Section 1: D&D Character Memory Blocks and Intro
____________________________
Disclaimer:
I'm not in any way responsible for what you do to your saved games
or your games in general. Don't flame or spam me for any damage you've
done to yourself :p

Onwards...

In D&D:EoB, characters are stored in memory blocks which I call
character memory blocks. Each character memory block uses approximately
304 bytes worth of data. (I hope I counted right) Every byte controls
every item, skill, spell, level, exp, and feats of that character.
Character memory blocks correspond to the order in which the
characters are listed at the Recruiter. Even the characters that you run
across on your adventures that you can also recruit can be found here and
listed along with the pre-set or rolled characters.

I assume there's a limit to how many characters you can roll or
create, I haven't went THAT far, so don't ask me :p
If anyone took a look at the Zoids GBA Hacking Guide in the same
GameFaqs, you'll notice resemblance between this and that one. Yes, I
structured it similarly because the memory blocks themselves are rather
similar.

One thing to note: Even if you remove a character from your party, that
character still remains existant and counts in the number of character
memory blocks. (a difference in these memory blocks compared to Zoids
memory blocks, thank god)

Section 2: Byte by Byte
____________________________
Here's the breakdown of the main bytes for a character memory block.
Byte numbering is not random by any means, and the value in parenthesis
is the address for the first rolled character you've created.
Note that since I don't know whether or not there exists a byte before
this section that affects the character, the first byte I've listed might
not be the actual first byte... But for all intents and purposes, they are
in here :p

Byte 296-302 (03002770) Spell Slots??? - #161-7
Byte 303 (03002777) Spell Slots??? - #168

Race Code - The code that denotes what race the character is. For further
information, exact values and their meanings, see Section 4.

Alignment Code - The code that denotes what alignment the character is.
For further information, exact values, and their
meanings, see Section 5.

Gender - 0 for male, 1 for female

Feats - Just three bytes for all the combinations of Feats your character
could have... For further information, exact values, and their
meanings, see Section 6.

Item Code - The code that the game uses to distinguish the items your
character wears or has. See Section 7 for more info.

Spellbook Code - Eleven bytes for all the combinations of spells (both
Cleric and Wizard) your character could have... For
further information, exact values, and their meanings,
see Section 8.

Arcane Spells Section - It seems that the game stores all the spells first
in this section (both Cleric and Wizard spells),
the value in this byte equals to the number of the
Cleric and Wizard spells you have readied. (?)

Divine Spells Section - After the spells are stored in the Arcane Spells
section, then the game shifts cleric spells over
to this section. The value in this section equals
to the number of spells shifted over from the
Arcane Spells section, any remaining spells left
in there are left alone.

Spell Slots - I will generalize them as Arcane spells because of the fact
that all spells would appear in the Arcane Spells Section if
the Divine's value was 0. The values in these spell slots
correspond to the name of the spell...

WARNING: It seems that you CAN possibly have 160+ spells under your belt,
up until 255, but the main problem is that this will
override/overflow into the next character's memory block.
To avoid doing so, limit yourself to within 160 spells for safety
measures.

Section 3: Character Block Address Table
____________________________
Remember, this is the beginning of each character memory block. Apply
all hexadecimal rules to get to the address of your choice. I haven't
tested most of the blocks, so use with caution, and always have a backup
save file before attempting.

I've only listed the first 20 memory blocks and their first addresses,
if you rolled/encounted more characters and the list is longer, just
follow the pattern and add as necessary.

#1 - 3002188
#2 - 30022b8
#3 - 30023e8
#4 - 3002518
#5 - 3002648
#6 - 3002778
#7 - 30028a8
#8 - 30029d8
#9 - 3002b08
#10 - 3002c38
#11 - 3002d68
#12 - 3002e98
#13 - 3002fc8
#14 - 30030f8
#15 - 3003228
#16 - 3003358
#17 - 3003488
#18 - 30035b8
#19 - 30036e8
#20 - 3003818

____________________________
Section 4: Race Code Table
____________________________

Self-explanatory. The values 0 through 6 are the ordinary values
used in the game, the values beyond that seems to be available, experiment
with them and see what you find out :)

Race:
0 - human
1 - shield dwarf
2 - moon elf
3 - rock gnome
4 - half-elf
5 - Lf. Halfling
6 - Half-Orc
7 - Cleric....(???)
8 - Fighter
9 - Rogue
10 - Wizard
11 - Lawful Good....(??? etc.)

____________________________
Section 5: Alignment Code Table
____________________________

Similar in nature to the Race Codes, 0 through 8 are the values used
ordinarily by the game.

Alignment:
0 - Lawful Good
1 - Lawful Neutral
2 - Lawful Evil
3 - Neutral Good
4 - Neutral
5 - Neutral Evil
6 - Chaotic Good
7 - Chaotic Neutral
8 - Chaotic Evil
9 - Strength....(???)
10 - Dexterity (etc.)

____________________________
Section 6: Feats
____________________________

Now, this is the second longest section in this series. Each of the
three bytes (#60, 61, 62) that enable your character to use Feats work in
a very tedious way. You'll see why when you look at the pattern.
I will list only a part of the pattern in the first byte, and for
the other two bytes, I will only list the first and the last values.

Byte 60
---------
0 - none
1 - alertness
2 - armor prof. (heavy)

Section 7: Item Code Table
____________________________
Just as exactly as it appears in your equipment. Each one of the
known ones can be placed on any equipped slot, whether or not they'll work
on inventory or potion slots is a whole different matter and I won't go
that far yet.
Also, they are not tested to see if they can actually be
usable/re-equippable/removable/etc, they are only tested to see whether
they'll cause automatic crashes to your game. Use at discretion.

All spots marked with (empty) literally have no item names, I haven't
tested to see if they actually have affect on the character, any spots
marked with anything other than (empty) contains the item name as
indicated.

#156 I believe is the fake Elixer of Life, just as a warning. Test it
yourself with an experimental character.

____________________________
Section 8: Spell Code Table
____________________________
The pattern and format is the same as the feats, so I'll make it
simple enough and list only the first and last values (listing all 255
combinations on each of the 11 bytes is tedious and a waste of time and
space...).

Note: The repeat of "Hand of Pronto" in byte 119, 121, 123, and 125 is
not a mistake, it seriously DOES appear multiple times...

The spelling error of "Neutralize Poision" in byte 124 is also not my
mistake, I simply copied what exactly appeared on the screen.

Byte 116
---------
0 - None
255 - Cure Minor Wounds + Inflict Minor Wounds + Feather Fall + Resistance
+ Virtue + Ray of Frost + Acid Splash + Electric Jolt

Byte 117
---------
0 - None
255 - Bane + Bless + Cause Fear + Cure Light Wounds + Doom +
Inflict Light Wounds + Spider Climb + Protection from Chaos

Byte 118
---------
0 - None
255 - Protection from Law + Protection from Good + Protection from Evil +
Remove Fear + Shield of Faith + Cone of Cold + Mage Armor +
Detect Secret Door

Byte 119
---------
0 - None
255 - True Strike + Charm Person + Sleep + Magic Missile + Ray of
Enfeeblement + Hand of Pronto + Aid + Bull's Strength

Most of the credit goes to the creators of this wonderful and fun RPG game :)
And for GameFaqs and everyone in the boards.

Also, as I've mentioned in Section 1, the FAQ structure is not mine.
That credit goes to Soren Kanzaki for his very in-depth FAQ.

Constructive criticism welcome at [email protected] .
