Upon its debut, the Nintendo Switch 2 encountered some compatibility issues with first-party games, particularly when playing certain titles. To keep gamers informed about these issues, Nintendo published a list of affected games on the new console. Since then, they’ve consistently updated this list as they work to iron out persistent problems related to their first-party games on Switch 2. One significant issue involved the use of Mii Fighters in Super Smash Bros. Ultimate, which could lead to a glitch causing matches to abruptly end. However, it appears that Nintendo has recently addressed and resolved this problem.
As a gamer, I can confidently say that most Nintendo Switch games should perform even better on the upcoming Switch 2. However, Nintendo is currently tackling fresh issues that have surfaced with the new console. Just today, we received an update to squash some Switch 2 bugs related to Animal Crossing: New Horizons, as well as a console patch for both the original Switch and the Switch 2. It seems like this firmware update might also have fixed the Mii Fighter glitch in Super Smash Bros. Ultimate.
As a gamer, I’m thrilled to share that Nintendo has resolved an annoying glitch in Super Smash Bros. Ultimate on the Switch 2. Previously, online matches could abruptly end with a connection error if another Switch was in the room. This issue seems to have been addressed in the latest 20.1.5 firmware update, making our gaming experience smoother and more enjoyable! (Cheers to Polley001 for bringing this to my attention!)

According to trusted Nintendo news source @OatmealDome, Nintendo recently provided an update about the compatibility of Super Smash Bros. Ultimate with the upcoming Nintendo Switch 2.
Mii Fighters Shouldn’t Crash Matches in Super Smash Bros. Ultimate Anymore
As a devoted fan, let me point out that the recent update for Mii Fighters on Nintendo Switch primarily tackles one of the two known glitches. Although it’s undeniable that the match-ending issue is more pressing, this update doesn’t seem to be focused on resolving the problem where Mii Fighter thumbnails sometimes fail to save properly.
The memo is from June 19th, coinciding with when Switch versions 1 and 2 were updated. Nintendo often provides broad patch notes, making it difficult to determine the specific problems addressed in today’s Switch update. However, given the timing, it seems plausible that one of the “General system stability improvements to enhance user experience” addressed an issue within Super Smash Bros. Ultimate.
After resolving the issue, you’ll once more have the ability to employ the Mii Fighter in Super Smash Bros. Ultimate. Although the thumbnail saving might still experience problems, at least your games will no longer terminate unexpectedly without prior notice.
