Dug out my PS1 the other day and discovered that one of my two memory cards have stopped working.
Thankfully PicoMemcard is a thing :3

Started working on it this morning. After cutting down the old, dead, PS1 memory card PCB I was able to fit the RP2040-Zero, and MicroSD reader, inside the case.
Next is soldering all the cables, programming the RP2040-Zero, and then final fitting :3
