I was just poking around trying to figure out how 7th saga calculates experience points.

Here's a good line:

$C2/8044 A9 34 02    LDA #$0234

I figured out that the game multiplies all experience values from the table by 2.2.  This line loads in the multiplier number of 2.203125  (0234 is an 8.8 fixed point number).  So a monster with 0C (12) as its EXP value actually gives you 1A (26) EXP.

And that is what you hack if you want to have the monsters give you triple EXP.

We have the rom patch:
C28046:06
Or Game Genie Code:
D160-7F66

This makes the monsters give you 6.2x as much exp instead of 2.2x exp.
