Depending on your setup, there are two primary ways to ensure you are on the latest version:

: While 3DS retail cartridges were originally region-locked, many update CIA files are designated as "WORLD" or "Region Free," allowing them to be installed regardless of whether your base game is the US, European, or Japanese version.

: Fixed recurring issues that caused disconnects during Random Matchups and Online Competitions .

: Enhanced "unauthorized data-check" functions to prevent the use of cheating programs that intercept online traffic.
