Those of you who are purchasing the physical version of Super Smash Bros. Ultimate will need to download a patch in order to use the video recording and replay functionality without issues.
It's common practice for video games to receive a day one patch that fixes bugs and issues that were discovered after the game had gone gold and entered production.
Masahiro Sakurai's latest column in Weekly Famitsu magazine has been translated by the good folks over at Source Gaming and it has revealed information about the day one patch for the game. You can check out the full translated article here.
The day one patch for Super Smash Bros. Ultimate will automatically be applied to the digital version of the game, but those of you who are waiting on the physical version will need to download the day one patch in order for the video replay function to work.
The issue seems to be that the replays can go off-track, which suggests that Super Smash Bros. Ultimate will use the same method for recording replays that has been used since Brawl, in that it records the button inputs used during a match and uses them to recreate the match.
The input-recording method has had issues in the past, as lag or random slow down can cause a match to play out in a different manner than what originally happened.
It's possible for Super Smash Bros. Ultimate players to transfer their replays into video data, though this will take up a lot of room on the internal memory/SD card used with the system.
The day one patch will likely also come with a slew of bug fixes and changes to the balance of the game. The players who have acquired leaked copies of Super Smash Bros. Ultimate have shown different bugs during the various live streams, but these have all been physical versions of the game, which means that it's impossible to know what will be included in the day one patch until the game is released.
Super Smash Bros. Ultimate will be released for the Nintendo Switch on December 7th, 2019.
