Notes

To use this code, start a game and save anywhere you like. Now reload that save, and you will notice that Leech Hunter Mode is now unlocked. Go into it and simply walk out the door. You will now have unlocked all rewards from Leech Hunter Mode. Save and reload your game again without the code active and you're done. Congrats, you now have everything, by doing nothing!

This code modifies the item you pickup and drop on the ground. Hold the Z button down when picking up or dropping an item to drop or recieve that item instead.
