Atmosphère is a customized firmware (CFW) for the Nintendo Switch, composed of components that replace and patch the console's bootloader, Secure Monitor, kernel sysmodules, and OS-level code. It enables homebrew software and system modifications on the Switch's Horizon OS.

Use cases

  • run homebrew software on a Nintendo Switch
  • install custom firmware on a Switch console
  • boot a Switch with a modified bootloader
  • use emuMMC/EmuNAND to keep a separate system environment
  • patch Horizon OS system modules for extra features

When to choose

  • you want the most widely used and actively maintained Switch custom firmware
  • you need EmuNAND support and deep system-level customization
  • you are developing Switch homebrew that relies on CFW features

When to avoid

  • you only want to run official firmware without modifications
  • you are uncomfortable with console hacking and its ban/warranty risks
  • you target other consoles than the Nintendo Switch
