Do you want to keep all of the games on the 4GB card? If so, make a backup of your SD card, then boot emuNAND on your 3DS. Go to system settings > data management > 3DS > software and delete the games from there. After that, make another backup of your SD card. Restore the original backup to your 8GB card, and restore the SD card backup with the games deleted to the 4GB card. You'll need to inject your emuNAND backup to the 4GB card as well.Quick question. I got a 8gb card and the emunand backed up via the tool. I won't get a 16gb card for a while but I do have a 4gb available. Thing is my 8gb has games in it installed and the folder directory is all numbers it's not game.cia and just delete it. So how can I clone my 8gb to my 4gb and not copying any games over? Thanks.
