I read a lot of tutorials here, and would like to thank them for put in effort to complete guides for noobie like me. After I read a lot of walk through, I still have one question, Do I still need to put in the SD card next time I want to play a backup? Currently I am using my roommate's camera SD card, and i haven't started to put files in to downgrade my Wii yet. Can anybody shed me some light? Thank you very much.
