Exactly!
Now, what's about the Level 4 weapons? Didn't know they existed. Is there any data how to change the save file to get one? In the pastebin ScarletKohaku
gave me, there's nothing about them. Moreover, there seem to be some weapons missing like Link's Spinner. Aren't they available in the 3DS version?
If you look back in the topic, there is an image of a Level 4 Great Fairy weapon along with the offset for it. I'll look up the offsets for the rest of the Level 4 weapons and the Spinner once I get the motivation to constantly switch my save between my PC and my N3DS to test. Or I could just look up my Level 4 weapons and my spinner and post the IDs I find and then someone else can confirm them.
EDIT: Turns out I got the wrong weapon, I used a different Great Sky Fairy + and its ID is 3F. I'm compiling a list of Level 4 weapon IDs right now.
EDIT 2: What I've found so far is that everything between the Master Sword (3C) and Cia's Level 1 weapon (51) is a Level 4 weapon. However, there may be more IDs after King Daphnes' Level 3 weapon. Unfortunately, since my home is Spring Break Central to a trio of rowdy grandkids, I don't have the focus to continue, especially since it seems a lot of my Level 4 (and maybe 3) weapons are of the default type (0 stars, 7 empty slots) so I could give the wrong offset accidentally.
EDIT 3: Here's a pastebin. If the weapon has the actual name, that means I actually looked up one I own in hex. If not, then it's just a guess based on the Level 1-3 weapon ID orders.
