I installed 7 wads using yawmm and one of them failed. I went back to the system menu and it said that the memory was full. I moved two of my games to the sd card with the wii's sys menu data management screen. I played one of the channels on my wii and it worked fine but when I played a channel on the sd card, using the sd icon on bottom-left, it refuses to load. I try to move the the channel that didn't work back to nand but it says that my wii memory is full so, I moved the channel that worked fine(mario64) to my sd. Now none of my channels will move to my nand. It says "the data may not have been moved" or "the data may not have been copied". Does anyone know what is happening? is my nand corrupt?
