    I was going to ask the same.
    I would like playing in 4k 60fps on PC, then transfer the save to the switch to play the extra-content.
    I didn't try and search to do it yet, but I hope it's possible.

    I'm really interested in this as well. I stopped playing on PC a ways back, but I would like to finish on my switch if it's possible :P

    It's possible to transfer saves, but the PC version and Switch version does its encryption/decryption a little differently with the keys also being different.

    could this is possible? it's like 2 different games, not just a port because i see the director told that their team rebuild it completely so it can be called as a remake

    If you want to check out the differences, I've attached my encryption/decryption tool. I've also attached the source code. This tool does not fix the checksum on the save, but when I have more time, I can update it.

    Edit 1 (10-29-19):
    I've updated the tool to get the checksum. You still have to fix it yourself.

    Code:
    Switch checksum location:
    File Size - 0x0c
    
    PC checksum location:
    0x04

    How do we fix it ourselves? I'm a little lost, sorry

    Make sure to pick the correct platform for your save or it will not work since the keys are different.

    1) Decrypt the save
    2) Click "Get Checksum" and choose the decrypted save
    3) A message box will pop up with the checksum, write it down.
    4) In a hex editor replace what you were given, in the message box, and replace it at the address provided. (PC = 0x04, Switch = File size - 0xc)
    5) Encrypt the save

    it doesn't look like it's a working tool to convert saves, just an encryption/decryption tool.

    so.. just to confirm 100%
    this doesnt actually convert saves at all? I thought it found the checksum so you could convert manually

    The program will just Encrypt, Decrypt, and show the checksum of the save. You will have to manually convert the save to your desired platform. I was just only interested in the protection of the save and released a program so someone else interested in making an editor and/or converter can.
