Which CFW can work on Nintendo Switch 9.1.0 firmware?

Nintendo Switch 9.1.0 updated and blocked all CFW, but it won’t stop you from being on the latest FW with hacks this Christmas as two major CFWs have already been updated with support! In this article, you can know which CFW work on Switch 9.1.0 firmware.

Atmosphère 0.10.0 released with FW 9.1.0 support & numerous improvements

Unlike other releases of this very popular CFW, Atmosphère 0.10.0 isn’t considered a proper release but a pre-release so more updates are to be released expected in the near future meaning that if you only update your Switch’s FW/CFW occasionally, you might want to hold off for a bit. 

Moving on to the actual release itself, this time we have a pretty major update since Atmosphère 0.10.0 not only brings support for the latest firmware but a part of it has finished its rewriting process meaning that higher-quality code is now present in the CFW which frees up more memory for custom system modules. According to its change log, which is pretty long this time, Atmosphère 0.10.0 brings along:

• Full support for FW 9.1.0
  • It is noted that the temporary hid-mitm module will be removed in Atmosphère 0.10.1 so homebrew that wasn’t (re)compiled in the last 3 months will not accept button on FW 9.0.0+ – This means that if you’re using homebrew that’s unlikely to be recompiled with the latest libraries, either stay on Atmosphère 0.10.0 (or lower) or recompile the homebrew yourself
• The rewrite of the Stratosphere portion of the CFW, which deals with custom system modules, has been finished
  • This new code improves how IPC services are managed and is much more accurate while also being faster
• Atmosphère now uses less memory thanks to the aforementioned rewrite and this frees up an extra 10MB for custom system modules meaning that you can now run more of such modules simultaneously
• The configuration layout has received minor changes and it’s now stored in “/atmosphere/config/” alongside some renames and minor improvements
• The process override file layout has changed and this is described in the GitHub Release Page below
• Support for the configuration of overriding keys for hbl has been improved, the default amount of memory reserved for applets has been increased and some other minor features together with a whole slew of fixes for minor bugs

Without a doubt, Atmosphère 0.10.0 is an update that brings some important stuff for users of all FW versions and not only those who want to stay on the latest and greatest. However, since it’s a pre-release, waiting for another update might be wise if you only update your Switch’s hacking software every once in a while.

SX OS 2.9.3 Beta released with FW 9.1.0

If you use Team Xecuter’s offerings instead of Atmosphère as a CFW on your Switch, then you’ll be pleased to know that SX OS 2.9.3 Beta has been released. Its change log is pretty short and only states that:

• Compatibility with firmware 9.1.0

A few days ago, firmware 9.1.0 was released. While this is a minor update in terms of new functionality, we want to make sure that everyone who updated their console (or emuNAND) to 9.1.0 can still enjoy SX OS.

• Compatibility with game titles that use newer encryption

Some (very) recent games would display as white boxes in the menu and/or could not be installed. This has been resolved. Enjoy the full compatibility!

The release post mentions that Team Xecuter is still working on their promised hacking solution for ipatched, mariko (2019 extended battery life units) and the Switch Lite and stated that they will not disappoint.
