Back in 2021 I lost my house in a fire. Among the items recovered afterwards was this badly damaged ColecoVision Donkey Kong Junior cartridge. The shell had melted from the heat, and it had some trace damage, but after cleaning it in the ultrasonic cleaner I started seeing whether the electronics inside had survived.
In this video I carefully dismantle the damaged cartridge, inspect the PCB, repair broken traces using magnet wire (not pretty), test the ROM and use a completely new 3D printed replacement shell to bring it back into service.
PCBWay produced the replacement 3D printed cartridge shell used in this restoration. They are my choice for PCB production and 3D Printing services!

What started as a melted lump of plastic turned into one of the more satisfying retro gaming restorations I’ve attempted. At the end of the video I also ask whether you’d like to see me create a custom replacement label for the rebuilt cartridge.
