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
