===== Atmosphère =====
Atmosphère is the main custom firmware for Nintendo Switch, developed primarily by SciresM of the ReSwitched team. The name is a allusion; Atmosphère runs on top of [[Nintendo Switch#Horizon|Horizon]], referencing how the atmosphere rests on top of the horizon. Its current [https://github.com/Atmosphere-NX/Atmosphere/releases release] is 1.4.1.

===== ReiNX =====
A deprecated fork of Atmosphère, ReiNX generally does not offer exclusive features over Atmosphère itself, and has not been updated since May of 2020.

===== SXOS =====
A commercial fork of Atmosphère, SXOS is primarily developed for game piracy groups on the Nintendo Switch.

SX OS software and its modchips (which are bundled with SX OS) are illegal to manufacture, purchase, or own in the US due to multiple violations of copyright law, not limited to actions such as hardcoding Nintendo's firmware decryption keys in their software (in an attempt to avoid showing Atmosphère branding during sept, advertising and directly supporting piracy groups by supplying pirated software, and also due to failure to release source code, in violation of Atmosphère's GPLv2 license, which requires derivative works to disclose its full source code to the public.

Like ReiNX, SX OS has not been updated in years after [https://www.justice.gov/usao-wdwa/pr/two-members-notorious-videogame-piracy-group-team-xecuter-custody a successful litigation attempt] by Nintendo and the FBI, where the team was labelled as a piracy group due to directly supplementing piracy repositories within its custom firmware. Due to this, SX OS cannot even boot any recent HorizonNX releases.
