In my quest to USB C all the things, I recently USB C'd a wedge 2DS. I like this device as its nice and comfy to hold, definitely gives you the retro feeling more than the clam shell.
I used a 2 pin USB C. Some people aren't fans of this port, but for an easy beginner friendly conversion it works well. Just make sure you only use it with A to C cables.
Remove the original port (I did through sin - I clipped it with pliers by cutting the shielding, then desoldering the pins)
Pad 1 is voltage in, pad 2 is ground
With the USB C port, I clipped of the stand offs and bent the pins to be 180 degrees
Not much else to say. I used some adhesive to help hold the port in place and a file to make the hole bigger.
