Atmosphère 0.19.0

on GitHub

0.19.0 is Atmosphère's forty-sixth official release.

fusee-primary was last updated in: 0.17.0.

With thanks to the @switchbrew team, Atmosphère 0.19.0 is bundled with hbl 2.4.1, and hbmenu 3.4.0.

Note: The NCM build in the 0.19.0 zip was updated on 2021/04/11 at 5:45 AM PST to fix a random crash when deleting games. The updated zip has a build hash of "-c67c29eb".

The following was changed since the last release:

• Support was added for 12.0.0.
  • mesosphère was updated to reflect the latest official kernel behavior.
  • sm, boot2, pgl were updated to reflect the latest official behaviors.
    • Please Note: 12.0.0 added a new protocol for IPC ("tipc"), which has been freshly reimplemented in its entirety.
      • It is possible there may be as of yet unfound issues; if there are, please send the appropriate crash reports to SciresM (SciresM#0524 on discord).
      • Homebrew which uses atmosphere extensions (including the mitm API) will need to be re-compiled in order to function on 0.19.0.
        • I apologize for this, but it's unavoidable for technical reasons. If you're affected by this and mad about it, please contact SciresM to complain.
  • erpt was partially updated to reflect the latest official behaviors.
    • New features were added to erpt to track the activity of running applets, and to detect when a forced shutdown occurs.
    • These behaviors have been temporarily stubbed, as they are not necessary for 12.0.0 to run (and their outputs won't be saved anywhere).
    • A future atmosphère update will implement these behaviors, in the interest of reflecting official logic as faithfully as we can.
• Atmosphère no longer uses the /contents/ folder for its own programs.
  • Atmosphère's system modules are now bundled together in the single file "stratosphere.romfs".
    • For those working on developing for atmosphère, executables inside the /contents/ directory will be preferred to those in "stratosphere.romfs".
  • Please Note: In order to facilitate this change (and the desired behavior), the first time you boot after extracting a release zip, atmosphère system modules inside /contents/ will be deleted.
    • This will have no impact on user programs (it only removes programs with specific program ids).
• Improvements were made to mesosphere, including:
  • An extension InfoType was added for getting the current process handle, without having to spawn a thread and do IPC with oneself.
  • An issue was fixed in SvcSetDebugThreadContext.
  • An issue was fixed when doing IPC with user buffers.
• Support was fixed for toggling the custom setting usb!usb30_force_enabled on 9.0.0+.
  • This was broken by Nintendo's introducing a dependency that made USB a requirement to launch before custom settings are parsed.
  • Since the fix, you can now toggle the setting (as you could prior to atmosphère 0.9.4), and it will work as expected.
  • Please Note: Enabling USB 3.0 often severely impacts wireless communications.
    • Because of this, the setting will default to off. If you experience issues with it enabled, consider disabling it.
• A warning was added to daybreak when resetting the console to factory settings.
• Substantial work was completed towards atmosphere's upcoming implementation of the host target connection protocol.
  • Once completed, users will be able to interact with a Switch running atmosphère via a PC application ("Starlink") currently under development.
    • Planned eventual features for connected consoles include a gdbstub, interacting with memory (for cheat development), streaming gameplay audio and video, and accessing the Switch's SD card filesystem.
    • Switch homebrew will also have access to a (configurable and sandboxed) filesystem on the host PC, while connected.
  • Towards this end, the following was accomplished:
    • The "htc" system module was reimplemented completely.
    • The system module which provides remote access to the SD card was reimplemented completely.
  • This is currently the active focus of atmosphère's development.
  • Please Note: Support is not yet completed, and users are disadvised from interacting with the related settings for the time being, unless they particularly know what they're doing.
• A number of minor issues were fixed, including:
  • A bug was fixed in dmnt that could cause a fatal when launching certain games with cheats active.
  • An issue was fixed that could cause an abort in sm when using a large number of custom system modules.
  • An issue was fixed that prevented launching gamecards on 1.0.0.
  • Minor issues were fixed in the cheat virtual machine's behavior.
• Several issues were fixed, and usability and stability were improved.
