    I think this deserves its own thread. Thanks to the guys at Switchbrew it's been discovered that firmware 5.0 adds compatibility with an unannounced Switch revision with the codename "Mariko".


    The only thing we know is that the revision will use Tegra 214 instead of the current 210.

    The CPU upgrade is probably because the current Switch SoC (system on a chip) includes a hardware vulnerability that makes hacking possible in all firmware versions, even future ones.

    We don't know how different this revision would be. It could be a simple security upgrade or a new model a la new 3DS.

    Either way, this means future Switch units will have a different SoC and current ones will probably become rare (and more expensive because of the hacking possibilities).

    Update 03/19/2018:

    This may be bigger than we originally thought.

    Another Switch hacker replied that the 8GB bump may be for the devkits only for now, but these devkits may be related to a new Switch revision.


    It's also convenient to remember what Nintendo said about revisions last year:

    So that means that current Switch users are in the clear if they ever want to install homebrew on their consoles?

    Being an early adopter pays off sometimes!

    Kinda. It means that the bootloader on those Switches are always vunerable, and can be tricked into loading and running any code and not just Nintendo-signed code. Actually getting it code to load is where the issue is now.
  6. Banamy


    Yes in time, don't update if you want it.
  7. udllpn


    Does this mean a hardware revision is on the horizon, or a new SoC doesn't really have anything to do with it?
  8. gcwy


    I don't think there will be a performance upgrade, not a significant one, at least. I could be wrong.
  9. KRBM


    The current SoC contains a vulnerability that may lead to a Switch jailbreak in the future. The new SoC is likely designed solely to close this vulnerability.
  10. Jawbreaker


    Welp. I'm glad I have a Switch already.
  11. Pokemaniac


    Unless we get more info indicating otherwise, this is most likely only going to have security vulnerabilities fixed.
  12. Iichter


    That leaves a lot of vulnerable bootroms for the Nintendo Switch.
  13. Thoraxes


    Just new guts that are the same as the old but with the loophole closed, maybe better power efficiency or reduced hardware footprint to cut on costs for them to increase profit.

    No hardware revision like a new model or anything.
  14. Anteo


    Haha yeah. Id still buy a new swiych before trying tho

    that super rare item with only over 10 million made!

    The switch is finally going to be worth the price tag i paid for soon.
  17. Apopheniac


    How do you stop updates on the Switch? Does it require disconnecting from the Internet completely, or is it just update prompts like on the 3DS?
  18. Iichter



    You are not completely disconnected but you don't have access to eshop anymore I think.
  19. http://switch.cfw.guide/guide/blocking-updates/ - just change DNS settings to manual pretty much. However, this does limit all internet as far as I know but I haven't tested going online. For me it's fine because I always play single player games anyway (until Smash comes out later this year).

    I’d be curious what else this new SOC is packing since I doubt they’ve got any 20nm lines still pumping out X1s.

    Current Switches use the Tegra 210 CPU.
    New ones will use Tegra 214.

    There's a mention of a new SoC with the codename Mariko.

    There's even a different folder for it's data. Current model uses the "nx" folder while the new one "a" folder.
  22. delete12345


    I wondered if there is any insignificant differences between T210 and T214, with the exception that one is flawed more than the other?

    What I'm assuming is T214 is slower than T210 because there are more additional checks made securely.
  23. Farrac


    Thanks for the info, guys.
  24. Bishop89


    I'll be glad to pick this up when smash, Pokémon and advance wars releases on it!
  25. maximumzero


    Sounds like the many motherboard revisions the Xbox 360 silently went through, this this happens with every console and handheld ever.
  26. 7upguy


    If Nintendo silently switched to a 16nm process wouldn't people notice because some Switches would have way more battery life?
  27. ShadowFox08


    Tegra x2 gives up to double the power performance also in it's highest performance mode. They can't just do that without an official revision
  28. Ikaruga


    Maybe 3-5 years down the road. -Or never.
  29. JordanKZ


    The idea of having to produce a new SoC to patch a security hole is kinda nuts. Still, this probably helps to justify the new major build number, even if it didn't really do anything for end users. But, between this and the new security changes, there's been some major internal changes.

    I originally posted that Madiko was the codename of the SoC, but this is inaccurate.

    Mariko is actually the codename of the new Switch model which will use Tegra 214.

    We don't know how different this revision will be or if it's just a security upgrade. However I think it would be weird to have a codename for a model where the only difference is a security change.
  31. Starset


    What is a SoC??

    Am i dumb or something
  32. Midas


    A little bit. :P

    System on (a) Chip.

    Wonder if that's how Nintendo plans to sell another 20 million Switches next year. All the early adopters will buy the new Switches and use their old ones for homebrew.
  35. justiceiro


    They really want to avoid a wii situation, huh.
    Anyway, so far this means nothing for the end user.
  36. iamaustrian


    I think this is just an updated chip which closes all the exploit holes
  37. TC13


    Wait, I thought the Switch bootrom was patch-able?
  38. I would like to get a revised system, when will they be available and how can I differenciate an original to a new one?
  39. Thraktor


    The fact that they're using a new numbered designation for it is interesting, because I don't believe Nvidia have done that before. As far as I'm aware Switch itself uses the second revision of the T210 chip (denoted A2 on the die), and I would have assumed that something as small as fixing a security vulnerability they would have moved to A3 rather than a whole new chip number, which as far as I can tell has only been used before for substantially altered chip designs (ie new CPU/GPU arrangement). Of course it's possible to read too much into it, but it is interesting.

    One possibility is that it's a die shrink. It would be early, but it's conceivable that they've used up their original commitment of 20nm chips faster than expected, and by this point a move to 16nm would be the same price or cheaper anyway.

    Nobody knows. If it's just a security revision then they could be introduced without anyone knowing and with no easy way to tell the difference.

    The bootrom glitch won't be released for a long time, if ever. Its not a Switch issue, its a widespread issue and its not a landmine many will want to step on or even go near.

    No, you will be completely disconnected after a week or so because you'll be behind in firmware. So you'll lose access to all online functionality with the system.

    Also with the way that certificates work on the Switch, the bans that can go down are irreversible and they can sniff out of a LOT of bad behavior in a very straight forward fashion because of the layers of telemetry and how the accounts are now integrated with the system.
  41. scrapple


    hmm, interesting...
    I did hack my DS back in the day after it was pretty much not supported after the 3ds took off..
    smart by nintendo though to do this
  42. Skyfireblaze


    Didn't the 360 have many codenames without much changing for the end-user like Jasper and Falcon?
  43. ShiftaDeband


    Hm. So this could possibly be new hardware? I'm not a huge believer in the whole "Switch XL" thing, but this is an interesting development. I agree with you - strange to name a revision.

    Valid point.
  44. TwinsUltra64


    I think Nintendo will develop a Dock with its own hardware specs, If you remember Kimishima said that they won't release a revisioned switch instead they will release peripherals.
  45. I doubt they do a revision before holiday 2019 like a full one. I imagine it’s just for security and minor internal improvements like the ps4’s update in 2015 on fat model

    Tho, I would welcome a really small super pocket-able model.

    Then again we don’t even have cloud saves and can’t game share to my knowledge so I doubt it would be worth the hassle owning two switches, one solely for TV and one for the road
  46. iswasdoes


    I would like it if my launch day switch had a hardware vulnerability that meant I could soft mod it later and Nintendo could not stop me.

    Is that what this means?
  47. Thraktor


    Yep, and in both cases they came with die-shrinks to the CPU and/or GPU.

    Edit: Although not all named Xbox 360 revisions did, it seems. However in this case the change to the SoC is the only thing we know about the new model.
  48. Sanctuary


    Sure, if you are looking at it from a homebrewing perspective. I want a Switch eventually, but I've been waiting for more games (I can't justify the system for only three games, been there already with the Wii U) and hopefully some hardware improvements, which this seems like it will be doing at least somewhat.
  49. XDevil666


    Thank god, I hope version 2 is more robust.

    I will definitely be in for version 2 :)
  50. mindsale


    I was about to buy a second Switch, guess I can hold off for the revision, even if it's as small as preventing homebrew or closing a loophole.
