Nintendo, Mega Drive, Nintendo 64, GameCube shells, plus the controllers and power supplies of these machines.
Does not cover tri-wing Y, Phillips or Torx screws.

Skill level

No soldering, no cutting. Seat the tip in line with the screw, press down, then unscrew slowly. For a full console teardown, also plan on a fine Phillips screwdriver and a plastic opening spudger.

In the box

• 1 × 2-in-1 security screwdriver, reversible 3.8 mm and 4.5 mm bit.
