Dolphin, the GameCube and Wii emulator - Forums

No, don't do that. You should be able to use Dolphin's save export mechanism to pull out the saves you want to keep and import them into the new NAND.

Also if your NAND is really multiple years old, then yes it's quite impressive it didn't go wonky sooner.

All fine now and still 800 blocks free. Thanks for your help, guys

woops. Hm, now I'm done and it seems fine.
