Hi I am new to this, but I have done some research on the wiiu emmc chip and found that it might be possible to replace it with an SD card adapter. Because the wiiu operates in a 4bit mode when reading data from the emmc. Attached is the diagram. I am not an expert and I am open to suggestions...
@K3Nv2 I got some cheapies at wallys, that are pretty good, already have lost a few expensive ones (one falls out and gone, can't find) while cutting grass so bought some cheap ones, and of course never lose these cheap ones. (Cheap meaning only $35, compared to air buds which I only have 1 of 2 now)
