Team Xecuter releases its newest product-- The SX OS Custom Firmware for Nintendo Switch.

The Enterprise of Software Piracy

When sailing the high seas of software piracy, some vessels just aren't the same. While the world recently came across backup loading utilizing a tool meant to help with ROM hacks and fan translations (LayeredFS), it comes with many caveats and issues. Lots of file manipulation, low compatibility, and spotty save support make it a less than desirable means of swash-buckling, and if LayeredFS is a leaky paddle-boat, then consider SX OS the shiny new S.S. Enterprise.

The RCM payload doesn't come with it's own injector, so you'll need to use one of the already existing ones online as well as your own Jig to boot into RCM (ReCovery Mode). Since the SX OS by itself is around $25, anyone on a budget could make due by using a paperclip to do the "one-time" RCM boot and a PC whenever the console is shut off or battery is completely drained. If you are less technically inclined and have a few extra dollars, you could splurge for the SX Pro which comes with a 3D printed Jig and USB dongle that's (more or less) a plug and play solution for around $40.

One of the key features is an Auto-RCM Installation that "works on all firmwares". While I was hesitant at first, I made a full backup of my system (32+GB) and decided to bite the bullet. The installation took only a few seconds to brick my system (yes, it's supposed to do that!) so that I never needed to try jamming a paperclip into my Joycon rail ever again. The downside of this is that I will always need to be by my PC if the Switch ever turns completely off to boot it again (unless I use my phone or some other portable solution) since Auto-RCM does just that-- always boots your console into Recovery Mode from a powered-off state.

One feature I was surprised to see missing was a cartridge dumping tool. For such a nice looking and functioning product, I assumed this would have been a no-brainer. Perhaps they will add one later, but for now you will need to use another RCM payload or homebrew to dump your cartridges... or turn to more nefarious methods to acquire them.

SX OS also comes with some proprietary DRM to ensure you aren't pirating their software. The license code you get is tied to your console key remotely on their servers and is verified by SX OS via an offline activation file present on your internal SD card, so you only need to activate it once either through the game loader or by using their website if you don't want to go online; which is what I did. While SX OS will work without being activated, you are limited to only the Auto-RCM Installer, Payload Injector, and a Homebrew Launcher shortcut (Hold R while opening Album)-- a move that actually seems pretty decent on their part as non-paying customers could get some use out of the CFW without having to pay to use the backup loader.

Speaking of which, the backup loader utility runs .xci formatted dumps straight off of the internal SD card. It does this by, what I assume to be, game card slot emulation. I deduced this solely from the fact that the loader makes you remove your physical game cartridge before loading an .xci image/ROM and gives you the little game card slot picture once you return to the main menu. When you reboot or swap games, you are also left with a game tile with a "no cart" symbol on it, just like a normal cartridge. The utility is easily accessible since it replaces the Album shortcut on your Home screen and doesn't require memorizing any kind of button inputs. Of course, if you want to use the real Album for some reason, you can still open it by holding L first.

While it seems you could download game updates, play online (I haven't tried, see below), or purchase DLC with the spoofed game carts, this seems like a risky proposition since if you get banned from Nintendo's servers, you also lose access to their content delivery server (since your Switch must send console specific data to download from it, unlike the 3DS). There doesn't appear to be any cheats available in SX OS currently, but that may easily change in the future, and I suspect it won't be long before we see them added to the features list.

Danger, Will Robinson!

With the recent release of SciresM's Security Write-up, it's pretty clear that Nintendo isn't taking any chances with software piracy this time around. He has made it very clear that unless you are using LayeredFS for ROM hacks only (and not using it to, say, boot a completely different game) then Nintendo will 100% know you are up to no good. The SX OS is no exception. If you are online and launch a game backup, your system will 100% be flagged. Whether or not you will be instantly banned or hit later during a ban wave is up to Nintendo, and will be completely irrevocable.

(This is your fate if you pirate software.)

This means that you should only let the Switch go online when using original cartridges or digital game copies that you have acquired through the eShop. Any backup loaded through SX OS will technically work, but it's flagging your console to Nintendo at the same time.

And in case you were curious, at the time of writing, my Switch is on firmware 5.1.0

*UPDATE* SX Pro Dongle

attachFull132874

Review imageReview image

The SX Pro bundle comes with a very nice plastic Jig (for getting into RCM) and a dongle that boots the SX OS payload on your Switch without the need for a PC or mobile device to bring it out of RCM. From what I understand, the dongle has been ultrasonic welded shut, so it's not likely to come apart at any point (I tried, believe me). The shell has a smooth, slightly rubberized plastic that houses the whole thing and it feels pretty durable despite its light weight. The Jig isn't much more than a small chunk of plastic, but it has a nice thumb grip and fits in the rails perfectly. The jumper springs look straight and even so you shouldn't have to worry about it messing up your Joycon pins. The TX Jig jumps pins 7 and 10, for those who are curious, and their "one time use" statement implies you will only need to use it once to install Auto-RCM, if you choose to do such a thing.

The dongle has a USB-C plug on the top to connect to your switch, and a Micro USB-B on the bottom, which when plugged into the PC comes up as a device with a missing driver. I imagine this is for updating the RCM payload in the future if there is ever a need for it. For now, however, the dongle is ready to go and does not require any preparation. When I plugged it in and booted my Switch which already had SX OS license data and Auto-RCM installed, it booted right away into SX OS. I checked my memory card and it didn't appear to replace any of my license data, which means that the internal license on the dongle is still most likely un-activated and can be used to license another Switch. Typically, the SX Pro does not come with a text license key; it stores a unique key on the dongle which then activates against your Switch's console ID with TX's servers and would place the license data on your SD card.

The dongle never needs to be "charged" in a traditional sense, it can draw enough power nearly instantly from your Switch to fill the 2 internal capacitors and power itself on and send the RCM payload, which is great because you don't have to remember to keep it charged. There is a small LED that comes on when it's plugged into the PC or is booting the payload on the Switch, and once the Switch is booted you can remove the dongle and it is no longer needed until you completely power down again.

I was able to fit the dongle, cable, and Jig inside of a Switch game case-- it's a hair taller than the cart socket and it's a little snug, but I don't foresee it doing any damage to the case or the dongle. The dongle is also a bit wider than a cart, but not as tall, so if you have a carry case with mesh or flexible game cart pockets it may be possible to squeeze it in one for storage.

I tried to take some internal photos of the dongle, but I can't get the gosh darned casing apart. I've mangled some of the edges pretty good but I feel like I would have to break the shell to get it open, so instead I scoured an image off of Google and attached it. So... sorry whoever I stole it from! :P

  • Inexpensive
What We Didn't Like ...
  • No Cartridge Dump Tool
  • You WILL get banned
  • No EmuNAND

out of 10

Overall

With such a well polished and clean interface, as well as support for all modern homebrew and even third party payload launching directly from the boot-loader, there is very little to complain about. The lack of a cartridge dumper means you'll need to use a second app or turn to dirty, dirty software piracy.
Nice review!

How fast does it switch roms?
Does it only seek forward to the next game? Or can you go to the previous rom too?

In the third screenshot you can see the rom selection menu, you just pick the tile you want (I only had the one game) and press A and it loads it nearly instantly.

Interesting, but without an easy way to dump carts and no EmuNAND, SX OS is practically useless to me. I’ll still be grabbing the dongle for easy payload-loading (pay-loading, if you will), since that’s awfully convenient.

Please note: if you launch your own cartridge game in SX OS while being online, you could still be banned. Nintendo can probably see that you're running CFW while online. Maybe edit that in your post?
 
So can you "turn off" CFW and put in a real cartridge to play online without getting banned or do the switch save offline data somehow?
Also, getting banned does that mean getting banned from online play or also not being able to download game/firmware updates?

So if you want to continue play online with, let say the riginal splatoon2 cartridge for instance, you have to uninstall autorcm ? it will be safe ? If i previously launched xci games with dongle and jig there is no pb ? has SX team already tested it ? thx

You can hold Vol+ and choose to boot into regular mode instead of SX OS if you want to play online with your legit carts, no need to uninstall RCM. I just dumped my Mario Kart 8 cart and loaded it with SX OS and it used the same game tile my real cart made and had all my progress still, so no problems there, however if you are online when you launch the dumped copy it will tell Nintendo you are using a spoofed cart.

So if i play
always offline with xci games RCM + dongle + jig,
And Online only with legit cartridge in regular mode,
It will be ok ? No pb No ban ? (just to be SURE)
 
so are we fine if we play offline?

There is no way to know for sure at the moment, but as a safety precaution, only play in normal boot mode with authentic games. There is a good chance something else is detectable and gets sent the next time you go online, but only time will tell.

also curious about the ban thing, 25-30$ is pretty cheap to get access to them free warez :ph34r:

and uh, yeah id love to play the new Smash, would defintely want to purchase that off the shop, i'll even pay the yearly nintendo sub.

so @ OP i read that you stating something about holding vol+ and then you get to choose to boot into the normal system (meaning with no TX cfw applied i assume?) and this is the safe way to use your system online with your bought games yes?

if its safe that way, then im interested in their product..
but id rather get the pro version because id be afraid to keep sticking some paperclip thing in the rail of the switch.

but i think i read you saying it is only needed once ?
i dont mind having to rely on my pc/phone to send the payload to get my switch to boot into TX cfw as that is easy.
(cause i dont power off my switch that often, so that is no issue.)

but i just hope that jig stuff is needed only once like you said, and what exactly is that auto rcm?
auto recovery mode? so like you install that ARCM in order not to be forced to hold some specific button pressed upon each boot?

and while having that installed, can you still simply boot into normal system mode , and say you want to boot into cfw again you will only need to reboot (to get into rcm) then send payload thats it?

if yes, im ordering the OS version only.
 
@leonmagnus99

AFAIK AutoRCM kind of "bricks" your system so that it always goes into RCM, no need to use a Jig (probably you still need to press Vol+ though).

As it bricks your system it doesn't boot anymore at all. Even if you don't want to use CFW you would need to send the payload in order for it to boot to a menu where you select to use the original firmware.

Once autorcm is installed you dont need to hold vol+ unless you want to go to the bootloader to do a normal boot (no sx os), uninstall autorcm, or launch a third party payload/linux.

But with AutoRCM do you still need to send the payload for it to boot even the original firmware?
Or can it somehow boot the original firmware without sending a payload?

You always have to send a payload to get to the bootloader, thats why the little sx pro usb dongle is attractive to some.

makes sense, so how do you usually send the payloads?
will it work through some sort of ip thingie using an app on android?
 
A couple of questions:
1) Is it possible to charge the switch while in RCM Mode?
2) If I were to be online in normal mode with an original cartridge, can Nintendo check my micro SD card to, say, find xci files and then ban the console?

What's the practicality of emuNAND on the Switch? SD Card space is pretty pricy and lacking as is without emuNAND. Since the Switch is cracked wide open, isn't it more viable for the Switch to use NAND backups at any given point in the case of a brick? In that case, should anything happen, a NAND backup doesn't have to take up precious space on the SD card through the use of emuNAND as it can be stored anywhere elsewhere.

Agreed it sounds more like a sales pitch to why we should not use the Layered FS method and spoofing other carts.
But there are no mentions like if you were running firmware 1.0-3 and you used the SX OS will all games work or do we still need to update to the latest fimware also when you mean hold volume down during boot up does that just bypass injecting anything at all? So you are left with more of a untouched pure Switch firmware to ensure you don't get banned as easily.
They have two files a injector and the boot file is the first file just a copy of say hetake 2.3?
 
Well if it was a broken dongle, crappy software, we would know, It's a product, that you have to buy, so it has the right to review.
 
What's wrong with the review? Although judging from some threads, this thing doesn't work with the "card2" games or split files (although switching to exfat would fix this). Maybe testing of more games would have been nice.

Below a certain firmware a coldboot method is/will be available, so keeping a lower firmware could be desirable to avoid the use of a dongle, however emunand would allow for a new firmware with newer SDK libraries to run new games that come out.

You will be missing the libraries of games compiled with the newer SDK on older firmwares so they won't run on older firmware switches-- not without patches, at least. emunand could fix this issue if you have the money to purchase a large SD card since you will lose 32GB of space right off the bat. When you hold the volume at boot it gives you the image in the screenshot (the first one, very large) where you can choose to boot normally or boot into the SX OS.

I just tested 6 more games and they all work perfectly. Some over 4GB some under, I use a 128GB card with exFAT. Which Card2 games? I will test one.

They are apparently games where the partitions are different than the others. Sushi Striker is one.

OK let me go buy the game and create my totally legal single copy backup that I am entitled to by law, brb.

Edit: Nevermind, TX is aware of the situation apparently from what I can see and are making an update to fix it.

32+Gb nand back up. Is that the size we should expect, or did you just have a lot of games?
Yes. Even if you have no games, it’ll still be 28 GB of nothing in that partition. Expect it to be at least 32GB, probably more. If you want, you can not dump the user Partition (with all the games) but I remember hearing there as a downside.

The fact that they charge for it? No dumping ability? Potential bricc code? Or the fact that it's mostly stolen?
Well that's just me. But Gateway sucked, this sucks.

It costs almost nothing, game decryption/dumping is illegal sir ;), and of course it has brick code (how do you think AutoRCM works?). Politics, rumors, and jealous rage aside, I try to review everything unbiased as a self contained product and compare it to what else is currently on the market and currently it deserves a 9. It's a third of the price of an actual game and does everything better than anything else out there at the moment. It lost a point for no cart dumper, though...
 
i got the sx os version..
worth it imo.
it will def come in handy, fun to play with the payload stuff, it was not fun harassin my switch with the foil method, but was worth it, installed autorcm.

and tx unlike gw does not crash/hang and whatnot..
backup loading is instant.

this is good stuff , i just hope they release an update to have an option to zoom out the tiles in the albums backup interface!
(not that i have to much installed, have around 10 titles only installed, but itd be very nice to have something like the 3ds where you can zoom out of tiles and see more.)

and lastly, i hope there will be something like FBI soon, because playing Xeno2 with english dub is kiling me inside out.
its too darn awful, i will hold out a while before getting into it... need the jap audio dlc :l
 
so you need to use that usb everytime you want play ? or its one time only and than you use switch without any "additional" accesories ?

only when powering up the switch. after that, you can use sleep mode and keep your battery charged. you dont need to insert the dongle each time you load a game, just upon reboot of the switch.
 
"so it's not likely to come apart at any point (I tried, believe me)."
well did you try a dremel?
lots of things are ultrasonic welded shut (my BMW key , amazon dash buttons as an example)
really wanted to see inside , those photos are just mockups , i think they are from TX themselves
 
Since the last update ( 1.2) when i add a game, in the game library, there is a picture for the game, and a blank picture with the file name of the game. How to fix that and remove this blank picture ?

there are OS X files (normally it remove them when i eject my uSD :P )

Yeah they are from TX, and ya I jammed a tiny flathead anywhere that looked like I could wedge it in and the plastic would start to crush with zero give in the shell around the point of impact. You would really have to destroy the housing to get inside it, I think... I didn't want to damage mine beyond repair to try lol...

That can't be right. Pin 1 and 4 are GND and 5V (which would be bad.) You were probably looking at it from the wrong side and it's actually 7 and 10.
