As some of you already know, my Pokemon R/B/Y save data went corrupt (for some damn reason) and I've been trying to restore it but I heard that I might need CFW to use save managers, is that true? Am I better off using PHBankGB? Should I use my old 3DS (which is at 9.2) despite the fact that all of my VC games are on my new 3DS (which is 11.0) or will it not work?
