Hey guys with the help of feudalnate, Jappi88 and Ryo Hazuki I was able to find out the checksum for this game.
How to use:
EDITOR:Code:1. Extract your save from your USB and make a BACKUP 2. Open your save into Horizon and Extract the "saves.cfg" file from the save 3. Open your "saves.cfg" file into the Editor 4. Mod what you want and Save (DO NOT ADD/REMOVE VALUES, ONLY REPLACE) 5. Replace the "save.cfg" file back into your Save 6. Rehash/Resign your save and put your save back on your USB 7. PLAY!
NOTE: DON'T FORGET TO PRESS THE THANKS BUTTON IF YOU USE THIS!!!!
NOTE 2: DO NOT ADD/REMOVE VALUES, ONLY REPLACE, YOU WILL CORRUPT YOUR SAVE IF YOU DO!!!!
Thanks to feudalnate for PackageIO and for supplying the Checksum Fix code
Thanks to Jappi88 and Ryo Hazuki for helping me with finding out how the checksums were calculated
