    Hey guys,
    as you might know, some games have a checksum built into the save files, so you can't edit them without them being corrupted.
    To remedy this I made a small tool, that calculates valid checksums for Rune Factory 4 saves.

    1. Edit saves, change money or anything.
    2. Put my tool into the save file directory or the parent directory, if the saves are in a 00000d28 subdirectory.
    3. Start the tool.
    4. Et voila, you now have totally valid saves.

    Feedback is welcome. I'll include the C++ source file as well.

    Have fun,
    SeiKur0


    PS: Can someone make me a save editor for this game now? ;)

    edit:
    Updated the program, it didn't apply the hash to the third slot savefile.

    Would be interesting to know, you could test it. And if it doesn't work you could send me the some valid japanese save files, so I can make it work with them.

    All I want from this is to not have to wait so damn long for Arc 3 and the marriage events. Anyway to force them?

    Maybe. I would imagine, there is an address for the currently active event and for the event progress in the game. If you could get some saves with different events active and maybe different stages of these events, I might be able to find the address. I'm currently working on mapping the save and then releasing a save editor.
