Learn how to install the Funnyplaying USB-C charging mod with audio on your Game Boy Advance SP. Step-by-step instructions, common mistakes, and tips.

Quick Answer

The Funnyplaying USB-C charging mod with audio adds a centered USB-C port and audio-out support to your GBA SP. The installation requires basic soldering and careful shell trimming. This guide walks you through each step and highlights common pitfalls.

What You Need

Before starting, gather the Funnyplaying USB-C mod kit (includes the USB-C module PCB and a spacer), a soldering iron with a fine tip, solder, flux, a small Phillips screwdriver, a plastic spudger, flush cutters, and a Dremel or small file for shell trimming. You'll also need a replacement shell if you plan to keep the original one unmodified.

The mod is compatible with most GBA SP models, but the centered USB-C port requires cutting a new opening in the shell. If you're not comfortable with permanent shell modifications, consider using a pre-cut replacement shell designed for this mod.

Installation Steps

Disassemble the GBA SP: Remove the battery and the six screws on the back shell. Carefully separate the front and back halves using a plastic spudger. Lift the motherboard out of the front shell, taking note of the ribbon cable connections. Common mistake: Forgetting to disconnect the battery first. Always remove the battery to avoid short circuits.
Desolder the Original Charging Port: Heat the solder joints on the original charging port on the motherboard. Use a solder sucker or desoldering wick to remove the old solder. Gently rock the port free with tweezers. Clean the pads with flux and fresh solder. Checkpoint: Make sure all solder is removed before pulling the port. Forcing it can lift the copper pads.
Prepare the Shell for the USB-C Port: Mark the location for the centered USB-C port on the bottom edge of the back shell. Use a Dremel or a small file to cut a rectangular opening that matches the module's bezel. Test-fit the module frequently to avoid making the hole too large. Common mistake: Cutting the hole too wide. Go slow and check fit after every few passes. A snug fit holds the port securely.
Solder the USB-C Module: Place the USB-C module onto the motherboard pads. Solder each pin carefully, ensuring no bridges between adjacent pins. Use flux to help the solder flow cleanly. Attach the spacer if included to maintain proper alignment. Checkpoint: Inspect solder joints with a magnifier. A solder bridge can cause a short or prevent charging.
Reassemble and Test: Snap the motherboard back into the front shell, route any cables, and close the back shell. Insert the battery and a USB-C cable. The charging LED should light up. Test audio by plugging in a USB-C to 3.5mm adapter or headphones with a USB-C connector. Common mistake: Not testing before fully tightening screws. If charging or audio doesn't work, open it back up and check solder joints and cable connections.
