[SWITCH] Released JKSV 06/01/2020

Another very useful homebrew updates one year after its last release, we are talking about JKSV from the developer JDK. Born as a small project / port to test some things and become familiar with libnx, it is now the multipurpose tool / homebrew able to perform several functions quite useful as:

  1. Dump and restore save data.
    • Includes the ability to dump and restore to / from any location on SD by pressing less and using Advanced Mode.
  2. The dump system saves the data
    • Pressing all four shoulder buttons simultaneously will re-scan and include system saves not previously listed.
    • Dumping of this data is allowed.
  3. Open and explore your storage partitions via the Extras menu
    • BIS archiving opens in a basic file browser. The partition list is on the left. Your SD is on the right.
    • Only SD copying and file properties work on BIS partitions. Writing and deleting are disabled for now.
  4. Various:
    • NAND dump
    • Ability to remove firmware updates downloaded from NAND.
    • Closing processes by  ID  . Allow to download normally unopened system archives.
    • Install   by system save ID . Normally used when the terminated process makes JKSV unable to repeat the title scan without the Switch freezing.
    • Mounting and opening RomFS of the process takes over the homebrew menu (if started as NRO)
      • Hold R while opening a game or applet with Atmosphere to load the homebrew menu. Open JKSV and press less and select  Mount RomFS process  . The app’s roms should appear in the browser along with your SD on the right.


Emergency release due to HID changes. Bug reports are appreciated. Changes compared to last year:

  • Everything is enabled. It is no longer necessary to keep a combo to enable:
    • System Save
    • BCAT
    • Save device
  • Generic icons are generated for things without icons instead of using a large ‘?’.
  • Updated for the latest version of libnx
    • The ROMFS opening code was removed until I have time to redo it.
  • Hopefully the upload in text mode is correct
