Wii

The Wii is the fifth internationally released home video game console released by Nintendo. The console is the direct successor to the Nintendo GameCube. Nintendo states that its console targets a broader demographic than that of Microsoft's and Sony's, but it competes with both as part of the seventh generation of video game systems, despite being noticeably underpowered compared to its rivals.

A distinguishing feature of the console is its wireless controller, the Wii Remote, which can be used as a handheld pointing device and can detect acceleration and orientation in three dimensions. Another feature is WiiConnect24, which enables it to receive messages and updates over the Internet while in standby mode. The Wii remote and Nunchuk combination can be used to play Super Smash Bros. Brawl, while the Wii Remote (turned on its side), the Classic Controller, or a GameCube controller may also be used.

Nintendo first spoke of the console at the 2004 E3 press conference and later unveiled the system at E3 2005. Satoru Iwata revealed a prototype of the controller at the September 2005 Tokyo Game Show. At E3 2006, the console won the first of several awards. By December 8, 2006, it had completed its launch in four key markets. The Financial Times reported that as of September 12, 2007, the Wii is the sales leader of its generation, based on sales figures from Enterbrain, NPD Group and GfK. The Wii sold 101.63 million units worldwide and held the title of being Nintendo's best selling home console up until 2021, where the Nintendo Switch surpassed it at 103.54 million units. The Wii also beat its contemporaries, Microsoft's Xbox 360 and Sony's PlayStation 3, both of which have sold 84 million and 87.4 million worldwide respectively.

The Wii Family Edition was released in October/November 2011. It is a cheaper version of the Wii and functions the same way as the original model, but is designed to sit only horizontally and is incompatible with Nintendo GameCube games and controllers. It was also not released in Japan and Australia. The Wii Mini was released initially in Canada on December 7th 2012. While the console can play Super Smash Bros. Brawl, it cannot play Super Smash Bros. or Super Smash Bros. Melee, as it lacks the online functionality needed to download the former, and (like the Family Edition) it lacks the GameCube controller ports and GameCube memory card slots needed to play the latter. The lack of GameCube controller ports also prevents the use of GameCube controllers with Super Smash Bros. Brawl. Though it was only available in Canada at launch, it was later released in Europe on March 22, 2013, and in the United States on November 17, 2013. Like it Family Edition, it was also not released in Japan and Australia.

In the Super Smash Bros. series
Super Smash Bros. Brawl is a Super Smash Bros. game released game for the Wii in 2008. Backwards compatibility allows for Super Smash Bros. Melee to be played on the Wii, but with GameCube controllers only. Also, Super Smash Bros. for the Nintendo 64 has been released on the Virtual Console in Japan, Europe, America and Australia for 1000 Wii Points. The Wii makes it possible, for the first time, to play all previous Smash Bros. games on the newest game's home console, as well as the first time any past Smash game has been playable on a newer console.

Some characters that debuted in games originally released for the Wii became playable fighters in the Super Smash Bros. series, all of which debuted in SSB4: Wii Fit Trainer, Rosalina & Luma, Shulk and the Miis.

In competitive play
Due to being the original hardware the game was designed for, the Wii is the preferred system to play Brawl, especially in tournaments. The game has never been re-released on another system, forcing players with physical copies to only use Wii compatible systems. While the Wii U can play Wii games by being compatible with its discs and controllers, the unintuitive nature of accessing the console's Wii mode, the native incompatibility with GameCube controllers, and the very poor sales of the console limiting its availability, makes it an unappealing option for competitive Brawl. Emulators like Dolphin also exist, but they sometimes possess bugs and performance issues not present on Wii. However, the aging hardware that is becoming progressively less reliable have forced the competitive scene to consider and experiment with these alternatives before the game becomes unplayable, and emulation developers have made great strides in making a nearly identical experience, though this niche is not quite as developed as efforts for GameCube yet.

The Wii is also commonly used to play Melee, due to its backwards compatibility with the GameCube. GameCube games played on the Wii are functionally nearly identical to those played on the original hardware, and the Wii's much greater sales compared to the GameCube make it a more readily available option for tournament setups. Later Wii models removed backwards GameCube compatibility, but these constitute a minority of Wiis in circulation, and they are rarely if ever used to play Brawl as well due to their lack of GameCube controller ports. It is additionally possible to solder GameCube controller ports onto a Wii Family Edition through hardware modding.

By contrast, the Wii is almost never used to play Smash 64, despite its availability on the Virtual Console, due to numerous emulator bugs affecting this version; as such, the competitive community always prefers playing on an original N64 console or emulators for PC, which are more reliable. As of 2019, with the closure of the Wii Shop, it is also no longer possible to legally acquire the Virtual Console version of Smash 64.

Just like how it is possible to dump Wii disc and SD card data onto other systems, some have found ways to make their own discs compatible with the Wii and download data onto SD cards. This allows pirated games, mods, and fan-games to be played on original hardware, including the many based on Brawl and Melee. In this area, the Wii has the biggest scene of any Smash game due to possessing more industry standard hardware compared to its predecessors, and the ease of defeating the console's copy protection and anti-piracy firmware to allow mods. The best known example is Project M, which would go on to have its own competitive scene that overshadowed Brawl itself before development suddenly ceased over fear of legal ramifications.
