Level Data bytes:
=================================================================
Byte 1: Attribute Bonus:
------------------------
01: Add +1 to all activated bonuses
02: Add +2 to all activated bonuses
04: Add +4 to all activated bonuses
08: Activates Will
10: Activates Wisdom
20: Activates Vitality
40: Activates Agility
80: Activates Strength
------------------------

Byte 2: Hit Point Gain

Byte 3: Magic Point Gain; also, around the 50th level gained or
so (varies for each character), the ROM begins adding $20, $40,
or ($20 + $40) for each subsequent entry for this byte.  This
may have something to do with how your HP/MP/Exp needed data is
updated after you pass level 70.

Byte 4: Lower byte for Exp needed to gain a level.

Byte 5: Upper byte for Exp needed to gain a level.

=================================================================
Random Attribute Bonus Bytes:
=================================================================
------------------------
01: Add +1 to all activated bonuses
02: Add +2 to all activated bonuses
04: Add +4 to all activated bonuses

(Putting 01, 02, and 04 together seems to give a -1 instead;
the game never uses 02 and 04 together.  Putting 01 and 02
together simply gives +3, as expected)

08: Activates Will
10: Activates Wisdom
20: Activates Vitality
40: Activates Agility
80: Activates Strength
------------------------


changed $7B728's value from E1 (raise Strength, Agility, and Vitality 1 point) to E6 (previously unknown) 
for Dark Knight Cecil's 11th level, and when I ran a new game on the ROM/had DKC level up, it raised the 
indicated values by 6 points instead of the previous 1.  So adding 02 and 04 together gives +6. 

Using E5 instead gives a +5 modification.  It seems only having 01, 02, and 04 all at the same time produces the -1.
