(Tested) 126x Exp After Battle
F0 ?? D2 ?? ?? 61 F7 25
F0 ?? D2 24 7e 61 f7 25
Change all 6 results; whatever you change the bolded 7E to is what your experience will be multiplied by after the fight. Don't go higher than 7E though, or the game freezes.
NOTE: After your first fight, you'll be way above the level of the monsters in that dungeon, and will therefore get 0 exp for fighting them. This is solved by going back up the steps to outside, and then restarting the dungeon. The mobs will be generated at your level, and will therefore give a ton of exp again.
(Tested) 20 Pieces of Loot After Battle
F0 ?? D2 24 ?? 61 D6 25
F0 ?? D2 24 14 61 D6 25
Again, 6 results; change the bold number to anything, but since the loot all displays on one line, it's probably best not to go above around 18, or else it'll go off the screen.
Other Hacks:
HP and MP are 4b*1. If you don't want to search for both, the HP address ends in *8. Add four to the * to get the MP address.
Your gold has two addresses to change: one is 4b*1, and the other is 4b*8+6. Both need to line up with each other to work (I set my 4b*1 to 4000000, and the other to 32000006.)
The level for each character seems to be tied to a single 4b*1 address, and two or three 4b*8+6 addresses. By changing these numbers, you will affect a) what level the mobs spawn at, b) your base stats, and c) what tier the Emporium will restock at. HOWEVER, if items have a level requirement, changing these numbers doesn't affect the level the item popups say you are, so even if you restock the emporium at tier 1000000, any item shown will have the red box around it indicating it's above your level.
