While playing this game, I stumbled upon a glitch. So I TAS'd all the way to that point, but it froze the game. =/
Would this glitch lead to something useful?

Edit:
To make finding discoveries easier:
Every map from the game with labels on items:
https://drive.google.com/folderview?id=0B-2O13fpsnI4aWNBZzlxYUtOa1E&usp=sharing
Spreadsheets for cards, combinations, locations, etc
https://docs.google.com/spreadsheets/d/1JqcTqljPon_bStQe32S7LKRxshu37ZybB74w_6WKxuE/edit?usp=sharing
Edit2: For testing purposes, a script that automatically unlocks all cards and combos
Download Cards.luaLanguage: lua
--Get all cards
for i = 0x650A, 0x656E, 1 do
memory.writebyte(i,9,"WRAM")
end
--Get all combos
for i = 0x6570, 0x6575, 1 do
memory.writebyte(i,0xFF,"WRAM")
end
memory.writebyte(0x6576,7,"WRAM")
Just run it once, and it will give all cards x 9 + combinations

Monsters in battle are offset 0xA2 of each other
0xC4B8,0xC55A,0xC5FC is HP
0xC46A,0xC50C,0xC5AE is X
0xC46D,0xC50F,0xC5B1 is Y
0xC48A,0xC52C,0xC5CE is Sprite (not ID!)
This is needed since they technically don't have a "fixed" location; monster 1 can appear in top middle or bottom.

Edit: Enemy HP and stats are mirrored multiple times on WRAM and System Bus. It appears the ones in 0x541E, 0x5437, 0x5450 in WRAM are the ones that are responsible for HP (ie, editing them has an effect).
