1. Backup your saves!!!! Your saves are in "C:/users/{user}/AppData/Roaming/Rune Factory 4 Special/"
2. Copy the save you want to modify to the directory where the downloaded QuickBMS executable is
3. Edit your save using RF4 Save Editor - v0.0.8 RF4S V3.exe
WARNING: Do NOT edit Raven's FP, including the "Max FP for everyone" option! It will mess up your save file!
4. When you're done, save.
5. Finally, the save file needs a small adjustment. Simply execute the following in the command line:

./quickbms.exe rf4save.txt rf4_s01.sav

Adjust save file name if needed.
6. Copy the modified save file to its original location.

Thank you very much for saving my save！！！！By the way，the command "./quickbms.exe rf4save.txt rf4_s01.sav" requires declaring the path in window os, otherwise print " No such file or directory".
