Titles other than 32-bit are added to exceptions.txt which is treated as Black list, you can find it in root of repo. SaltyNX reads it from SaltySD folder. X at the beginning of titleid means that this game will not load any patches and plugins.

32-bit games are ignored by default for patches and plugins.

Compatibility

Tests were done on FW 7.0.1-16.0.0 with Atmosphere up to 1.5.0.

Known issues

  • Instability with some homebrews and sysmodules (like emuiibo),
  • You need to have at least Hekate 5.0.2 if you don't want issues related to Hekate,
  • 32 bit games are unsupported,
  • Cheats using directly heap addresses may not work properly while using plugins,

Changelog

0.5.2

  • Fix RTLD detection for getBID() in older games like LA Noire.

0.5.1

  • Add function SaltySD_GetBID() to use with plugins to retrieve buildID of running game.
  • Fix bug that was causing SharedMemory to not clean up upon detection of game that is 32-bit or in exceptions.txt (fixes bug in homebrew reading SharedMemory, f.e. Status Monitor Overlay, FPSLocker and ReverseNX-RT). Thanks to ~cucholix for finding this bug and testing fix.

0.5.0

  • Add SharedMemory 4096B block to use with plugins.
  • SaltyNX is reserving 4096 byte block to use with any app. Default purpose is to allow exchanging data in real time between homebrew and plugins without using dmnt:cht/svcDebug

0.4.0a-hotfix

  • Fixed sm compability issues with Atmosphere 0.19.0+.
  • Thanks to SciresM for providing this fix - 2e0bd1d!

0.4.0a

  • Resolves issue with nonconsistent heap reserving.
  • FIFA 18-21 and Darksiders 2 are now working properly.
  • EDIT: It doesn't work correctly with M.16.2 (0.16.2 EXPERIMENTAL). Works on standard 0.16.2.

0.3.2a

  • Fix loading plugins from titleid folders ef8ff67.
    • It should now fix bug introduced from 0.3.0a with crashing plugins in Smash Bros and other games while using title specific plugins.
  • Include another exception - abort loading plugins if: titleid & 0x1F00 != 0

0.3.1a

  • Fixed rare case of crashing game when trying to load hbloader in title replacement mode by disabling bootstrap in this case.
  • 2MB fix reverted, as this was crashing Zelda BoTW.

0.3.0a

  • Add support for patches (more in readme).
    • Thanks to this it's possible to omit crashes with code injection if it doesn't need heap to work.

0.2.1a

  • Reduced RAM usage by 320kB.

0.2a

  • Ditched Spawner.
  • Rewrited Proc to be independent and now it's booted directly from CFW as sysmodule.
    • Thanks to this I could lower memory usage by 60 kB.
  • Added option to disable log writing (writing is enabled by default).
  • Added toolbox.json to bring correct support for sysmodules managers.
  • Because of ditching Spawner, KIP is not possible to use anymore. That's why we have now only one package using exefs.
  • saltysd_proc.elf from SaltySD folder is not used anymore, you can delete it.

0.2

  • Update solving compability issues with FW 10.0.0 for people using NSP.zip.
  • Issue is not existing for KIP, so you don't need to update anything if you are using it (appstore is using NSP.zip).
  • Delete folder 0100000000534C56 from contents/titles before updating.

0.1a 0.1.2a

  • Implement hack to resolve issues with cheats in Atmosphere.

0.1.1a

  • Now aborting bootstrapping if titleid is higher than 0x01FFFFFFFFFFE000.

0.1a
