Archives (NTSC versions only): Two video clips are available for viewing to the player: A "How To Play" instructional video meant for newer players, and a "Special Movie", a nearly thirteen minute long video that features various gameplay modes, a roll call for the starting fifteen characters and a look at aspects of actual matches, such as Pokémon and items.
How to Play (PAL versions only): This option replaces the Archives in PAL versions of the game, due to the removal of the Special Movie; selecting this option shows the How to Play movie.

"Bonus Records" shows all the bonuses the player has attained. "Misc. Records" shows other, relatively insignificant records, such as how many VS. matches they've played.
Special: Displays the special messages that the player has attained in the game, and at what time and date.
Movies: Similar in function to Melee's "Archives" section, this menu allows players to view five already included videos and any Subspace Emissary cutscenes that they have viewed.
Records: This menu functions the same in Brawl as it does in Melee. The "Bonus Records" features, however, has been disabled, due to the lack of bonuses in Brawl. Additionally, the Notices have been moved under this menu instead, reprising their role once again.
Sound Test: Unlike the previous two games, this mode is no longer initially locked; it reprises its role from the previous two games, but the player must unlock some of the music before it is available for listening and the characters before their sound effects are available.
