Another USB C tutorial. This time: the GBA SP.
Now, this has already been done by many. Makho has a vid using BlindEye's board to help the process.
However, I have a stack of six pin USB C female ports on hand always and wired it up manually.
Follow Makho's guide to remove the original charge port. Use the pictures bellow as a guide for the pinout. You only need to use one positive pad and one negative on the USB C port.
I used Makho's cad from Thingiverse as a bracket for the USB C port, held with a few drops of glue.
*** I recommend using USB A - C chargers only with this mod
