GameCube Memory Card & SD Gecko Diagrams

Post by Ashen » Sat Aug 06, 2011 12:39 pm

These are my diagrams for GC memorycard rewiring and for wiring up an SD Gecko. They go along well with my motherboard trimming guide. Thought they might prove useful to some.

GC Memorycard pinout & notes:
Pin #'s shown coincide with the pin #'s printed on top of the GC motherboard.
Image

SD Gecko pinout & signal's:
Pin #'s shown are SD card pin #'s. When wiring to GC match up signals only! INT signal is only needed on pin 9 IF you plan to make up a microSD to GC adapter as shown below. If you don't care about this feature, then the INT signal is not needed for SD Gecko operation.

GameCube motherboard pinouts & signals:
Slot A - TOP of motherboard:
Image
Slot A - BOTTOM of motherboard - Relocation points also shown:
Image
Slot B - TOP of motherboard:
Image
Image

SD Gecko (micro SD card adapter) to GC memory card slot signal's:
Again the pin #'s shown here are SD Card pin #'s. Match up the signals shown to a GC memcard slot to make up a handy adapter if you have internalized the SD Gecko slot on your portable.

Wait, so you're saying if I wire up an SD card correctly, I can use it as a GC memory card?

No, it can't be used as a regular GC memory card. You can use it to load homebrew, emulators, etc.

putting an sd gecko, you have some idea as to the sense of the slot b? How do I put the sense in sd adapter?
or is it just to make a permanent connection?

I usually just wire 3.3v to pin 1 of slot B. The GC will think something is always inserted though, which really is no big deal.

Most SD slots do have extra pins for the sense line though. So if you wanted to wire them up you could.
