Well
@iSharingan basically figured out how the arena stuff works, now I just need a list of quests that matches each section
I gave you the list via PM when I first found the offsets
The order is Malfestio, Khezu, Najarala, Rathalos, Kecha Wacha, Plesioth, Brachydos, Great Maccao, Gypceros, Bird Wyverns with the first 7 being hunter quests and the last 3 being Prowler quests.
Each of the quests has 5 entries (all one after the other) and all entries are exactly 4 bytes long.
the first byte in the first quest is at 0xa0206 relative to the first byte of the player's name in the save slot (or 0x1108 from the start of the player's guild card)
As far as editing these, the rank is stored separate from the time, so you'll need to edit both if editing for all S rank. Also, while editing S rank onto the guild card works for the awards, you still need to complete at least one quest legitimately at S Rank to unlock all the gift items from the Arena Instructor.
@iSharingan Ill take that 98% save I can do the rest myself
before I release a version of my save, I'm going to strip it down so as to effectively force people to import their own save's game-specific data. Its going to take some doing to strip everything down, so I'd rather not do that twice. Patience my friend, patience.
