Static save files do not require an entry in the save data indexer to mount. Prior to 17.0.0, save data files were considered static if userid was 0. In 17.0.0+, only 8000000000000000 is static. However, some users using cfw do not have an entry for 8000000000000120 in the indexer, for various reasons (but mostly manual nand-restore, I think). Thus, on boot of 17.0.0+, FS will say 8000000000000120 is not present (not in indexer), and NCM will create it anew. The 8000000000000120 save will then be empty, and then the firmware can't boot. To workaround this, logic has been re-enabled on 17.0.0+ for building the content meta database. Thus, if the user encounters this error, the 8000000000000120 save will be emptied, but then it will be automatically reconstructed, fixing the problem. |

Atmosphère is a work-in-progress customized firmware for the Nintendo Switch.
Components
Atmosphère consists of multiple components, each of which replaces/modifies a different component of the system:
- Fusée: First-stage Loader, responsible for loading and validating stage 2 (custom TrustZone) plus package2 (Kernel/FIRM sysmodules), and patching them as needed. This replaces all functionality normally in Package1loader/NX Bootloader.
- Sept: Payload used to enable support for runtime key derivation on 7.0.0.
- Exosphère: Customized TrustZone, to run a customized Secure Monitor
- Thermosphère: EL2 EmuNAND support, i.e. backing up and using virtualized/redirected NAND images
- Stratosphère: Custom Sysmodule(s), both Rosalina style to extend the kernel/provide new features, and of the loader reimplementation style to hook important system actions
- Troposphère: Application-level Horizon OS patches, used to implement desirable CFW features
