Hi MattR!
This one is soldered on the motherboard unfortunately.
If you have soldering experience, you can replace it!
The part can be found here: https://store.richspsxparts.com/newinwlswfor.html
If you don’t know how to solder, it’s recommend to learn this first.
You can replace the motherboard, but this will be more expensive!
Please let me know if you need any guide!
