The FlipperMCE is a fully open-source GameCube memory card emulator that gives you unlimited storage for save files, auto-mounting per game, and a few tricks that even the MemCard Pro GC doesn’t offer.
Built on the same sd2psx foundation that made PlayStation 2 memory card emulation trivial, the FlipperMCE uses a Raspberry Pi Pico to handle the GameCube memory card protocol. It supports virtual cards ranging from 59 blocks all the way up to 1019 blocks, and each game’s save gets stored as a dedicated .raw file on a microSD card. No more swapping cards mid-session or deleting old saves to make room for new ones.
The hardware includes USB-C connectivity and a 0.96-inch OLED display that shows which virtual card is currently mounted. But the real standout features are the customization options: you can assign custom images to each virtual memory card and even create your own boot screen graphics. Those aren’t just cosmetic flourishes; they make navigating a library of dozens of save files actually manageable instead of a guessing game.
Functionally, it’s comparable to the MemCard Pro GC. Both use game ID detection to automatically create and mount virtual cards, and both eliminate the nightmare of juggling physical storage. The difference is philosophy: FlipperMCE is fully open-source, hardware and firmware included, so you’re working directly with save files on the SD card rather than through proprietary software.
The GitHub documentation is freely available and well-organized, and boards can be ordered from any PCB manufacturer. Macho Nacho Productions put together a full breakdown video if you want to see it in action before committing. If you’ve been holding out for an open alternative to commercial memory card solutions, this is it.
