Create emuMMC

Guide Information

emuMMC is a method of running CFW solely from the microSD card. emuMMC (with ban protection) creates a safe environment to do stuff that would normally get you banned, whilst retaining the ability to boot without CFW into a clean untouched sysMMC, where you can still use your Switch as if you’d never hacked it.
