    A repository appeared on GitHub which apparently converts saves from the Wii U Save file format into the Switch's File format so that you can transfer your save from the Wii U version to the Switch's and viceversa.

    Link to the latest Save Manager for BotW Switch (with UI):
    https://github.com/JordanZeotni/BotW-Save-Manager


    And for additional info, here's the Save Dump and Inject programs by Rei:

    Now, how can the save be transfered to the Switch? Will something similar be done to Hyrule Warriors and other Wii U to Switch ports?

    Maybe?
    It depends on how different the ports are form each other.
    BotW was a dual release on the same day (for both Wii U and Switch version).

    But for HWDX, things are different, as that one has a lot more things into it for saving compared to the Wii U version.

    As long as we don’t have a save injector, this isn’t much of use. Too bad.

    So if we can't use the Switch save file, how do we know if this convertor even works?

    Should be possible, yes.
    Just make sure both versions of BotW have the same update version and/or DLC version as well.

    Would it possible to:
    1. dump the savegame from the switch
    2. convert it to wii u savegame format
    3. edit the wii u savegame with a wii u botw save editor
    4. convert it back to switch savegame format
    5. inject it to the switch
    6. profit?

    I don't see why not.
    Dump the Switch file and convert it to Wii U format, then try to load it up in the editor.
    Should work in theory.

    I believe the instructions are in the Save Dump link.

    I tried to dumped the savegame of botw but if got an error message:
    Code:
    ERROR: [6, 'sc.getFSPPR is not a function. (In \ 'sc.getFSPPR()\', \ 'sc.getFSPPR\' is undefined)' ]
    1. I've copied the file in to my usefulscripts folder & changed the title id
    2. run botw and go back to the home menu
    3. start pegaswitch
    4. I've run evalfile ./usefulscripts/save_dump.js
    5. error in the pegaswitch terminal appeared

    seams like the function getFSPPR is not included to pegaswitch?

    EDIT:
    used a fork from 3096 with implemented getFSPPR
    last function is not working:
    Code:
    ERROR: [ 826, '0xe02 (High byte in input u64 is zero. in module FS)' ]

    I would suggest you get in contact with Rei himself or someone from the Reswitched team perhaps, they might be able to help you out in details with those issues.

    OMG! Thanks to whoever is involved in this!! I've been requesting that to Nintendo. Too bad I'm on FW 4.1 but I'll wait for sure :)

    I believe you can just edit the Save Editor to use little endian value so you can edit Switch save directly.

    But is there a way to update BotW to 1.5.0 w/o updating the fw since 3.0.0? Afaik it's not possible.
