    Hello guys,

    Just recently tried to edit the save : rf4a.sav
    so here is some of the addresses

    0000004A-4D = Money
    0000003B-3C = Wood
    0000003F-40 = stone


    well, the only problem is the checksum, any idea how to calculate it? :/

    I think if you use save data filer, you can export a decrypted save file, edit it, and then import it back and it fixes the checksum for you.
    Unless its a card2 save, in which case, nothing can be done currently.

    Really? I already tried that serveral times, and it corrupted. Does it because of the 6.x encryption?
    Oh yeah, its card1 game.

    No SavaDataFiler doesn't fix the checksum, you have to do this yourself. Send me two or three save files with little to no difference (save in the game, export the save, load the game again, save right away, export the save again) and I can try to help you

    I just found out more about the save encryption. As of now I'm able to disable the save checksum check with a patched rom. Maybe I can find out the details of the hash generation, then I could make a checksum calculator tool :)
