KH Re:CoM - Card RNG Manipulation

So during my 80HP playthrough I mentioned an exploit I found in the card drop system that can be abused. Since then I've been looking into it more and more and learning how far this exploit extends.

Basically from what I have found is that upon loading a save, the game tracks everything you do, every object you attack, every time you attack and miss, every time you roll, every time you battle, everything. So upon loading a save file and following the same path doing the same actions, you can essentially trick the game into giving duplicates of every card you needs.

I found this specific pathway while searching for any consistent way to farm 9 Ultima Weapons, a little rundown at what exactly I am doing... Upon loading the save, I go straight into a Sleeping Darkness room. Whether or not its a newly formed room or not doesn't matter, what does matter though is that you haven't killed the enemies and that you haven't destroyed more then one object in the room. There is a reason for this, in this scenario the first object you break in a room adjacent to the save room will always drop a 8 Diamond Dust but if the object you break is the third broken object in the room, it won't drop. This Diamond Dust is a sign the RNG is working as intended. After breaking the object (getting the card itself doesn't actually affect the rng but its useful to sell) touch an enemy to start a battle. When the battle starts, run away. When you run away from an enemy that is walking around the room without spawning in first, they will vanish until you enter the room. Anyway, after running the first enemy, repeat with the second one. After this, go to the door and open a Moogle Room. Run up and get a free pack of cards and it should always give the following:

(7) Pumpkinhead
(5) Fairy Harp
(9) Three Wishes
(4) Spellbinder
(9) Crabclaw

After that, buy the 500 point pack and it should always give the following:

(9) Metal Chocobo
(9) Ultima Weapon
(0) Oathkeeper
(0) Two Become One
(0) Midnight Roar

Note that over the course of this entire pathway, I only attacked once and that was to break the object that dropped the Diamond Dust and I also never rolled. Because both of these things would have changed the outcome of the packs. I also have my third deck that is named "Extra" equipped as when I had either of my 2 Attack decks equipped I got different cards.

Other scenarios I found, upon loading your save, open a calm bounty room. Before entering the chest, roll or swing your keyblade and miss only once and the chest would always give an 8 Ultima Weapon.

Another is similar, open a calm bounty and attack an object inside. Like with the first scenario the broken object will always give an 8 Diamond Dust and if you open the chest right after you will always get a 9 Fire card.

There are things I still don't know about this exploit. For one I don't know if the cards are consistent between different games because every Sora file I have comes from my 80HP save. Some worlds also seem to have the same RNG so if I were to do this in Destiny Islands I would get the exact same result but for some reason Twilight Town doesn't. Actually Twilight Town gives cards of the same type and same number but different cards. For example instead of an 8 Diamond Dust, Twilight Town gives me an 8 Metal Chocobo. Also in Agrabah I would always get an 8 Two Become One.

So far the only thing I have found that outright changes the drops are the cards you have unlocked. I farmed for 9 Oathkeepers in Destiny Islands using this exploit but now that I have all the endgame keyblades like Ultima, that specific spot doesn't work anymore and the packs are giving me things like Oblivion, DIamond Dust, One-Winged Angel and Ultima Weapon.
