==Charm Data==

Geiger

<pre>01E9D5 - Beginning of charm processing
0C235C - Charm chance</pre>

Also of note, normally, Ayla has a fixed 27.7% chance to charm an item.  With
the Charm Top, this chance is tripled to just over 82.4%.

All determination of whether you get the item or not is done well before Ayla
even fluffs her hair.

Have not checked into Twin Charm yet.

Interesting stuff.  From watching what's getting stored to 7EAEE7 and 7E0016,
Twin Charm gets the byte at 0C2464 ($50).  In other words, 31.4%  Hmm, is that
correct?  That isn't much of an upgrade.

Breakpoint C1D5EF is worth noting.  When you perform an attack or tech, it
loads 12 bytes of data (starting at 0C213F), the second of which is the %
chance?

Trying to break down the Charm code further:

<pre>C1E9D5   C1E9DA   CODE   N   Start of Charm processing
C1E9DB   C1E9DE   CODE   N   Check if Charm Top is equipped
C1E9DF   C1E9DF   DATA   N   Charm Top item index ($A5)
C1E9E0   C1E9E1   CODE   N   Check if Charm Top is equipped
C1E9E2   C1E9E9   CODE   N   Charm Top equipped, increases Charm chance to
82.4%</pre>

<pre>C1EA27   C1EA3F   CODE   N   Charm - stolen bit $80 and gets item reward index
C1EA40   C1EA56   CODE   N   Charm - stolen bit $40 and gets item reward index</pre>

(these last two lines are for resetting the enemy stolen bit in memory, so that
you can't steal the same item more than once from a single enemy)

Geiger

31.6% to be more precise (remember, 0 is also a success).  Yeah, ye olde Twin
Charm is not so hot.  But if the Charm Top still counts (and I am guessing it
does), the highest steal chance is 94.1%. Probably great for single charm
chances, like boss fights.

---

As for why its not much of an upgrade, with the Charm Top tripling the result,
the maximum value without overflow is 0x55.  A better solution would probably
have been to up the base result slightly, make Twin Charm more effective, and
only doubled the effect with Charm Top.

---

0C2A33 - Chance to get rare charm (aka normal drop)?

Code is a bit confusing, but this appears to be the value loaded and checked
against to determine if a Charm attempt results in a charm or rare charm.

For a 100% base Charm chance, use this code:  CC235C FF

==Pointers==

Pointers are at CD5EC6 (2 bytes each)
Data is at CE0380

The first attack and script is Crono's regular sword swipe, and I'm pretty sure these cover enemy attacks as well.

I think each script begins with 90 XX 90 XX (or something similar).

CE0000 - Pointers to Enemy Death Scripts (2 bytes each)
CED428 - Enemy death scripts (Hetake uses this script)

D10000 - Pointers to attack graphic effects (2 bytes each((the slash of crono's sword for example...))

CD686E - pointers to attack graphic effects palettes (2 bytes each)

==Notes on Tech Modification==

Party does Party techs (Difference from the one listed below is sometimes this affects certain enemies):
7EAE93XX (XX list Index A at bottom)
Certain moves may freeze or glitch

Enemies do Boss's Techs (Affects only enemies):
7EAEE4XX (XX can be anynumber mess around with it for different results)

Does move equal to XX( Affects only party):
7EB18CXX (See index A at bottom for list of XX)
Certain moves may freeze or glitch; Example is pogozo dance with anyone and magus, interestingly i think this is because he doesnt have a boggy sprite while all the other characters possess some form of dancing sprite.

Use Enemy Moves:
7EAE9106 (Certain moves may freeze or glitch)

Player 1 does all techs/atks no matter who selects commands:
7EAE9100 (May Freeze on some moves)

Player 2 does all techs/atks no matter who selects commands:
7EAE9101 (May Freeze on some moves)

Player 3 does all techs/atks no matter who selects commands:
7EAE9102 (May Freeze on some moves)

Always a critical hit for party:
7ECC8702 (Easiest to see with frog and chrono)
