I got a new Sd card, can I just move all the files from my old one over and continue to use my Gateway as normal? or do I have to create a new emunand?
i berieve you need to create a new emunand, then copy it over with emunand tool or some other thing what does it.
you first have to create an emunand partition on your new SD card. You can then use emunandtool to make a backup of your "old" emunand (old SD card) and inject it into the new sd card, overwriting the new emunand.
So to create an emunand partition, I basically have to reinstall the gateway software to the 3ds or just put the launcher in the new sd and create emunand?
You can also simply copy the entire card and then resize the data partition. Here is a relevant guide: http://gbatemp.net/threads/how-to-transfer-emunand-to-another-sd-card-working-on-new3ds.383684/
Put the launcher on the new mSD, run gateway menu, format emunand, put mSD in PC, use emunand tool to iject your old emunand backup, copy over folders, profit.
