Atmosphère 0.10.2

0.10.2 is Atmosphère’s twenty-fifth official release.

fusee-primary was last updated in: 0.10.2.

With thanks to the @switchbrew team, Atmosphère 0.10.2 is bundled with hbl 2.3, and hbmenu 3.2.0.

The following was changed since the last release:

• hbl configuration was made more flexible.
  • Up to eight specific program ids can now be specified to have their own override keys.
  • This allows designating both the album applet and a specific game as hbl by default as desired.
  • Configuration targeting a specific program is now mutually exclusive with override-any-app for that program.
    • This fixes unintuitive behavior when override key differed for an application specific program.
• Loader’s external content fileystem support was fixed (thanks @misson20000!).
• KernelLdr was reimplemented.
  • This is the first step towards developing mesosphere, Atmosphere’s planned reimplementation of the Switch’s Kernel.
  • The typical user won’t notice anything different, as there are no extensions, but a lot of groundwork was laid for future development.
• Improvements were made to the way Atmosphere’s buildsystem detects source code files.
  • This significantly reduces compilation time (saving >30 seconds) on the machine that builds official releases.
• Certain device code was cleaned up and made more correct in fusee/sept/exosphere (thanks @hexkyz!).
• A number of changes were made to the way fs.mitm builds images when providing a layeredfs romfs.
  • Some games (Resident Evil 6, Football Manager 2020 Touch, possibly others) have enormous numbers of files.
  • Attempting to create a layeredfs mod for these games actually caused fs.mitm to run out of memory, causing a fatal error.
  • The code that creates these images was changed to be significantly more memory efficient.
  • However, these changes also cause a significant slowdown in the romfs building code (~2-5x).
  • This introduced a noticeable stutter when launching a game, because the UI thread would block on the romfs creation.
  • To solve this, fs.mitm now lazily initializes the image in a background thread.
  • This fixes stutter issues, however some games may be slightly slower (~1-2s in the worst cases) to transition from the « loading » GIF to gameplay now.
    • Please note: the slowdown is not noticeable in the common case where games don’t have tons of files (typical is ~0.1-0.2 seconds).
    • Once the image has been built, there is no further speed penalty at runtime — only when the game is launched.
• A number of other bugs were fixed, including:
  • Several minor logic inversions that could have caused fatal errors when modding games.
  • Atmosphere’s new-ipc code did not handle « automatic » recvlist buffers correctly, so some non-libnx homebrew could crash.
  • fs.mitm now correctly mitms sdb, which makes redirection of certain system data archives work again.
    • In 0.10.0/0.10.1, changing the system font/language did not work correctly due to this.
  • A bug was fixed in process cleanup that caused the system to hang on < 5.0.0.
• The temporary hid-mitm added in Atmosphere 0.9.0 was disabled by default.
  • Please ensure your homebrew is updated.
  • For now, users may re-enable this mitm by use of a custom setting (atmosphere!enable_deprecated_hid_mitm) to ease the transition process some.
  • Please note: support for this setting may be removed to save memory in a future atmosphere release.
• General system stability improvements to enhance the user’s experience.
