Awesome thanks. Is there a recommended minimum class/speed? Is a Class 10 one sufficient? What's the minimum read speed I should be looking at?
It doesn't seem to matter beyond a certain class. I tried it with the card that came with the 3DSXL which is a class 4 I think and got no stutters. I couldn't tell any difference in performance between it and my 128GB class 10; Gamecube isos load very quickly.
