Hi everyone,
I have a Wii U with a failing eMMC, and I was already using redNAND successfully with the SD card. Everything was working normally before the SD card slot on my Wii U got damaged. Unfortunately, the slot is now completely gone, so I can’t insert an SD card anymore.
My question is: can I use a Raspberry Pi Pico by itself to boot the Wii U/redNAND without having an SD card connected to the Wii U?
If that’s not possible, I was thinking about soldering a small external microSD card adapter directly to the motherboard and using a microSD card instead of the original SD slot.
Could someone please tell me exactly which points/pins I need to solder for the SD connection? I found the Wii U SD test points (CLK, CMD, DAT0–DAT3, VDD and GND), but I’m not 100% sure which ones are required and whether CD/WP need to be connected or pulled to GND.
Basically, I want to make the external microSD adapter work exactly like the original SD slot.
Any help or a wiring diagram would be greatly appreciated. Thanks!
