    My emunand is on a 30GB FAT32 partition of my microSD card. When I upgraded to a larger card last week, it was quite annoying to transfer the emunand partition. I ended up using DiskGenius (Windows) to clone it sector by sector directly from the old to the new card. However, I would like to have a simple way to create a backup of the emunand in case anything ever goes wrong. I am surprised that Hekate has no emunand backup feature...
    So what is an easy way to create an image of my emunand? I don't want an image of the entire SD card, which is what for instance Win32DiskImager does.

    If you "brick" your emunand, you create easily a new one. Thats all.

    But doesn't the emunand contain the saves/list of installed games?

    If you only care about the saves, you can backup them with CheckPoint. That's how I do it. Before I update the emuMMC firmware, I create a backup of all my saves.

    So if the emunand gets corrupted for some reason and you have no backup, then you need to reinstall every game?

    Yes. But maybe if you install to the sd card, you don't have to reinstall every game.

    How is your emunand on your sd card? A hidden partition? Split files? If the latter, just back them up onto your computer. If it's a partition that's unreadable in Windows, use diskgenius and see if you can create an img of it or just back it up.

    It's a hidden partition. DiskGenius thinks it's empty and creates a tiny file that is NOT a sector by sector image (I tried this last week).
