I was thinking about putting a switch in my GCN so i could play some old JPN games i have sitting around an i noticed something odd about my GCN: R5 and R6 are swapped, i.e. R6 is occupied while R5 is not. My board revision is DOL-CPU-20, does this change how it gets wired? If so how? thanks in adva...

Check the date on your wii, make sure it's correct. I had that problem when trying it on my wii, it's date was set to 2010 instead of 2012

FAT16 is more reliable but FAT32 does work
