0.7.0

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.
