This is how you'd go about editing the data..
1) Extract the save (STFS) from device (USB/HDD)
2) Extract save data (MC02) out of the save (STFS)
3) Extract the actual save data out of the save data (MC02) with MC02 Package Tool
4) Open actual save data in a hex editor
5) Do edits and save
6) Overwrite actual save data (newly edited) in save data (MC02)
7) File > Save in MC02 Package Tool, click yes when prompted to hash
8) Overwrite save data (MC02) in save (STFS)
9) Hash/sign save (STFS)
10) Overwrite save (STFS) on device (USB/HDD)
