I was just wondering what the steps to actually getting Emunand was. I keep seeing stuff like EmuNand tool and such. If I want to use emunand, would I just use Format Emunand and then everytime I boot into Gateway mode its using Emunand ?
First, you'll want to copy everything from your system's SD card onto your computer. The process will involve formatting the card, which will erase everything on it.
- Enter the Gateway Launcher menu however you normally do so. (Hold L if needed to bring up the menu instead of booting Gateway Mode.)
- Select "Setup Emunand" from the menu. This will create a 1GB or so partition on your SD card to hold the emuNand, meaning your card's capacity will appear to shrink a bit. The partition is normally hidden when you view the card on the computer, because it's a format that the computer doesn't know how to read. Windows Drive Manager will show it, if you want to verify it's there, but for the most part you won't need to actually worry about it. The Gateway Launcher will then copy everything from your system's internal memory onto that partition.
- If the partition is present, booting Gateway Mode will boot that copy instead of your system's internal memory by default. Now you are running your emuNand. You do not need to use "Setup Emunand" again. Now you can copy the files back onto your SD card.
EmuNand Tool is a PC program that allows for easy backup/restore of the emuNand partition. So you should probably go ahead and back up that partition before doing anything.
After the initial setup, both nands will be using the same internal ID, and so they're "linked". They're both using the same files on the SD card, and that can cause some issues as they step on each others' toes. You can solve this by performing a "Format System Memory" on one of them, which will cause it to create a new ID. I personally would recommend doing this on sysNand, since you can do that with the card removed to prevent it from deleting any files, and so that everything you had in sysNand before is still in emuNand. I don't use my sysNand for anything other than getting to emuNand, so it doesn't make sense for me to keep any data there. You should read the available guides that list the pros and cons of linked nands, and make the decision yourself, though.
