Locate some ASM for me plz?

[zahlman]

As many of you know, I'm a programmer, but I don't really have meaningful experience with reversing ASM.

Anyone happen to know offhand where the routines are for damage calculations? I have no doubt about my ability to determine what they do currently or how to alter them (I have an idea for a hack) but I also have no real idea of how to go about locating them in order to make the changes. Ideally I'd like to replicate this for 6, 7 and 8.

TIA

I have some notes on battle calculations in my doc (I'm not going to tell you read it). Here's a copy-paste from it:

08028fb0-9022

-sub 08028f84 prepares the place for battle data

-sub 08029028 stores battle unit to r0 and r1

-sub 080290b8 (makes attack data)

-sub 0802903c (r0=ptr to attacker,r1=ptr to defender) returns 1 if weapon effect is 3

--08017424: loads weapon effect

--080290b8(r0 = attacker, r1 = defender)

---08029114(returns 2 if hero, else 1)

----08029128 flags battle data and returns 1 if hero, else returns 0

---080294d8(r0 = attacker, r1 = defender)

----080294e4-ee flags attack data if defender counter attacks

08029234 r0 = PtA, r1 = PtD

stores attack related data to 0203a3d8

08029324 r0 = PtA, r1 = PtD

checks for triangle attack

08029264 r0 = PtA

determines chances?

080285a8 r0 = hit, r1 = 1

return 1 if hit, else 0

08000e84

08000e04

08000be0

0802857c r0 = crit, r1 = 0

08000e60

08000e04

0802939c r0 = PtA -> r5, r1 = PtD -> r7

does weapon effects

08017424 loads weapon effect to r0

0802857c

08016730 lessens weapon uses

returns 0 or 1 in r0

It doesn't directly tell the offset you are looking for, but since it's in a file labeled "makes battle data.txt", I'd assume it's there somewhere.

Those are for FE7? (I'm guessing that a lot of the code will be shared, at least between 7 and 6, so I can search for it once I've found some reasonably unique patterns of opcodes)
