0.8.1 is Atmosphère's eighth official release.

fusee-primary was last updated in: 0.8.1.

The following was changed since the last release:

  • A bug was fixed causing users to see Failed to enable SMMU! if fusee had previously rebooted.
    • This message will still occur sporadically if fusee is not launched from coldboot, but it can never happen twice in a row.
  • A race condition was fixed in Atmosphere bis_protect functionality that could cause NS to be able to overwrite BCT public keys.
    • This sometimes broke AutoRCM protection, the current fix has been tested on hardware and verified to work.
  • Support was added for enabling debugmode based on the exosphere section of BCT.ini:
    • Setting debugmode = 1 will cause exosphere to tell the kernel that debugmode is active.
    • Setting debugmode_user = 1 will cause exosphere to tell userland that debugmode is active.
    • These are completely independent of one another, allowing fine control of system behavior.
  • Support was added for nogc functionality; thanks to @rajkosto for the patches.
    • By default, nogc patches will automatically apply if the user is booting into 4.0.0+ with fuses from <= 3.0.2.
    • Users can override this functionality via the nogc entry in the stratosphere section of BCT.ini:
      • Setting nogc = 1 will force enable nogc patches.
      • Setting nogc = 0 will force disable nogc patches.
    • If patches are enabled but not found for the booting system, a fatal error will be thrown.
      • This should prevent running FS without nogc patches after updating to an unsupported system version.
  • An extension was added to exosphere allowing userland applications to cause the system to reboot into RCM:
    • This is done by calling smcSetConfig(id=65001, value=<nonzero>); user homebrew can use splSetConfig for this.
  • On fatal error, the user can now choose to perform a standard reboot via the power button, or a reboot into RCM via either volume button.
  • A custom message was added to fatal for when an Atmosphère API version mismatch is detected (2495-1623).
  • General system stability improvements to enhance the user's experience.

0.8.0 is Atmosphère's seventh official release.

fusee-primary was last updated in: 0.8.0.

The following was changed since the last release:

  • A custom fatal system module was added.
    • This re-implements and extends Nintendo's fatal module, with the following features:
      • Atmosphère's fatal does not create error reports.
      • Atmosphère's fatal draws a custom error screen, showing registers and a backtrace.
      • Atmosphère's fatal attempts to gather debugging info for all crashes, and not just ones that include info.
      • Atmosphère's fatal will attempt saving reports to the SD, if a crash report was not generated by creport.
  • Title flag handling was changed to prevent folder clutter.
    • Instead of living in atmosphere/titles/<tid>/%s.flag, flags are now located in atmosphere/titles/<tid>/flags/%s.flag
      • The old format will continue to be supported for some time, but is deprecated.
    • Flags can now be applied to HBL by placing them at atmosphere/flags/hbl_%s.flag.
  • Changes were made to the mitm API, greatly improving caller semantics.
    • sm now informs mitm services of a new session's process id, enabling custom handling based on title id/process id.
  • smhax is no longer enabled, because it is no longer needed and breaks significant functionality.
    • Users with updated HBL/homebrew should see no observable differences due to this change.
  • Functionality was added implementing basic protections for NAND from userland homebrew:
    • BOOT0 now has write protection for the BCT public key and keyblob regions.
      • The ns sysmodule is no longer allowed to write the BCT public keys; all other processes can.
        • This should prevent system updates from removing AutoRCM.
      • No processes should be allowed to write to the keyblob region.
    • By default, BIS partitions other than BOOT0 are now read-only, and CAL0 is neither readable nor writable.
      • Adding a bis_write flag for a title will allow it to write to BIS.
      • Adding a cal_read flag for a title will allow it to read CAL0.
    • An automatic backup is now made of CAL0 on boot.
      • fs.mitm maintains a file handle to this backup, so userland software cannot read it.
    • To facilitate this, fs.mitm now mitms all sessions for non-system modules; content overriding has been made separate from service interception.
    • Please note: these protections are basic, and sufficiently malicious homebrew can defeat them.
      • Please be careful to only run homebrew software from sources that you trust.
  • A bug involving HDCP titles crashing on newer firmwares was fixed.
  • Support was added for system version 6.2.0; our thanks to @motezazer for his invaluable help.
    • By default, new keys will automatically be derived without user input.
    • Support is also present for loading new keys from atmosphere/prod.keys or atmosphere/dev.keys
  • General system stability improvements to enhance the user's experience.

0.7.5 is Atmosphère's sixth official release.

fusee-primary was last updated in: 0.7.0.

The following was changed since the last release:

  • DRAM training was added to fusee-secondary, courtesy @hexkyz.
    • This greatly improves the speed of memory accesses during boot, resulting in a boot time that is ~200-400% faster.
  • creport has had its code region detection improved.
    • Instead of only checking one of the crashing thread's PC/LR for code region presence, creport now checks both + every address in the stacktrace. This is also now done for every thread.
      • This matches the improvement Nintendo added to official creport in 6.1.0.
    • The code region detection heuristic was further improved by checking whether an address points to .rodata or .rwdata, instead of just .text.
    • This means that a crash appears in a loaded NRO (or otherwise discontiguous) code region, creport will be able to detect all active code regions, and not just that one.
  • General system stability improvements to enhance the user's experience.

0.7.4 is Atmosphère's fifth official release.

fusee-primary was last updated in: 0.7.0.

The following was changed since the last release:

  • libstratosphere has been completely refactored/rewritten, and split into its own, separate submodule.
    • While this is mostly "under the hood" for end-users, the refactor is faster (improving both boot-time and runtime performance), more accurate (many of the internal IPC structures are now bug-for-bug compatible with Nintendo's implementations), and significantly more stable (it fixes a large number of bugs present in the old library).
    • The refactored API is significantly cleaner and easier to write system module code for, which should improve/speed up development of stratosphere.
    • Developers looking to write their own custom system modules for the Switch can now easily include libstratosphere as a submodule in their projects.
  • Loader was extended to add a new generic way to redirect content (ExternalContentSources), courtesy @misson20000:
    • A new command was added to ldr:shel, taking in a tid to redirect and returning a session handle.
    • When the requested TID is loading, Loader will query the handle as though it were an IFileSystem.
      • This allows clients to generically define their own filesystems, and override content with them in loader.
  • fs.mitm has gotten several optimizations that should improve its performance and stability:
    • RomFS redirection now only occurs when there is content to redirect, even if the title is being mitm'd elsewhere.
    • A cache is now maintained of the active data storage, if any, for all opened title IDs. This means if two processes both try to open the same archive, fs.mitm won't duplicate any of its work.
    • RomFS metadata is now cached to the SD card on build instead of being persisted in memory -- this greatly reduces memory footprint and allows fs.mitm to redirect more titles simultaneously than before.
  • A number of bugs were fixed, including:
    • A resource leak was fixed in process creation. This fixes crashes that occur when a large number (>32) games have been launched since the last reboot.
    • fs.mitm no longer errors when receiving a zero-sized buffer. This fixes crashes in some games, including The Messenger.
    • Multi-threaded server semantics should no longer cause deadlocks in certain circumstances. This fixes crashes in some games, including NES Classics.
    • PM now only gives full FS permissions to the active KIPs. This fixes a potential crash where new processes might be unable to be registered with FS.
  • The make dist target now includes the branch in the generated zip name.
  • General system stability improvements to enhance the user's experience.

0.7.3 is Atmosphère's fourth official release.

fusee-primary was last updated in: 0.7.0.

The following was changed since the last release:

  • Loader and fs.mitm now try to reload loader.ini before reading it. This allows for changing the override button combination/HBL title id at runtime.
  • Added a MitM between set:sys and qlaunch, used to override the system version string displayed in system settings.
    • System settings will now display <Actual version> (AMS <x>.<y>.<z>).
  • General system stability improvements to enhance the user's experience.

fusee-primary was last updated in: 0.7.0.

The following was changed since the last release:

  • Fixed a bug preventing consoles on 4.0.0-4.1.0 from going to sleep and waking back up.
  • Fixed a bug preventing consoles on < 4.0.0 from booting without specific KIPs on the SD card.
  • An API was added to Atmosphère's Service Manager for deferring acquisition of all handles for specific services until after early initialization is completed.
  • General system stability improvements to enhance the user's experience.

0.7.0 is Atmosphère's first official release.

It supports the following featureset:

  • Fusée, a custom bootloader.
    • Supports loading/customizing of arbitrary KIPs from the SD card.
    • Supports loading a custom kernel from the SD card ("/atmosphere/kernel.bin").
    • Supports compile-time defined kernel patches on a per-firmware basis.
    • All patches at paths like /atmosphere/kip_patches/<user-defined patch name>/<SHA256 of KIP>.ips will be applied to the relevant KIPs, allowing for easy distribution of patches supporting multiple versions.
      • Both the IPS and IPS32 formats are supported.
    • All patches at paths like /atmosphere/kernel_patches/<user-defined patch name>/<SHA256 of Kernel>.ips will be applied to the kernel, allowing for easy distribution of patches supporting multiple versions.
      • Both the IPS and IPS32 formats are supported.
    • Configurable by editing BCT.ini on the SD card.
    • Atmosphère should also be launchable by the alternative hekate bootloader, for those who prefer it.
  • Exosphère, a fully-featured custom secure monitor.
    • Exosphere is a re-implementation of Nintendo's TrustZone firmware, fully replicating all of its features.
    • In addition, it has been extended to provide information on current Atmosphere API version, for homebrew wishing to make use of it.
  • Stratosphère, a set of custom system modules. This includes:
    • A loader system module.
      • Reimplementation of Nintendo's loader, fully replicating all original functionality.
      • Configurable by editing /atmosphere/loader.ini
      • First class support for the Homebrew Loader.
        • An exefs NSP (default "/atmosphere/hbl.nsp") will be used in place of the victim title's exefs.
        • By default, HBL will replace the album applet, but any application should also be supported.
      • Extended to support arbitrary redirection of executable content to the SD card.
        • Files will be preferentially loaded from /atmosphere/titles/<titleid>/exefs/, if present.
        • Files present in the original exefs a user wants to mark as not present may be "stubbed" by creating a .stub file on the SD.
        • If present, a PFS0 at /atmosphere/titles/<titleid>/exefs.nsp will fully replace the original exefs.
        • Redirection is optionally toggleable by holding down certain buttons (by default, holding R disables redirection).
      • Full support for patching NSO content is implemented.
        • All patches at paths like /atmosphere/exefs_patches/<user-defined patch name>/<Hex Build-ID for NSO to patch>.ips will be applied, allowing for easy distribution of patches supporting multiple firmware versions and/or titles.
        • Both the IPS and IPS32 formats are supported.
      • Extended to support launching content from loose executable files on the SD card, without requiring any official installation.
        • This is done by specifying FsStorageId_None on launch.
    • A service manager system module.
      • Reimplementation of Nintendo's service manager, fully replicating all original functionality.
      • Compile-time support for reintroduction of "smhax", allowing clients to optionally skip service access verification by skipping initialization.
      • Extended to allow homebrew to acquire more handles to privileged services than Nintendo natively allows.
      • Extended to add a new API for installing Man-In-The-Middle listeners for arbitrary services.
        • API can additionally be used to safely detect whether a service has been registered in a non-blocking way with no side-effects.
        • Full API documentation to come.
    • A process manager system module.
      • Reimplementation of Nintendo's process manager, fully replicating all original functionality.
      • Extended to allow homebrew to acquire handles to arbitrary processes, and thus read/modify system memory without blocking execution.
      • Extended to allow homebrew to retrieve information about system resource limits.
      • Extended by embedding a full, extended implementation of Nintendo's boot2 system module.
        • Title launch order has been optimized in order to grant access to the SD card faster.
        • The error-collection system module is intentionally not launched, preventing many system telemetry error reports from being generated at all.
        • Users may place their own custom sysmodules on the SD card and flag them for automatic boot2 launch by creating a /atmosphere/titles/<title ID>/boot2.flag file on their SD card.
    • A custom fs.mitm system module.
      • Uses Atmosphère's MitM API in order to provide an easy means for users to modify game content.
      • Intercepts all FS commands sent by games, with special handling for commands used to mount RomFS/DLC content to enable easy creation and distribution of game/DLC mods.
        • fs.mitm will parse the base RomFS image for a game, a RomFS image located at /atmosphere/titles/<title ID>/romfs.bin, and all loose files in /atmosphere/titles/<title ID>/romfs/, and merge them together into a single RomFS image.
        • When merging, loose files are preferred to content in the SD card romfs.bin image, and files from the SD card image are preferred to those in the base image.
      • Can additionally be used to intercept commands sent by arbitrary system titles (excepting those launched before SD card is active), by creating a /atmosphere/titles/<title ID>/fsmitm.flag file on the SD card.
      • Can be forcibly disabled for any title, by creating a /atmosphere/titles/<title ID>/fsmitm_disable.flag file on the SD card.
      • Redirection is optionally toggleable by holding down certain buttons (by default, holding R disables redirection).
    • A custom crash report system module.
      • Serves as a drop-in replacement for Nintendo's own creport system module.
      • Generates detailed, human-readable reports on system crashes, saving to /atmosphere/crash_reports/<timestamp>_<title ID>.log.
      • Because reports are not sent to the erpt sysmodule, this disables all crash report related telemetry.
  • General system stability improvements to enhance the user's experience.
