Atmosphere-NX/Atmosphere 1.9.0-prerelease

Atmosphère 1.9.0 (pre-release)

on GitHub

1.9.0 is Atmosphère's eighty-first official release.

Please be sure to update fusee when upgrading to 1.9.0. fusee-primary no longer exists, and will not work any more.

Please note: Atmosphère 1.9.0 is currently in pre-release, and issues may be found that need to be fixed before full release.

• If any bugs are reported while Atmosphère is in pre-release, they will be fixed and the build will be updated.
• 1.9.0 will transition to release after a short amount of time has passed without pressing bug reports.

With thanks to the @switchbrew team, Atmosphère 1.9.0 is bundled with hbl 2.4.4, and hbmenu 3.6.0.

The following was changed since the last release:

• Basic support was added for 20.0.0.
  • The console should boot and atmosphère should be fully functional. However, not all modules have been fully updated to reflect the latest changes.
    • There shouldn't be anything user visible resulting from this, but it will be addressed in a future atmosphère update.
    • The same action item from 18.0.0 remains, and I believe in my heart of hearts that it will be addressed eventually. Someone has told me they're working on it.
    • There aren't (to my knowledge) outstanding 19.0.0 items any more.
  • Please note: As a result of changes made to nintendo's software in 20.0.0, there is roughly 10MB less memory available for custom system modules.
    • We can only steal a maximum of 14MB from the applet pool, down from 40MB.
    • To compensate for this, ams.mitm's heap usage has been reduced by 20MB.
      • To facilitate this, a new helper module (memlet) was added, so that memory may be temporarily stolen during the romfs building process.
      • Hopefully, this results in relatively little breakage, however it is possible that user mods which replace extremely large numbers of files in The Legend of Zelda: Tears of the Kingdom may no longer function.
        • If you are affected by this, you will see "Data abort (0x101)" when trying to launch the game with mods.
        • Please reach out to sciresm on discord if this occurs to share your error report binary. However, some issues may be impossible to fix.
        • I apologize sincerely if the issue is impossible to resolve, but I have been forced unavoidably to make compromises here, and I think this is the best balance to be struck.
  • exosphère was updated to reflect the latest official secure monitor behavior.
  • mesosphère was updated to reflect the latest official kernel behavior.
  • loader was updated to reflect the latest official behavior.
  • pm was updated to reflect the latest official behavior.
  • ncm was partially updated to reflect the latest official behavior.
  • erpt was updated to reflect the latest official behavior.
• Atmosphère was updated to use GCC 15/newlib (latest devkitA64/devkitARM releases).
• A number of improvements were made to the dmnt cheat engine.
  • New instructions were added, and instructions were updated for improved/new functionality.
  • Please see the documents for details -- thanks @tomvita!
• General system stability improvements to enhance the user's experience.
