Everything you should know about SX OS and Atmosphere

SX OS 2.9 support Nintendo Switch 9.0 now, but from the reflection de users, this updates is not satisfied to the fans, can we use atmosphere instead of sx os to crack Nintendo Switch 9.0?

Sx os support Nintendo Switch 9.0

To install the .nsp files in the Switches with firmware 7.x and 8.x you need to update Goldleaf to version 0.5.

Warning! Not all Nintendo Switches can be hacked: check your serial number in this site 

Warning: Nintendo detects if unauthorized software has been started on the Switch and bans the console from being connected to its own servers! (you will no longer be able to play online, access eShop or update games)

The Nintendo Gaming Blog and the authors of the guides are not responsible for any damage caused to the Switch if you follow this guide

Which custom firmware to choose

Atmosphere Team Xecuter SX OS
The Switch will be banned by connecting it online. Errors: 2124-4025 and 2124-400 The Switch will be banned by connecting it online. Errors: 2124-4025 and 2124-400
FREE 25-30 Euro
Requires external devices to be started. It must be installed at every reboot (no cold-boot) Requires external devices to be started. It must be installed at every reboot (no cold-boot)
Stay active in rest mode (yes warm-boot) Stay active in rest mode (yes warm-boot)
Jigs and dongles to make starting easier, such as RCMLOADER Jig and dongle to facilitate start-up included with SX Pro
Works with any firmware (but not on all switches) Works with any firmware (but not on all switches)
Only games in .NSP format support NSP and XCI format
It is not possible to play online (ban) Play online under stealth mode
Supports emNAND / emuMMC Supports emuNAND
Supports cheats Supports cheats
Modular: possibility to add plug-ins Features that can only be added by the manufacturer = longer update times
Currently it does not support games on external hard drives, even in Dock mode In Dock mode, possibility to start .XCI or install .NSP from external hard drive 


XCI files – can mount and play XCI files direct from USB (no need to copy to SD card)
– No need to install each game, just mount and they run – just like inserting a cartridge.
– XCI files do not install tickets so *POTENTIALLY* are not as detectable as NSP files.
USB storage – NSP files can be installed to SD card direct from USB storage, no need for PC. Useful on long journeys.
EmuEMMC / emuNAND – makes it potentially possible to dodge a banned console due to no records kept in system NAND (online play under emuNAND not recommended however).
– different official firmware versions can be installed in system and emuNAND (no fuses are burned)

Not very well compatible to Switch 9.0. 
Costs money 
Cannot use KIPs advanced features – like custom kernel modules (Overclocking module, etc)
MUST use the jig and payload injector on every cold boot 


Official firmware 9.0 support and most likely ongoing support for the future.
No cost – just the included cost of your SD card for it to be installed on.
Can use KIPs advanced features – like custom kernel modules (Overclocking module, etc).
Can boot into CFW from Auto RCM – please note that auto-RCM has been extensively discussed as being potentially detectable by Nintendo and thus a bannable ‘offence’.

No XCI mounting.
No USB storage.

Keep in mind that BOTH options allow installing of NSP titles to SD card and systemNAND (or emuNAND if using SX OS) via USB cable and NUT or SX server.
Both systems allow use of homebrew and backing up save games to alternate computers / storage for safe keeping.


  • Jig: device that fits into the right Joy-Con rail to start the RCM Mode
  • Dongle: device that plugs into the USB-C port of the Switch to inject the Payloads
  • Payload: code that allows to start the custom firmware (CFW)
  • RCM Mode: start mode of the Nintendo Switch to prevent it from loading the official operating system
  • CFW: custom firmware, unofficial operating system
  • OFW: official firmware, official operating system
  • sysNAND: the primary internal memory. The OFW is installed in it but you can also start the CFW
  • emuNAND: secondary memory separate from sysNAND. Only the CFW is started in it. The supports only SX OS
  • OFW / CFW and sysNAND / emuNAND are different things: the latter are memories, “hard disks”, while the FWs are operating systems: it is possible to start the CFW both in the sysNAND and in the emuNAND while in the emuNAND it is possible to start only the CFW
  • bootloader: hekate and Briccmii are not complete CFW but programs that start before the operating system and allow the use of various additional features
  • Rom: non-original copies of the games, they exist in two formats:
  • .XCI file: non-installable files extracted from game cartridges. Only SX OS starts them
  • .NSP files: files that can be installed in the internal memory or microSD of the Switch; are games available on cartridge, in the eShop and their updates
  • .NCA file: system updates. They install with ChoiDujourNX
  • .NRO file: homebrew applications
  • root (of the microSD card): it is the main space of the memory unit (for example F: /), not a sub-folder
