This is ONE way to mod the switch. I’ve used this process several times and I know it works. I am NOT responsible if you brick your switch. This mod is mainly for ACNH. DO NOT use pirated software with this mod. Nintendo will ban your switch. Not your account, YOUR SWITCH. You will not be able to do anything on the internet if you are banned.
Nintendo patched newer and lite switches. You can check your serial number to see if your switch is mod-able.
Some of the screen shots on this site may not look exactly like what you see on your switch/computer. As devs update their software, sometimes they make changes. Let me know if something is off.
