12zv1i9.png


Atmosphère, Team ReSwitched's custom firmware for the Nintendo Switch has reached a milestone 0.7.0 release. Tagged as a pre-release, it's the first public official release of Atmosphère, which has been teased for months by SciresM. The wait is now over, and you can enjoy an early version of it by heading over to GitHub to download the pack. Full features are as described by the team below.

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 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 on 2.0.0+
        • Redirection will be optionally toggleable by holding down certain buttons.
      • 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 firmare 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.

Atmosphere need to release because SXOS is gaining more fan by days. Even detractors of SXOS paid for SXOS due to USB XCI loading.

"General system stability improvements to enhance the user's experience." Nice touch.
Atmosphere agreed with Nintendo that stability is Paramount.

This is great to see the first official release... Many great things to come.
Is it possible that this is just a ploy to steal thunder away from SXOS USB XCI loading win?

You do realise that Atmosphere doesn't do the things that people buy TX for?

Wait you're the guy that thinks auto RCM is evil

So the way this reads, I bet they are reusing Nintendo’s code with edits made here and there. Can’t wait for them to get sued to hell.
I looked up the meaning of reimplementation but I guess I have a different dictionary, as it implies the contrary.

So much tension here. I just preordered the Smash Switch bundle and I don't know if I'm going to hack it like all my other consoles. Maybe hold off until the ultimate end user experience is complete.

It's a similar idea to WINE. They don't re-use any Nintendo code - instead, they determine how it works generally (what outputs are expected for what inputs) and re-write it from scratch conforming to those specifications.

Well, more CFW is better in the first year, great. The problem is after when they need to make a standard to develop homebrew to work in all cfw and no sabotage each other to have one utility and only one.
