What Does “Custom Game Boy” Mean?

A custom Game Boy is a classic Nintendo handheld that has been modified or “modded” to enhance its functionality, appearance, or both.

Custom Game Boys can be:

  • Original Game Boy, Game Boy Color, or Game Boy Advance units with upgraded parts
  • Fully built from replacement parts without any original Nintendo hardware
  • Restored and improved original consoles

The level of customization is entirely up to you!


The Main Steps to Customizing Your Own Game Boy

Let’s break down the customization process into manageable steps:

1. Decide What You Want To Customize

Start by deciding your goals. Some options include:

  • Changing the shell or buttons to a new color or texture
  • Upgrading the screen (for better visibility or backlight)
  • Improving the sound (louder volume, better speakers)
  • Adding rechargeable batteries or new power options
  • Including features like USB-C charging or wireless audio

Make a wish list and prioritize what matters most.

2. Gather the Necessary Materials and Tools

Depending on your mods, you’ll need specific parts and some basic tools. Common materials and tools include:

Materials:

  • Replacement shell and buttons (various colors and designs are available)
  • Backlit or IPS display kit
  • New speaker(s)
  • Rechargeable battery kit or upgraded battery compartment
  • New glass or plastic screen lens
  • Custom stickers, decals, or labels

Tools:

  • Phillips and tri-wing screwdrivers
  • Soldering iron (for advanced mods)
  • Spudger or plastic opening tools
  • Tweezers
  • Precision scissors or craft knife
  • Small brush and cleaning materials

3. Disassemble the Original Game Boy

Carefully open the handheld:

  1. Remove all screws from the back of the Game Boy using the appropriate screwdriver.
  2. Separate the front and back casing.
  3. Detach the ribbon cables or connectors, noting their positioning for reassembly.
  4. Remove the main circuit board and existing components you’ll be replacing.

Take your time and be gentle. Keep all screws and parts in a labeled tray for easy reassembly.

4. Perform Your Chosen Modifications

Now, it’s time to get creative:

  • Shell Swap: Place the circuit board and buttons into the new shell, ensuring a snug fit.
  • Screen Upgrade: If installing a backlit or IPS screen, follow the instructions provided with the upgrade kit. This may involve some soldering or using adhesive pads.
  • Audio Upgrades: Remove the old speaker and solder in the replacement, checking the polarity.
  • Power Mods: Install rechargeable battery packs or upgraded battery compartments as directed.
  • Customization Details: Apply any custom stickers, button pads, or decorative lenses.

5. Reassemble and Test

Once all desired mods are complete:

  1. Carefully reconnect any ribbon cables or connectors.
  2. Place all components back into the shell, ensuring nothing is pinched or misaligned.
  3. Fasten the screws and test the device using games and accessories.
  4. Troubleshoot if anything doesn’t function as expected. Sometimes contacts or cables can come loose during assembly.

6. Show Off Your Unique Game Boy

Congratulations! You’ve created a one-of-a-kind Game Boy perfectly tailored to your style and gaming needs.
