Okay I made this tool since the only way to mod this game was to pay the creator of SAIO to use his tool. anyway I hope this helps. if you want a save editor to be made just let me know and send me saves with stats.
Code:How to Use: 1. Go to tools and de-compress your save 2. mod your save in hex workshop or hxd etc. 3. go to tools and hit compress 4. rehash and resign.
