Enemy List

These Pro Action Replay codes can be used to change the first two enemies that appear at the beginning of the first stage. Presumably, U.Andore and F.Andore would've used values 0603, 0604, respectively, but no slots are reserved for them.



Alternately, change the following values directly in a hex editor:


Enemy Index, Name
0300 Mic 
0301 Schot 
0302 Bull 
0303 Mark 
0304 Jack 
0305 Elijah 
0400 Elick 
0500 Atlas 
0501 Jony 
0600 Andore Jr. 
0601 Andore 
0602 G.Andore 
0700 Leon 
0701 Robert 
0800 Eliot 
0801 Elias 
0900 Joe 
0A00 Won Won 
0B00 Freddie 
0C00 Bratken 
0D00 Philippe 
0E00 Rolent 
0F00 Retu 

Enemy Names

The enemy names are stored in the chunk of memory beginning at 00016A4B and ending at 00016B9A when viewed in a hex editor. The data for a given enemy is 12 bytes long--the first byte is presumably a pointer to the enemy icon, but this isn't known for sure. Then there's white space, and finally the enemy name. In other words, the enemy names are left-padded with spaces. Note that the first three entries are currently not known as to what they actually are (Possibly encrypted data for displaying the player character names/icons?). "Plaintext" enemy data, therefore, begins at 00016A6F.

For example, to change Mic's name to Michael, you would change the row of data found at 00016A70:

20 20 20 20 20 20 20 20 4D 49 43 04 20 20 20 20 |        MIC.    |


20 20 20 20 4D 49 43 48 41 45 4C 04 20 20 20 20 |    MICHAEL.    |

Do not change it to the below. More accurately, while you can change it to the below, you won't get the results you expect--Mic will still be called Mic, while Schot won't have a name and will have gibberish for an icon.

20 20 20 20 20 20 20 20 4D 49 43 48 41 45 4C 04 |        MICHAEL.|

Player Character Stats

The following addresses correspond to the statistics for the three playable characters, their starting health, and their attacks. Numbers in parentheses in the comments are the corresponding decimal values.

When viewed in a hex editor, the corresponding beginning address is 00016B9B.

Enemy Stats

The enemy statistics begin immediately after the above player statistics (Viewed in a hex editor, beginning at 00016BD1). The format is as follows:

-The life of the "group" of enemies, in two bytes (Smaller byte first), for each of 32 potential "internal" difficulty levels. This takes up a total of 64 bytes.
-The defense of the group, taking up 32 bytes, one for each potential internal difficulty.
-Numerous groups of 32 bytes, presumably attack values for that group's various attacks.

The beginning addresses for each group are the following locations. Group numbers correspond to the first byte in the "Enemy Index" section above:

Group 03 (Mic/Schot/Bull/Mark/Jack/Elijah): 82EBD1
Group 04 (Elick): 82ECD1
Group 05 (Jony/Atlas): 82EDB1
Group 06 (Andore Jr./Andore/G.Andore): 82EEB1
Group 07 (Leon/Robert): 82EFF1
Group 08 (Elias/Eliot): 82F111
(Group 09, the Joes, do not seem to appear in this block. Perhaps their data is all hard-coded elsewhere)
Group 0A (Won Won): 82F1D1
Group 0B (Freddie): 82F2F1
Group 0C (Bratken): 82F451
Group 0D (Philippe): 82F5D1
Group 0E (Rolent): 82F6B1
Group 0F (Retu): 82F791

The structure of this enemy data implies at least the potential for an arcade-style "rank" system, despite the fact that there are only 4 selectable difficulties. How much of this is actually used, and how much is "Capcom ported the enemy structure from Arcade Final Fight to SNES Final Fight 1, then kept it rolling for Final Fight 2 instead of cleaning up that structure", is unknown at this time.

The Damage Formula

Determining damage to an enemy is pretty simple:
-Take the value of the attack in the "Player Character Stats" section above.
-Multiply that value by (32 - enemy defense)
-Divide that result by 32
-Round down, if necessary

Display 8 or 16-bit value

The programming to display an 8-bit hex value is used (by the continue countdown timer in 2P mode when one player runs out of lives), but not the 16-bit part. No pattern matches for 22468580 (JSL $808546) were found.
