  • 0100000000000824(Mariko Config), 0100000000000825, 0100000000000826 were added.
    • 0100000000000824 provides configuration for the new "T214" SoC.
    • 0100000000000825 contains an empty "/blacklist.dat" file.
    • 0100000000000826 contains a 0x40-byte "/version" file, this is all-zero except for '0' at offset 0x20.

The built codebins now have padding in .text after every function for 0x10-byte alignment.

The SDK included with titles (main-codebin) for NV changed/updated NVIDIA hw strings:

Everything under RomFS was updated.

A new folder "a" was added, in addition to the existing "nx" folder, containing a separate "bct" and "package1". Both of these seem encrypted/meant for the new "Mariko" hardware that support was added for.

The following firm-sysmodules was added to both safemode-firm, which were originally in separate sysmodule-titles: Bus, PCV, and psc.

All firm-sysmodules were updated (might be due to updated (?) rtld).

Secure Monitor

The Memory layout was changed significantly:

  • .text, .rodata, and .data are now separate sections, instead of being mapped RWX.
  • Physical layout in TZRAM changed significantly, with pk2ldr being in low TZRAM instead of high TZRAM.

In addition, there were changes to the SMC interface:

  • smcLoadSecureExpModKey/smcLoadRsaOaepKey/smcDecryptRsaPrivateKey no longer exist.
  • smcLoadRsaOaepKey was replaced with smcEncryptRsaPrivateKeyForImport.
  • smcDecryptRsaPrivateKey was replaced with smcDecryptOrImportRsaPrivateKey.
    • All keys which were previously imported with specific keys now first call smcEncryptRsaPrivateKeyForImport with the appopriate enum member to get a sealed copy of the RSA key, then smcDecryptOrImportRsaPrivateKey to import/unseal the key when needed.
  • smcGetConfig was extended with two new config items:
  • -GetConfig(16) now does the following, which seems to check whether the Switch is running on a Tegra 210:
   return (FUSE_RESERVED_ODM4 & 0x800) &&  FUSE_RESERVED_ODM0 == 0x8E61ECAE &&  FUSE_RESERVED_ODM1  == 0xF2BA3BB2 ?  (FUSE_RESERVED_ODM2 & 0x1F) : 0
  • Getconfig(17) now checks whether package2 is plaintext or encrypted.

<fill in the rest later>


  • Kernel Address Space Layout Randomization was added.
    • Instead of using a hardcoded address for per-CPU region, they now use x18 to point to the per-CPU region.
  • 5 new syscalls.
    • SVCs 0x48/0x49 are accessible by AM-sysmodule.
  • NPDM irq_id's are no longer checked to be < 0x100, instead max-value is loaded from per-cpu state.
  • The order slabheaps are laid out in memory is now randomized.

Internet Browser

OSS/WebKit was updated.

In the NPDM, besides the RSA region the only changes were the kernel-release-version descriptor + {new ACID flag is set}.

In the "shareddata:/" title, the NROs are now compressed: "{name}.nro.lz4" instead of "{name}.nro".


RomFS changes:

  • "/common/shader/VarietyOceanShader_Nx.arc.szs" updated
  • "/lyt/common.szs" updated
  • "/lyt/DummyGameA.szs" and "/lyt/DummyGame.szs" were removed.
  • "/lyt/Entrance.szs" updated
  • "/lyt/Eula.szs" added
  • "/lyt/Flaunch.szs" updated
  • "/lyt/Gift.szs" updated
  • "/lyt/Interrupt.szs" updated
  • "/lyt/Migration.szs" updated
  • "/lyt/Notification.szs" updated
  • "/lyt/Option.szs"
  • "/lyt/ResidentMenu.szs"
  • "/lyt/Set.szs"
  • "/message/" Everything under here was updated.
  • "/message/Ocean.msbp.szs" added
  • "/sound/qlaunch_action.bksnd" and "/sound/qlaunch.bfsar" were updated.
  • "/texture" Directory was added, which contains images for Nintendo Switch Parental Controls:
    • "IcoPctl.bntx"
    • "LogoMoon{region/language-text}.bntx", for every region/language.


New flags bit2/bit3 were added to the flags at ACID+0xC.


Keyblob 5 is now used, instead of 4. New NCA keydata is now used as well.
