Of the various regional versions of the Chronicle sub-mode, the Japanese list is the closest to a complete list of games published by Nintendo up to December 2007.

However, various old webpages on Nintendo of Japan's website that similarly compile all Nintendo-published games for a particular console list some games that were not in the Chronicle:

• The Super Famicom page includes several games that were released exclusively through the Nintendo Power service (not to be confused with the North American magazine of the same name) and never received a standard physical release.
Additionally, all games in the Chronicle that were originally released for the Nintendo Power service would use their release dates for their standard physical release (e.g. Fire Emblem: Thracia 776 was first released via Nintendo Power on September 1, 1999, then released on cartridge on January 21, 2000; the Chronicle uses the latter release date for the game).

• The Game Boy page includes another Nintendo Power-exclusive, Balloon Fight GB, the Japanese Game Boy Color release of Balloon Kid.
Oddly, Super Mario Bros. Deluxe, despite being a Nintendo Power-exclusive title in Japan, is still listed in the Japanese Chronicle.

• The Nintendo 64 page includes games by Rare not based on pre-existing properties (both Banjo-Kazooie games for the system, Blast Corps, Jet Force Gemini, and Perfect Dark), three Star Wars titles (Star Wars: Shadows of the Empire, Star Wars: Episode I - Racer, and Star Wars: Rogue Squadron) and F-1 World Grand Prix.

• The Game Boy Advance page includes Oriental Blue: Ao no Tengai.
Additionally, while Nintendo has published every game in the Famicom Mini series (known as Classic NES Series in North America and NES Classics in Europe), only the ports of first-party titles were included in the Chronicle.
The 2005 re-release of Famicom Mini: Super Mario Bros. was also excluded from the Chronicle, likely due to that version simply being a re-release to commemorate the 20th anniversary of the original Super Mario Bros.

• The GameCube page includes Final Fantasy Crystal Chronicles and Baten Kaitos Origins.

• The Nintendo DS list includes the Nintendo DS Digital TV Tuner peripheral.

• The Virtual Boy and pre-2008 Wii webpages have completely identical game lists to their Chronicle counterparts.

As of Super Smash Bros. Ultimate in 2018, only three characters that started out as Assist Trophies became playable in future installments:

•Little Mac, an Assist Trophy in Brawl, then became playable in Super Smash Bros. for 3DS/Wii U
•Dark Samus, an Assist Trophy in Super Smash Bros. for 3DS/Wii U, then became playable in Ultimate
•Isabelle, an Assist Trophy in Super Smash Bros. for 3DS/Wii U, then became playable in Ultimate.

In 2023, a webpage on Nintendo of Japan's website was created to celebrate the 40th anniversary of the Family Computer. One of the subpages is a list of nearly every game published by Nintendo for the system, including those released exclusively for the Disk System peripheral. The only other known official list of Nintendo-published Famicom games available is the Chronicle in the Japanese version of Super Smash Bros. Brawl.

However, the Famicom 40th Anniversary subpage omits several games that were included in Brawl's Chronicle. These include:
• Popeye, as well as its spin-off titled Popeye no Eigo Asobi, likely due to licensing issues with King Features.
• Spartan X (released as Kung Fu outside of Japan), likely due to the game being a license, as it is based on the movie Wheels on Meals.
• Miho Nakayama's Tokimeki High School, likely due to the game heavily featuring real-life Japanese idol, Miho Nakayama.
• Ginga no Sannin, a port of the home computer game The Earth Fighter Rayieza by Enix. It is not known why this game was excluded from the list.
• All re-releases of standard Famicom games for the Disk System (such as Super Mario Bros., Tennis, and Mahjong). The Famicom cartridge re-release of The Legend of Zelda is also omitted.

In addition to these omissions, while the Chronicle lists Mike Tyson's Punch-Out!!, the Famicom 40th Anniversary subpage instead lists the original Gold Version released exclusively in Japan, which did not include Mike Tyson.

In the Japanese version, two games featured in the Nintendo Chronicle list are Jump Super Stars and Jump Ultimate Stars, a duology of Smash Bros.-styled fighting games released for the Nintendo DS that serve as crossovers between several Shonen Jump properties. Coincidentally, both games feature Goku from the Dragon Ball series, a highly-requested non-gaming character for the Smash Bros. series.

Super Smash Bros Brawl was Samus's first appearence that featured voice acting, as Zero Suit Samus has several spoken taunts. Before this, only three games had had her say any lines: Super Metroid, Metroid Fusion, and Metroid: Zero Mission; these lines were only in text format and were unspoken.

There is an extensive amount of music that is listed within the game's data, but the tracks themselves are not present in the final version.

There are multiple glitches that can occur if a character begins their Final Smash as the bridge is reforming in the stage 'Bridge of Eldin". The most notable of these is that R.O.B. will enter his final smash, Diffusion Beam, and stay in that state for the rest of the match, no matter how long. He will also remain invincible.

With enough damage, it is possible to "destroy" a Landmaster, forcing the final smash to end early. However, without hacking, it is extremely difficult to pull off.

An unused subaction and corresponding animation exist for Zero Suit Samus' Plasma Whip Side-B, labelled "SpecialSItemGet". There are also two other unused throwing animations for Samus labeled as "SpecialSThrowS" and "SpecialSThrowHi".

Presumably, the attack would originally have grabbed items from a distance and slung them away as a projectile, a function that would have been unique to the character. It may have been removed due to it interfering when players were attempting to hit another player with the whip.

The Announcer (who also voices crazy hand and master hand) is Pat Cashman, who was the announcer for "Bill Nye, The Science Guy". He even acted in some scenes in the show.

During the Subspace Emissary, Ike will shout "Great Aether!" before attacking the Ancient Minister in a cutscene. However, the attack he does is merely a normal Aether.

This may have been done to match the pacing of the Japanese version, where he says "ten" as he leaps into the air, and "kuu" as he swings his sword down.

Sakurai considered making Miis Playable, but decided against it. According to Sakurai, it didn't seem right at the time to have Miis punching and kicking. Miis were however added in the game's sequel six years later.

The only three English voice actors from Star Fox Assault's western dub to reprise their respective roles in Super Smash Bros. Brawl's Lylat Cruise conversations were:

•Jim Walker as Fox McCloud
•Alesia Glidewell as Krystal
•Mike McAuliffe as Slippy Toad

All the other characters were recasted:

•Falco Lombardi, now voiced by Dex Manley (originally Mike Madeoy)
•Wolf O'Donnell, now voiced by Jay Ward (originally Grant Goodeve)
•Peppy Hare, also now voiced by Dex Manley (originally Henry Dardenne)
•Leon Powalski, now voiced by Jim Walker (originally David Scully)
•Panther Caroso, now voiced by Eric Newsome (also originally David Scully)

This is not the case in the Japanese version of Super Smash Bros. Brawl, where literally of the Japanese voice cast from Assault, that also heavily comprised of returning voice actors from Star Fox 64, reprised their roles. More specifically, Kenji Nojima, Hisao Egawa, Kyoko Tongu, Tomohisa Aso, Teiya Ichiryusai, Mahito Ōba, Shinobu Satouchi and Tetsu Inada reprising their roles Fox, Falco, Peppy, Slippy, Krystal, Wolf, Leon and Panther respectively.

An unused graphic of the Mario icon from Super Smash Bros. Melee can be found in the game's files. The Mario icon could mean that all the icons were going to be reused from Melee, but it also could have simply been a placeholder graphic.

There is unused tile for the Stage Builder which can't be used normally. It resembles a bump, and is fully functional.

The track "Castle / Boss Fortress (Super Mario World / SMB 3)" was originally going to be in the Delfino Plaza stage, but was later moved to the Luigi's Mansion stage instead.

Masahiro Sakurai stated that the Villager from Animal Crossing was removed from Brawl during the planning stages because "he wasn't suited for battle".

Using a camera hack in the Pokemon Stadium stage, it's possible to see a hidden building with the word "Pocket" written on it. This is the first word in "Pocket Monsters", the Japanese name for Pokemon.

This appears to be the Saffron City stage from the original Smash Bros.

There's is an unused enemy called Mizzo which is never found in the Subspace emissary except during the enemy display room inside the Halberd. It appears to be an orb with arms and legs sticking out, surrounded by wind. However, a trophy exists for this enemy which will spawn randomly wherever trophies can spawn. The trophy description references this enemy's absence.

The Japanese release exclusively includes a 5-minute demo of Mother 2 (known as EarthBound in West) and a 3-minute demo of "Fire Emblem: Monsho no Nazo" within the Masterpieces menu.
