So I've been playing the MH4U on a good ol' 3DS 4.5 fw in GW 9.5 emunand, sadly this is a retail card so its via classic mode. Been trying a couple of things but no dice: GW classic can't run .cias ... great GW mode doesn't read retail cards - savedatafiler can't even see it? 4.5 CFW I think it sees the cart but it says broken... is it because the cart supposed to have 6.x encryption? So basically am I doomed to keep playing on the old 3DS unless there's a 9.5 CFW or something? there's no way to dump the save and convert to the new encryption and then inject back to the cart?
