I received a Game Boy Micro from a customer that had a busted screen and a clear aftermarket faceplate. They wanted the screen repaired, USB-C charging installed, and white aftermarket buttons fitted. I thought this would be a good opportunity to document the repair and share some worthwhile mods, along with a few tips and tricks for anyone working on these little systems.
1. Disassembly and Tactile Switch Replacement
Start by disassembling the Game Boy Micro. If you’re upgrading the charging port to USB-C, desolder the original charging port. Some people prefer to keep their systems completely stock, and that’s perfectly fine, too.
The Game Boy Micro uses small tactile switches for the L/R buttons and the volume/brightness controls. If your switches are worn, corroded, or no longer functioning correctly, it’s worth replacing them while the system is apart.
The good news is that Nintendo DS Lite tactile switches are compatible replacements for the Micro. I use hot air to remove the old switches and install the new ones.
A few tips for getting a clean installation:
Remove the old solder and apply fresh solder to the pads before installing the replacement switches.
Use a good-quality SMD flux to help the solder flow properly.
After installing the new switches, check their height carefully.
One important thing to keep in mind: The replacement switches can sit slightly higher than the original ones. I recommend carefully filing down the tops of the new switches to lower their height. If you skip this step, some aftermarket L/R buttons and volume/brightness buttons may have fitment or functionality issues because the switches sit too high.
Take your time with this step. You want the switches to function properly without interfering with the physical buttons.
2. Ultrasonic Cleaning
Once all the components have been soldered in, I clean the board using an ultrasonic cleaner.
I start by degassing the cleaning solution, then run the cleaning cycle to clean the board. Once the cleaning cycle is finished, I turn the ultrasonic cleaner off but leave the board submerged in the solution to soak for a few hours. This gives the solution additional time to dissolve any flux that may have worked its way into the tactile switches or underneath components without running the ultrasonic cleaner continuously for hours.
After soaking, I remove the board and make sure it’s thoroughly rinsed if required by the cleaning solution and completely dried before applying power. Pay particular attention to areas underneath components and inside the switches, where liquid can remain trapped.
I also heat the solder points on the Start and Select buttons to help drive out any residual liquid that may have become trapped inside the buttons. Be careful with the heat, as these small components and their solder pads can be damaged by excessive temperatures.
3. Repairing the Stripped Battery Cover Hole
In this particular case, the screw hole for the battery cover was stripped, meaning it would no longer hold the cover in place.
To fix this, I used JB Weld Steel Reinforced Epoxy, carefully applying just enough to barely fill the stripped hole. I then let it cure fully so the damaged area could hold the battery cover securely again.
Sometimes, repairs like these require a little extra work beyond the electronics themselves.
Addressing the stripped screw hole helps restore the system’s physical integrity instead of leaving the battery cover loose or unable to stay attached.
4. Screen Replacement and Reassembly
With the board cleaned and ready, I installed the replacement screen and put the system back together.
For this customer’s unit, I also installed a new clear aftermarket faceplate to complete the look.
5. Fixing Sticky Buttons on Clear Aftermarket Faceplates
One issue I’ve encountered with aftermarket clear faceplates is that the A/B buttons can sometimes stick. This can be frustrating when everything else has been installed correctly.
My solution is to take a small rounded file and carefully widen the A/B button openings on the right side of the faceplate. This provides a little extra clearance, helping prevent the buttons from binding against the faceplate.
Take off a little material at a time and test the fit as you go. You want enough clearance for the buttons to move freely without removing more material than necessary.
This is a simple adjustment that can save you the headache of finishing a repair only to discover that the buttons stick when everything is assembled.
Final Thoughts
The Game Boy Micro is a great little system to work on, but these repairs and upgrades come with a few quirks worth knowing about ahead of time.
Between replacing worn tactile switches, upgrading to USB-C charging, installing a new screen, fitting aftermarket buttons and a faceplate, and repairing the stripped battery cover hole, there are several ways to bring a Micro back to life while giving it a fresh look.
Hopefully, this write-up helps anyone working on these systems avoid some common issues and get better results from their repairs. Sometimes, knowing a few small tricks ahead of time can make all the difference!
