Is there a way I can downpatch? I noticed the older version(s) are more popular to run/faster.

If you're on digital, the only way to downgrade your version is by modding your switch.

If you're on physical, you can either mod your switch, or factory reset the switch which will bring the version down to 1.0. Afterward, if you want to update to a version like 1.1.1, but not to 1.1.2, you'll need to find a friend in person who has the version you want, and sync your version with their switch.

thanks!
