Atmosphère is a work-in-progress custom firmware for the Nintendo Switch, providing a modified boot process and system services. It consists of multiple components that replace or extend the console's original firmware layers.
Use cases
- install custom firmware on a Nintendo Switch
- run homebrew applications and games on a Switch console
- enable emulated NAND (emuNAND) for multiple system profiles
- apply system-level patches and extensions to Horizon OS
- develop and test Switch homebrew software with a modified OS
When to choose
- you need to run unsigned or homebrew software on a Nintendo Switch
- you want to customize system behavior, such as adding emuNAND support
- you are developing Switch homebrew and require a modifiable firmware environment
- you seek active community support and frequent updates for Switch firmware modifications
When to avoid
- you require a fully supported, warranty‑safe Nintendo Switch experience
- you are using the console for official online services that prohibit custom firmware
- you lack technical expertise to safely install and maintain custom firmware
