Atmosphere 0.19.0 Released

Atmosphere 0.19.0

The cat and mouse game continues. Apparently there’s a 12.0.0 firmware out there on the Switch? And also I guess it’s June 15th? Here, we can explain it all right now. You know, just in case you don’t get what I mean by all of that foreplay.

Changelog for Switch 12.0.0 FW:
We fixed the issue with the save data backup feature, where in rare cases, the automatic backup of save data is interrupted if a communication error occurs during completion of the save data backup process.

Atmosphere 0.19.0 Changelog (niceties):

    Support was added for 12.0.0.
        mesosphere 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 usb30_force_enabled usb! 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.
