Where to insert your tool

• Before prying up the screen, note where you need to pry:
• There's a seam between the screen and its gasket. Insert your tool here (under the screen) to give yourself the best chance of preserving the gasket.
• There's a seam between the gasket and the shell. Don't insert your tool here, or you may damage the gasket.

• When removing the screen, be careful not to damage or stretch the adhesive gasket that secures it to the shell.
• Insert the flat end of a spudger under the screen and pry the screen up. Apply constant, steady pressure to allow the screen adhesive to separate.
• If the screen isn't budging, flip your Game Boy over and lay a heated iOpener on the screen for two minutes to soften the adhesive. Alternatively, you can use a hair dryer on the Low heat setting—be careful not to overheat your device, or you may warp the plastic.

Step 17

Remove the screen

⌕

• Carefully lift the screen up and remove it.

Step 18

Disassembly complete

⌕

• Congratulations on disassembling your Game Boy! The remaining steps will show you how to transfer everything into your new shells.

Step 19

Gather your new parts

⌕

• Before starting reassembly, gather your new shells and buttons. Compare them to the original parts—you may need to remove or transfer some pieces:
• The new buttons may be connected together with small plastic sprues. If they are, break them apart and discard the plastic.
• The new shoulder buttons require the small metal arms to function smoothly. Your replacement kit may come with them, or you might have to transfer them from the original buttons.
• When installing the metal arms, make sure the arm bends inward. Optionally, you can apply one drop of superglue to the end of the arm to secure it to the button.
• Once you've prepared your new parts for reassembly, separate them from your original ones—you don't want to accidentally install old parts!

Step 20

Install the screen lens

⌕

• If your new shell has a screen lens pre‑installed, skip this step.
• Remove the adhesive backing from your replacement screen lens and firmly press it into place on your new front shell.
• Your replacement lens will likely have a protective liner on the front. To prevent scratches, leave it on until you've fully reassembled your Game Boy.

Step 21

Transfer the screen gasket

• If your new shell has a screen pre‑installed, skip the next two steps.
• You'll need a screen gasket for your new shell. If your shell comes with one pre‑installed, you can skip this step.
• If your kit doesn't have a replacement gasket, carefully remove the old one from your original shell (or screen, if it stuck to the bottom). If your kit comes with a new gasket, remove its adhesive liner.
• Use your fingers to carefully align and install the gasket in your new shell, using a spudger as necessary to hold the gasket in place and secure it.

Step 22

Install the screen

⌕

• Before installing your screen, note the following:
• If you're installing your original screen, this is a good time to gently clean it with a clean, lint‑free cloth.
• If you're installing a new screen, check for any protective liners and remove them.
• Lay your screen into its recess and firmly press around the perimeter to secure it against the adhesive gasket.

Step 23

Install the Power light

• If your kit doesn't come with the small, translucent, peg‑shaped Power light diffuser, use tweezers to remove it from your original shell (above the action buttons).
• Use tweezers to install the light diffuser in your new shell.

Step 24

Install the D‑pad and action buttons

⌕

View item

• Use tweezers or your fingers to install the action buttons (A + B) and D‑pad.
• The action buttons are keyed specifically for their recesses and proper orientation. The D-pad isn't keyed; any orientation is fine.
• The Start/Select buttons are integrated with their silicone pad—there are no plastic buttons to install.

Step 25

Install the silicone pads

⌕

• You may need to lift the shell up and off of your work surface during this step to get the silicone pads fully seated. With the shell flat, the buttons will push up on the pads.
• Use your fingers to firmly press the three silicone pads into place—one for the action buttons (A and B), D‑pad, and Start/Select buttons.
• Each pad has cutouts for alignment pegs to help properly orient them.

Step 26

Insert the motherboard

• If you're upgrading your screen or motherboard, you'll likely need to do some soldering or modifications before installing the motherboard. Reference any instructions included with your kit—and the website you purchased it from—to ensure you are properly installing everything. If this is your first time soldering, check out our helpful soldering guide.
• With one hand, hold the front shell slightly above your work surface—try to keep the shell raised until you install the motherboard screws.
• This will help allow you to fully seat the motherboard, since the buttons will push the board up if it's flat on your work surface.
• With your free hand, grip the motherboard by the cartridge reader.
• Push the motherboard into place on the shell, making sure the speaker gets correctly slotted into its circular cutout (including a small tab on the bottom).
• You may feel the board lightly click into place.
• Check around the perimeter of the board to ensure it's fully seated with no large gaps between the board and shell. If there are, gently wiggle the board and push it into place.

Step 27

Install the motherboard screws

• If your kit includes replacement screws, install them during reassembly. The screw lengths or bit sizes may vary slightly—use the quantity of each type to determine placement, keeping in mind that each set may include an extra screw.
• With one side of the shell raised, use a JIS 1 screwdriver to install the three 7 mm‑long screws securing the motherboard.
• Before continuing, make sure the board is correctly seated:
• Test the action buttons, D‑pad, and Start/Select buttons.
• Check around the perimeter of the board to ensure there are no large gaps between the board and shell.
• If the buttons feel off or there are any large gaps, loosen the screws and re‑seat the board, tighten the board, and test it again.

Step 28

Connect the screen cable

• If you're upgrading your screen or motherboard, the location of the screen cable and connector may be different.
• Before connecting the screen cable on the top edge, make sure both locking tabs are pushed up in the unlocked position.
• Use your finger to gently push the display cable into its socket on the motherboard.
• If you're having trouble, reposition the cable and try again—don't try to force it into the socket. It should slide into place with little to no effort.

• Use your fingers to install the power switch, making sure it's properly slotted around the arm on the switch mechanism.

Step 31

Install the shoulder buttons

⌕

• Since your Game Boy is laying upside down, the L button will go on your right‑hand side, and the R button will go on your left‑hand side.
• Slide the shoulder buttons into place, making sure the peg on the button goes into its circular cutout and the button shroud is over the actual button mechanism.
• Gently test the buttons to make sure they feel correct. If they don't, reposition them and make sure the metal arms aren't stuck in a weird position under the board.

Step 32

Install the side bumpers

⌕

• Use your fingers to install the side bumpers, making sure the top edges are on the outside of the shoulder buttons.

Step 33

Install the back shell

⌕

• To fully tighten these screws, it's easier to hold your Game Boy up off the work surface. Hold the two shell halves together as you work.
• Install the seven screws securing the back shell:
• Six 9.4 mm‑long tri‑point Y0 screws
• One 8.5 mm‑long JIS 1 screw
• Tighten these screws until just snug. Over-tightening can strip the screw head or damage the plastic shells.

Step 36

Install the batteries

• Use your fingers to install the batteries, following the diagram in the battery well to properly orient them.

Step 37

Step 39

You're done!

• Flip the power switch into the On position and get to gaming!
• That Game Boy startup really brings back some nostalgia…ours also somehow summoned Suction‑Cups‑For‑Feet Clampy...weird.
