I don't do too much with my custom firmware, but here're the specs: Old Nintendo 3DS XL (NES Edition) (United States) SysNAND version 4.2 EmuNAND version 11.0 I used the DS Profile glitch to get into RxTools version 2.6 which I use to access EmuNAND I have the SaveDataFiler.cia installed in EmuNAND and use it regularly. That's about it. My SD card with all of this is only 8GB. Let's say that I want to put everything on a bigger one (maybe 32 or 64 GB). Is it safe to simply copy over the entire SD card (all of its files on the root directory) onto a new one (that's been formatted first) and then put it directly into the 3DS? Will everything work perfectly as if I hadn't changed SD cards at all? Or will I have to set something up again? I just haven't messed around with any of this for so long that I've forgotten all of the steps to take. Now that the RXTools website launcher doesn't work anymore (launch.rxtools.net), I don't know what I would do to set it up again in case something goes horribly wrong when I switch SD cards.
