Damage Identifiers

Damage Identifiers in Zelda 64 are an interesting matter. They are listed in what seems to be plain bytes

at first with, in this instance Din's Fire being Byte 11. However it's not as simple as it looks. There is

an instruction found at 62060 which is likely used for many other things which takes a raw value 00020000

and translates it into 11, how is this done?
Well it runs it through a Break if Not Equal at 0x6206C, which always matches a value of 0000001 against

it. When the value is not matched it is sent back to 0x62060 which is a Break If Equal instruction, where

it will run through this pattern until it reaches the 01, this is done by each cycle reducing the amount

in 00020000 in a bit sequence (meaning the valid values are 0,1,2,4,8 for each bit)
So it turns out that after 11 (in hex) cycles of this I found that the value that started as 00020000 had

become a 00000001. Once it reaches this value the instructions proceed unobstructed from there. This is

how damage identifiers and probably a lot of data is written. Knowing this now I placed a breakpoint on

0x6205C (the address before the cycling process) and noticed that instead of the register that held

00020000 (A0 for reference) I saw an address.
This may mean that you can find the location of what is going to be there by following the value in A0 by

breakpointing on 0x6205C, I followed that address and found where the value originated. The very temporal

file of Din's Fire.
In this case Din's Fire Damage Identifier Byte was 00020000 because it is 11 cycles in hex before it

reaches its goal. I searched ovl_Magic_Fire (Din's Fire file name) and found a 00020000 which matched up

mostly with the data I saw in memory. Changed it in ROM and changed the damage byte.

To any prospective hackers, keep in mind that what you may be looking for could possibly not just be a set

value. A simple 11 or 61 may not be as simple as that to access, but instead may take a completely

different form than you were expecting. I came into this expecting to find a blatant 0011 and be done with

it, I know now that it will not always be that simple.
