Add support for 32GB XCI files (Dragon Quest Heroes 1 and 2)
It came to our attention that 32GB XCI files were not working with SX OS. Since game compatibility is high up there on the priority list of Team Xecuter, we investigated this issue and are happy to report this has been resolved. You can now enjoy these content-packed bigger games like Dragon Quest Heroes!
Introducing Stealth Mode
Stealth Mode is our solution to prevent console bans. In SX OS v1.6 and onwards this feature will be enabled by default.

You can still disable Stealth Mode from the TX menu if you really wish to do so, however we do not recommend this (unless your Switch is already banned).
With Stealth Mode enabled your Switch system is not able to send any Switch personal information to Nintendo's servers while still allowing basic Internet functionality (for eg homebrew). Things like local WiFi play is also still possible!
Keep in mind Stealth Mode is only active when you are running SX OS! If you occasionally boot back into original Switch firmware you may expose yourself to a ban risk if you have modified your Switch system by installing NSP titles for example, so we do not recommend this!
Playing XCI titles in SX OS with Stealth Mode enabled should NOT get you banned when booting/using your original Switch firmware online. This is why we personally prefer our Game Cartridge emulation solution, and so should you!

To make for a smooth landing we have adapted your beloved SX OS to be fully compatible with the yet to be released firmware 6.0! We'll save you the fairy-tales of implied time-travel and such, but let's just say we got to have a look at this firmware a bit ahead of schedule.

We received some feedback from some expert users who are early adopters of the upcoming 6.0 firmware update. It appears we had overlooked something which made SXOS not boot firmware 6.0 for users with an exFAT formatted microSD card.

Oops. Suffice to say, we wasted no time to track down the root cause of this issue and fixed it up for you, still ahead of the official 6.0 release schedule!

Another thing which has been addressed is the incompatibility of the current "layeredFS" implementation with firmware 6.0. SX OS will now automatically disable "layeredFS" support when running on firmware 6.0, preventing any crashes/hangs.

That's it for now. We're running out of (reasonable) minor version numbers for SX OS 1… which means we are revving up for the big SX OS 2.0 release! At this point we can't spoil yet what the next iteration of SX OS has in store for you, but rest assured it will be exciting.

Again, sorry for this minor bug-fix release.

Our v1.8 release had an issue for the early adopters of firmware 6.0 where the web applet would crash. This has now been resolved!

We also have some good news for the users of the built-in FTP server: stability and speed of the FTP functionality has been improved.

One request we've been getting a lot since the start of our continuous stream of SX OS updates is a method for updating SX OS from within SX OS itself; saving you the hassle of having to swap your microSD out and into the switch all the time whenever we bring something new to the table. Good news! This will be the last time that procedure is needed!

With SX OS v1.9 we introduce our brand new "Update SX OS" functionality. This can be invoked from the menu by selecting "Update SX OS" in the "OPTIONS" tab. This will perform an OTA (Over-The-Air) update using the WiFi connection configured on your switch. If any new updates are found you will be prompted to install them. Enjoy!

EmuNAND
Lets start with the major new feature in 2.0: EmuNAND.

Those who have a background in the Nintendo 3DS hacking scene know what this is, but let's quickly elaborate for those of you who are new to the game:

The Switch uses a NAND Flash storage chip to store all of the system software, as well as your save games and other assets. With EmuNAND we create a shadow copy of this storage from which you can run SX OS. The benefits from doing this are that you keep your SX OS "world" separated from your original firmware. This also means you can keep your switch on an older firmware, while running the latest and greatest firmware inside of your EmuNAND. As we all know, older is better.. when it comes to defeating system security at least. And newer is better when it comes to enjoying the latest content!

Stability improvements
Introduction of optional beta updates available through OTA updater
— What's new in SX OS v2.1 BETA?

SX OS v2.1 beta introduces our brand new cheat engine and cheat finder. Many people requested a way to cheat in games or aid in finding cheats for games, so it has been high up on the priority list for a while. We're curious to hear your feedback about this initial version of our game cheat addition to SX OS.

As of now we don't have a big library of game cheats available yet, but we hope the community will come up with some cool ones that they will share publicly. Finding cheats and making (reliable) cheat codes for Switch games can be a laborious task and is in certain aspects a bit more involved than finding cheats for, say, a classic gameboy game!

For that reason we have written a small reference guide [HERE] for the aspiring cheat hackers out there detailing the format of our cheat codes, caveats that need to be accounted for, and small tips to bring you up to speed.

— Closing words

Go update your SX OS to v2.0.1 now by downloading the latest version from our website or using the online updater in SX OS itself. If you're feeling adventurous, give the v2.1 beta a shot, which is also available to you through the online updater in SX OS.

Docked USB drive support!
Yes. You read it right. You can now plug a USB mass storage device into your switch' dock and load XCI or install NSP content from there directly. No longer are you limited by the size of your microSD card when playing the switch from the comfort of your couch, but you can now enjoy TERABYTES of content by using external harddisks and such! The filesystem on the drive needs to be either FAT32 or exFAT, and the directories that are being scanned for content are equal to the ones you'd use on the microSD card.

Updates to the cheat system
More accurate progress indication during cheat search
People were reporting "freezes" during cheat searches, often times these were just due to impatience and a suboptimal UI from our end. The progress bars are more honest and update more frequently now!
Cheat search for exact value requires no initial dump anymore
For 'exact value' searches a big initial dump file on your microSD is not needed, and since this is often the way people start a cheat search we decided to streamline the cheat finder process a bit. You are now prompted with a question whether you want to start an exact value search or arbitrary value search, in case of the former the process will be much faster.
Automatically apply/disable cheats upon toggle
The interface for "applying" the cheats was a bit counterintuitive, you now no longer have to press the plus (+) button in order to apply cheats. They are automatically applied/disabled once you toggle them. Disabling cheats now properly works as well, so there's no need for having a dummy cheat any more to work around that limitation.
Ability to add cheats using the UI
Identifying memory locations for cheats using just the console is nice, but previously there was no way of adding an actual cheat-code for a location you found to the cheat code library. This has been addressed, and there is now an interface for doing this directly from our menu.
Show homebrew NSP icons in TX menu
Some homebrew NSP titles were not displaying their icons properly. This has been investigated and fixed.
Fix error 2345-0021 when in docked mode opening TX menu
People who play/cheat in docked mode will like this fix. The frequent crashes that happened when opening the TX menu in docked mode are now a thing of the past!

Fixed sleepmode in case of fuse mismatch
Sleep/standby mode would break when your emuNAND was on a different firmware version than your actual system NAND. This has been resolved now. So from now on you can run the latest and greatest firmware in emuNAND while at the same time keeping a lower firmware on your original system's NAND. Nifty!
Added initial support for "Internet Local Wireless Play"
Many of you have been requesting for us to add support for "local wireless play" tunneling over the internet. We have integrated this functionality into SX OS for you. This currently requires you to use a bit of software, LAN-Play on a computer to facilitate the tunneling. This software can be downloaded from the LAN-Play website: www.LAN-PLAY.com. Check out their project, they are are doing an amazing job. To enable "Internet Local Wireless Play" simply head into the SX Menu and head over to the "options" page. There's a toggle for enabling and disabling this functionality at will now.

LayeredFS compatibility fixes
It appears we introduced a regression in "LayeredFS" support in 2.5.0. This affected certain game mods like fan translations. This has been tracked down and fixed!
Improved Internet Local Wireless Play
Numerous stability fixes and improvements have been made to the Internet Local Wireless Play functionality.
Fixed false positive 'corrupted' message for installer
The Switch software management menu has an option for verifying the integrity of installed titles. When using this functionality with titles that have been installed through our NSP installer you would always get a message saying the title data is corrupt. This was mostly a false positive as the installed titles worked fine.. but we've hunted down the root cause of this and fixed this cosmetic shortcoming for all new installs!
Add support for installing XCI
You read it right, as of now you can also *install* titles that come in XCI format, just as you would be able to do for any content that comes in NSP format. This is useful for people who would like to access all of their games from the home menu screen instead of going through our menu. Of course you can still play XCI titles without installing as well!

Fixed issue with installing split XCI / NSP
Some split content file sizes were causing issues for some people, this is no longer the case!
Fixed issue with deleting files after XCI / NSP installation
Deleting the original XCI/NSP files after installation was introducing some crashes and side effects for certain users. We investigated this issue and are happy to let you know its now a thing of the past!

What was fixed?

EmuNAND 6.2 booting again after updating System NAND to 7.0
Some of you who updated their System NAND to version 7.0 notified us their EmuNAND on version 6.2 would no longer boot, thus they were unable to continue using SX OS! This of course is unacceptable, so we decided to investigate and fix it. You can now enjoy the latest firmware on your System NAND again while keeping a compatible firmware in your EmuNAND partition.
