Memory Card Dumper for the Raspberry Pico

My PSO saves were stuck on my memory card with no way of getting them onto my PC, since I had none of the original consoles anymore.

Building on https://jamchamb.github.io/2018/12/03/gamecube-memory-card-raspi.html 's work to dump memory card traffic via Raspberry Pi, I wanted to create a simple design that can be easily produced in case anyone else still has any other save games they needed extracted.

Memcard dumper: common questions

What microcontroller does the Memcard dumper use?

The Memcard dumper is built around the RP2040, from the RP2040/RP2350 family.

How big is the Memcard dumper PCB?

The Memcard dumper measures 40 × 50 mm, has 4 copper layers and is 1.600198 mm thick.

How many components are on the Memcard dumper?

38 components, from 18 distinct parts. The full bill of materials is listed on this page.

Where can I download the Memcard dumper design files?

From the jareklupinski/memcard-dumper repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Memcard dumper design in my own project?

The repository has no license, so all rights stay with jareklupinski. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Memcard dumper without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
