I have a 3ds XL with CFW, it's on 11.4, I think. Recently, it got a bit wet and is now broke. I bought another 3ds XL, and now want to use my old SD card on this newer 3ds. I'm going to install CFW as soon as I can, but until then, can I just take the older SD card out and put it into my functional 3ds? Or should I delete some files first, but have to put them back on during or after I install CFW?
