Hey guys, I threw together this Editor pretty fast, it's not perfect but that's because I know Jappi88 is going to be making a better one :P
How to Use:
SPLASH:Code:1. Extract your Save save off your USB using Horizon 2. Open Save into Horizon 3. Click the "Contents" Tab 4. Extract the "savegame.txt" file 5. Open the "savegame.txt" file into the Editor 6. Mod the savegame and press Save 7. Replace the "savegame.txt" file back into your Save 8. Rehash/Resign 9. Put the Save back onto your USB 10. PLAY!!!
NOTE: YOU MIGHT ONLY BE ABLE TO MOD YOUR OREN NEAR THE BEGINNING OF THE GAME
