Today's the big day! Atmosphère, the Nintendo Switch CFW made by @SciresM and his team, has reached a new milestone, thus marking the release of version 0.9.0!

A few improvements were made to creport and dmnt's cheat virtual machine, adding more detailed output and 32-bit game support for the former and a new debug opcode for the latter, however, most users will be excited to know that a highly anticipated feature has finally been included: we're talking about emuMMC, of course! This has been possible thanks to a collaboration between @SciresM, @_hexkyz_, @m4xw and @CTCaer and it's the first publicly available free and open source implementation of NAND redirection for the Switch. Atmosphère's emuMMC can be enabled by editing the file emummc\emummc.ini and setting "emummc_enabled" under its relative section to 1. The feature is able to redirect reads and writes to either a separate partition on the card (recommended) or loose files in a directory with the archive bit set: in order to choose one of the two, you have to set either "emummc_sector" or "emummc_path" to a valid value (read the changelog for more information). By default, emuMMC will use a different Nintendo folder called "Nintendo_<emummc_id>", however, you can choose whichever directory you like by setting "emummc_nintendo_path" to your desired one.

While the current implementation is in a working state, the developers stress it should still be considered an experimental feature; as such, users who want to set emuMMC as their main boot option are advised to wait until any eventual bugs are fixed in the next update. Some planned features are also currently not included, for example having a separate atmosphere folder for each emuMMC.

The official changelog is as follows:

0.9.0 is Atmosphère's eighteenth official release.

fusee-primary was last updated in: 0.9.0.

With thanks to the @switchbrew team, Atmosphère 0.9.0 is bundled with hbl 2.1, and hbmenu 3.0.1.

The following was changed since the last release:

• Creport output was improved significantly.
  • Thread names are now dumped on crash in addition to 0x100 of TLS from each thread.
    • This significantly aids debugging efforts for crashes.
  • Support was added for 32-bit stackframes, so reports can now be generated for 32-bit games.
• dmnt's Cheat VM was extended to add a new debug opcode.
• With thanks to/collaboration with @m4xw and @CTCaer, support was added for redirecting NAND to the SD card (emummc).
  • Please note, this support is very much beta/experimental.
    • It is quite likely we have not identified all bugs -- those will be fixed as they are reported over the next few days/weeks.
    • In addition, some niceties (e.g. having a separate Atmosphere folder per emummc instance) still need some thought put in before they can be implemented in a way that makes everyone happy.
    • If you are not an advanced user, you may wish to think about waiting for the inevitable 0.9.1 bugfix update before using emummc as your default boot option.
      • You may especially wish to consider waiting if you are using Atmosphere on a unit with the RCM bug patched.
  • Emummc is managed by editing the emummc section of "emummc/emummc.ini".
    • To enable emummc, set emummc!emummc_enabled = 1.
  • Support is included for redirecting NAND to a partition on the SD card.
    • This can be done by setting emummc!emummc_sector to the start sector of your partition (e.g., emummc_sector = 0x1A010000).
  • Support is also included for redirecting NAND to a collection of loose files on the SD card.
    • This can be done by setting emummc!emummc_path to the folder (with archive bit set) containing the NAND boot partitions' files "boot0" and "boot1", and the raw NAND image files "00", "01", "02", etc. (single "00" file with the whole NAND image requires exFAT mode while multipart NAND can be used in both exFAT and FAT32 modes).
  • The Nintendo contents directory can be redirected arbitrarily.
    • By default, it will be redirected to emummc/Nintendo_XXXX, where XXXX is the hexadecimal representation of the emummc's ID.
      • The current emummc ID may be selected by changing emummc!emummc_id in emummc.ini.
    • This can be set to any arbitrary directory by setting emummc!emummc_nintendo_path.
  • To create a backup usable for emummc, users may use tools provided by the hekate project.
  • If, when using emummc, you encounter a bug, please be sure to report it -- that's the only way we can fix it.
• General system stability improvements to enhance the user's experience.

For information on the featureset supported by 0.9.0, please see the official release notes.

A reminder for people new to Switch hacking: emuNAND/emuMMC will not help if your console is banned, has been flagged by Nintendo or if your NAND has been "tainted" by running CFW/homebrew and you don't have a clean backup. All currently available implementations are preventive measures which let you have a clean system partition that you can use with your legit games online (no homebrew or game backups) and another separate one (the emuNAND/emuMMC itself) on which you can run everything else offline without fearing a ban. The latter is created from a copy of your Switch's internal memory: as such it will not let you evade a ban, nor clear any modifications or error logs made by homebrew apps.

This^

If there are any "shills" on this board, they're all from Atmos users, trying to say how SX "sucks" or are baselessly stating "facts" (note the quotes...) and are using mental gymnastics to reason as to why SX is "terrible", and it's really not. it's just another CFW. They have immature hatred because It's paid. It's the same reason Gateway was getting shat on, even though they had features, too, that Luma didn't have. It's literally all just immaturity coming from literally only Atmos users. Those children need to get over it.

I truly don't understand it. My friends who use atmos are understanding as to why me and others use SX. And my SX friends are understanding as to why they use Atmos. My SX friends and myself understand why they use Atmos as their primary, and they understand why myself, along with my other friends use SX as their primary. The difference between those people and the children on this board...? They actually ACCEPT and UNDERSTAND with MATURITY that SX has some amazing features that Atmos doesn't, and likewise, that Atmos is free and there's reason to use that over SX. Seriously. Any rational mature person can see this. If they try to argue otherwise, they're childish and are coming from a place of bias and hate. They immediately go on my "shit list" as trolls.

I don't see this as some sort of "winning game", or that "one MUST be better than the other". For some reason, many here just baselessly bash SX, and it comes from a place of immaturity and bias. It's silly. Just be okay with the fact that SX has features that Atmos doesn't, and that there's reason to use it, and be okay with the fact that Atmos is free, and there's reason to use that.

Literally. It comes down to preference. And whether you like it or not, there IS reason to use SX over Atmos, just as to others, there IS reason to use Atmos over SX.

To the children, who try and bash SX, really... grow up. I literally mean that. If you're trying to argue that "SX sucks", you immediately lose all credibliity for your opinions in my mind. You don't post facts, you use your mental gymnatstics in an attempt to justify your own bias. Freaking stop. This is seriously exhausting. Just let people use what they want...

Alright, I'll bite for once. I don't hate SX OS because it's paid. I don't give a damn about that. If you make something and you think it's worth selling, put a price on it. That's on you, not on me and I'm not the one trying to tell you that you should work for free.

I hate SX OS because it actively steals code from FOSS projects (primarily Atmosphere) without following the proper licenses for FOSS (this is a flat out fact you can't deny. People have decrypted and poked at the decompiled source code and found that it's taking a lot of FOSS licenses) and a lot of the things it does on it's own are often done incompetently which cause weird bugs that people wouldn't be getting if they just used the FOSS projects they steal code from or use similar implementations.

Maybe you don't care about copyright or FOSS, but some people do and that causes a lashing out from people who do care about the scene itself and the ability to make cool things. Stealing FOSS code without following the license is a slap in the face of developers as their work and credit is stripped from the product itself, just so that an illegal business can make money. Tolerating that behavior drives developers who might want to make cool stuff away from the scene as they cannot rely on the fact that somebody will not steal their code.

Capiche?

 

[THYPLEX]

Xci bans you even if you dump your own.
I still think xci is still needed.
I only use dumps of my own cards in xci format. I dislike nsp. This format plainly sux.
Atmosphere is nice but sxos is nice too. Both in one would be the best.

Both in separate are just "okay"
Cheats and xci from sxos in atmosphere and that cfw would be golden.

I m glad that Emunand finally arrived. I have no use of it sadly as my ofw is too high to make any good use out of it. Still good for all the ones that need it though

So finally i can use an emunand, and in doing so , avoiding the ban of my official nand ?

 

[bjaxx87]

Please correct me if I'm wrong, but emuMMC won't be much of help to use my hacked Switch online, right?

I have a 100% clean NAND backup but restoring it would get me back to FW v4.1.0.

So to play online I'd be forced to update my SysNAND either manually using ChoiDujourNX (which means it won't be clean anymore and that there's a high risk of ban) or legally (which means fuses will be burnt and... the Switch will be patched unhackable?).

So how exactly should I be able to play online using my clean NAND backup?

The whole TX steals code thing is a moot point, people who use SX use it mainly for piracy so a bit of stolen code means squat. And as it goes I bet most Atmos users also have piracy as their main use for it so again how many of them actually care about a few lines of text being stolen. I for one don’t give two shits

In fact I think it’s funny that people argue over some stolen text in a forum where piracy is rife and has been for at least the last 4 or 5 Nintendo systems, it just hides under the moniker of “homebrew”.
I know for a fact that GBAtemp has always been my first port of call for enabling “homebrew” on any of my Nintendo systems

From my understanding, EmuMMC (or EmuNAND, take your pick) is what you use to play run and play your backups/homebrew offline while retaining a clean NAND internally that can play cartridges/purchased content online.

Again, from my understanding, if you have an iPatched unit, updating your sysNAND to the latest version renders it unhackable. However, if you have one that is not patched, then you can "safely" keep your sysNAND on the latest version while having the rest of your homebrew locked up tight in the emuNAND, running whatever version you want.

I think you are going to restore your NAND backup and update to the latest version of Switch OS (8.0.1 i think).
But I think in this process we are going to lose something, like the savegames of our games, because they are on the Atmosphere nand.

 

[bjaxx87]

Yeah, I get that. But how can you use your clean NAND without updating it? I don't think there's a "safe" method to legally update your SysNAND without burning fuses.

 

[m4xw]

Hope ya'all have fun

 

[eyeliner]

I have my clean Nand backup, with boot0 and boot1. Can I merge the files and then just use etcher to make a partition and test, or is there something more involved missing?

 

[pcwizard7]

how do i setup the ini file for multiple emunands?

So your only argument is "stolen code", when you're using atmosphere to steal games? Nice logic. The amount of childish bias on this board is nuts!

Not to mention, Gateway apparently had "stolen code" too. This keeps happening. I dont think its farfetched to say that dev's probably sell their code to tx, or are even part of tx. I'd say that's highly likely with how often code gets "stolen". And of course they wouldn't admit it because then they'd get into legal trouble. Although that's all conjecture at this point.

Your argument is really weak, and your hate is unjustified. Especially due to the fact that you use atmosphere to pirate games, as well. You cant bash one company for something, if you're doing that exact same thing. That's double standard.

The sx hate here is ridiculous, and the amount of circle-jerking fanboys here is insane...

Open up your mind and stop hating something just to hate it. You and your bandwagon biased fanboys are horribly obnoxious.

If you like atmos fine. But having options is a good thing. Just let everyone enjoy what they want.

 

[almmiron]

I'm a common user and I don't play any games online. Maybe if I decide to play online games, i'm gonna try this emummc. But, i'm updating atmosphere anyways. This thing will be the sxos killer, indeed. Like 3ds-gateway got killed

 

[pcwizard7]

atmos will never add hdd support since you can't load nsp only install to the sd card and that's something sxos will always so lets drop it plz

 

[FoxMcloud5655]

Yeah, I get that. But how can you use your clean NAND without updating it? I don't think there's a "safe" method to legally update your SysNAND without burning fuses.

Forgive me if I'm wrong, but this is all, again, from my understanding; I don't have experience doing this. You can use memloader.bin to open up your sysNAND, back it up, update it, then reupload the copied backup onto your Switch. From there, just run hekate as normal and always boot into stock firmware. As long as you always boot from hekate and never boot using the standard boot module (without AutoRCM or anything), your fuses shouldn't ever burn, and you can still downgrade.

 

[g4jek8j54]

I must say that the double standard on these forums is quite baffling.

On an SX thread all rightful criticism gets stifled and told to go to other threads, whereas on the Atmosphere threads, SX shills happily prance on how SX is so much better than Atmosphere.

Just an observation.

GBATemp where are you guys this has been offtopic for pages now and why is there so much hate on the forums, people attack you for asking a question, give a opinion or small comment and makes me want to comment less

we need to make this forum a community again so plz we need a dhange

I'll respond this one time (I usually just report the off-topic posts)...this website is a joke sometimes. I have reported several of these idiots to the moderators, and nothing has been done about it, except one post being removed. I don't care if Team-Xecuter fanboys/shills want to circle-jerk with each other about how superior SX OS is to Atmosphere (odd, since it uses/steals Atmosphere code), but it shouldn't be allowed in this thread, since it is off-topic. They can go do it in a different thread. And before anyone says anything, SX OS uses Atmosphere code, so discussion of Atmosphere in their threads is, sadly, not off-topic. I also don't believe that known thieves who once included brick code in their "software" deserve the same considerations, anyway, but that's just my opinion.

They have immature hatred because It's paid.

I always find it amusing that SX OS fanboys often resort to this "they are just jealous because they can't afford it" nonsense, when the majority of its userbase uses it to steal games, so they don't have to pay for them.

And no, I actually buy the games that I want, and I have no interest in using Atmosphere for piracy purposes.

If they try to argue otherwise, they're childish and are coming from a place of bias and hate. They immediately go on my "shit list" as trolls.

I've noticed that Team-Xecuter fanboys like to use the term "hate" a lot. Like there is anything wrong with "hating" Team-Xecuter's garbage "product"...

By the way, you need to get over yourself. Nobody on this site cares if you consider their opinion credible or not, or whether or not you consider them to be trolls.

 

[toxic9]

SXOS have "this" incredible feature.. Atmos have "that" incredible feature..
There will always be an advantage over the other... the most important imo, is being free. So, SX lost the fight from the beginning.

I think we should not forget that there are still important thins to work on.
Like to make CFW work on all Switch models, and also become permanent.

Just LOL, Atmos is as much a piracy tool as any other CFW on any other system. Stolen code is a moot point when most users using wither Switch CFW are using it to play STOLEN games. I use both Atmos and SX for their differnet reasons but mainly SX due to being able to play a large library of games from USB hdd without any installing.

SXOS have "this" incredible feature.. Atmos have "that" incredible feature..
There will always be an advantage over the other... the most important imo, is being free. So, SX lost the fight from the beginning.

We always used to pay for modchips in years gone by, why does it have to be free nowadays?

You know all those roms you use on your beloved homebrew Emulators, they were mostly ripped years ago using PAID FOR techniques such as cartridge copiers or modchips.
Nowadays all you twats want everything for free, i mean for fucks sake are free games not enough?? Are you that tight that you can only pay for the console and then never spend another penny on anything for it??

Apologies for the language but geeeeeez, some people are so self entitled.

 

[Ev1l0rd]

Except it doesn't come preloaded with the relevant patches.

That mere fact makes this statement of yours an utter joke as it is made clear by that that the intent is not to enable piracy.

We always used to pay for modchips in years gone by, why does it have to be free nowadays?

Because times fucking change. Welcome to the fucking present where your old concept of "we have to buy a flashcard or solder a modchip" is the past tense since consoles are ran on actual OSes now which can contain bugs we can exploit.

Secondly, those modchips actually cost materials to manufacture. Exploiting systems these days doesn't take materials, it just takes some time and someone dedicated to finding bugs. It's an entirely different situation.

Also, it's funny that your lot doesn't seem to understand the sheer irony of paying so you can play free games. But I digress.

I really hit a nerve with you didn't i??

1st.. It takes a matter of seconds to find a build of Atmos ready to go fully piracy enabled. I stand by what i said because im willing to bet the majority of Atmos users are using a piracy enabled version for playing pirated games

2ns.. I obviously dont mind things being free, my point was why is the most important thing that they are free? That what the guy i was replying to said!!

Tbh i miss the old days as having to actually open your console and do a bit of soldering etc required a little patience and skill and kept away most of the self entitled noobs and idiots because it was too difficult for them. And yes i see you irony but hey i paid less than the price of one game for SX and i have access to every game available for hat one payment. Not a bad deal at all in my book and if Atmos had been first i probably wouldn't have bothered with SX. It wasnt, so i did and i dont regret it

What? When did I ever say, "They are jealous because they can't afford it"? That comment is so ridiculous; as ridiculous and silly and immature as your arguments, and holds no weight in the same vein of things. That just proves to me how immature you are regarding this situation, mate. And also, I'm not an SX fanboy. I prefer SX, but as I stated, I use both. I'm talking against the silly arguments that very biased atmos users tend to spout.

Take a look at what you've just posted, and look how you LITERALLY posted nothing. No points, just "They use the term 'hate' so they're wrong herrrr". You literally made ZERO points, which add ANYTHING to your argument. You just came at it , 100% from a place of bias an childishness.

You do realize that all of your "points" are absolute garbage and hold no weight...? If you're going to call SX users "fanboys" or "trolls", then actually try backing up your points with facts. You've failed to do this, and again, like the others here, you've joined the group of "salty biased troll whos' just spouting hate just to hate". You have no points toward your argument, and yet, the ones who support SX have actually given solid points.

You look really stupid. I'd suggest you stop arguing and trying to act as though you're in the right, when you can't even argue your point with logic and maturity. Thanks.

Just let everyone use what cfw they want, and stop being so damn stupid about it. You're acting incredibly childish with bias. If you like atmos, use atmos. I'll continue using SX, primarily. But if you're going to try and argue, at LEAST do so with ACTUAL facts and ACTUAL points rather than "SX SUCKS HeRRRRP" because it doesn't. It literally does everything that Atmos can do AND MORE. You're literally getting salty and are just arguing due to your own immature bias. That's on YOU. And YOU are part of the problem on this forum. YOU are a toxic member with your bias-fueled arguments, mate. YOU are what's wrong with this forum. You bring fights, in an attempt to bring hate on something by listing points that aren't actually even "points". You might not like what SX "stands for", in some sense, but you cannot deny that it still has actual reason to be used, and that there are a LOT of people who actually prefer it to atmos. Don't let your immaturity and bias get in the way.


But I really don't have the energy to argue with someone who can't even argue rationally, when they know they're in the wrong. Your bias is consuming your argument, and your argument holds no weight. You're not very smart and you're not worth my time. Done.

Now unless you drop the bias, I don't want to hear any more about this from you. It's clear you simply cannot argue, and are just arguing due to your bias, with no real points to your claim. Now let's get back on topic and stop spouting this daft stupidity.
