I'm starting up this thread again.
Battle Shit:
//if bit 1 is set, the character is dead, other status ailments are in this byte too, iirc
$6101 ;char1 status byte
$6141 ;char2 status byte
$6181 ;char3 status byte
$61C1 ;char4 status byte
//used during battle to determine the sprite set to use for each character
// #$00 - dead
// #18 - kneeling/status ailment set
$6AD6 ;char1 sprite position
$6ADA ;char2 sprite position
$6ADE ;char3 sprite position
$6AE2 ;char4 sprite position
//this draws the 4 windows that encapsule the 4 character's battle stats
$F2FE:A9 19 LDA #$19 ;stat battle x position for all 4 stat windows
$F300:A2 15 LDX #$15
$F302:20 C6 F3 JSR $F3C6 ;draw window
$F305:A2 0F LDX #$0F

$F30F:A2 03 LDX #$03
$F311:20 C6 F3 JSR $F3C6 ;draw window
Not Battle Shit:
//window calling routines for the shopkeeper screens. it appears this is called for every window draw and change in option.

A few more battle-related values.
Also as a note: the values I posted about that determine which battle sprite should be displayed for each character, (i.e. $6AD6 for char1) are not entirely correct. They work for all non-dead sprites. Non-dead sprites are chosen in a different manner from a different routine I have not yet located, probably because non-dead sprites are 16x48 (vertical) and dead sprites are horizontal (assuming, use at your own risk).
6AD0 - count-down for how long to display battle windows
0x2Da32 - how long to pause when displaying battle text windows,
put into $6BAC SRAM and stored into $6AD0 for decrementing
610A - current/calculated health for character 1

Back again, bitches. This time with some SRAM/WRAM values. These labels are valid when the Weapon and Armor menus are opened respectively.
upper bit (1xxxxxxx) set means the weapon is currently equipped, as denoted by the "E"/"checked"/"Equipped" graphic next to the weapon/armor piece.
$6118 - Character 1, Weapon 1 slot (upper-left on menu)
$6119 - Character 1, Weapon 2 slot (upper-right on menu)
$611A - Character 1, Weapon 3 slot (bottom-left on menu)
$611B - Character 1, Weapon 4 slot (bottom-right on menu)
$611C - Character 1, Armor 1 slot (upper-left on menu)
$611D - Character 1, Armor 2 slot (upper-right on menu)
$611E - Character 1, Armor 3 slot (bottom-left on menu)
$611F - Character 1, Armor 4 slot (bottom-right on menu)
$6158 - Character 2, Weapon 1 slot (upper-left on menu)
$6159 - Character 2, Weapon 2 slot (upper-right on menu)
$615A - Character 2, Weapon 3 slot (bottom-left on menu)
$615B - Character 2, Weapon 4 slot (bottom-right on menu)
$615C - Character 2, Armor 1 slot (upper-left on menu)
$615D - Character 2, Armor 2 slot (upper-right on menu)
$615E - Character 2, Armor 3 slot (bottom-left on menu)
$615F - Character 2, Armor 4 slot (bottom-right on menu)
$6198 - Character 3, Weapon 1 slot (upper-left on menu)
$6199 - Character 3, Weapon 2 slot (upper-right on menu)
$619A - Character 3, Weapon 3 slot (bottom-left on menu)
$619B - Character 3, Weapon 4 slot (bottom-right on menu)
$619C - Character 3, Armor 1 slot (upper-left on menu)
$619D - Character 3, Armor 2 slot (upper-right on menu)
$619E - Character 3, Armor 3 slot (bottom-left on menu)
$619F - Character 3, Armor 4 slot (bottom-right on menu)
$61D8 - Character 4, Weapon 1 slot (upper-left on menu)
$61D9 - Character 4, Weapon 2 slot (upper-right on menu)
$61DA - Character 4, Weapon 3 slot (bottom-left on menu)
$61DB - Character 4, Weapon 4 slot (bottom-right on menu)
$61DC - Character 4, Armor 1 slot (upper-left on menu)
$61DD - Character 4, Armor 2 slot (upper-right on menu)
$61DE - Character 4, Armor 3 slot (bottom-left on menu) |

With the character data in SRAM in hand, you can do some nifty things, like, for example:
//unequip all items owned by the first character; part of a job change hack i'm doing
LDX #$08 ;loads number of equippable items
prox:
DEX ;next item
TXA ;loads AC with item number
BMI saida ;if no more items to unequip, finish it
LDA $6118,X ;gets position of item[X]
BEQ prox ;if theres nothing in that slot, get next item
BPL prox ;if the item is already unequipped (<#$80), get next item
EOR #$80 ;unequip this item
STA $6118,X ;store it back
JMP prox ;go to next item
saida:
RTS

I have a few crappy notes from FF1. Very disorganized, portions are years old and wrong. Read at your own risk. |
