Help/Support Attack damage modification

jayvee · March 25, 2015

I modified an attack damage of my units on a game. I set it to 65k damage points. But in the game the attack damage reduced to 5 damage points. Here is my modification

Push{r4-r7, lr}

Mov r0, #FF

Mov r3, #FF

Muls r0, r3

Pop{r4-r7, pc}

I just dont understand why the attack damage got reduced to 5 damage points. Any explanation for this?

What is the hex value of push{r4-r3, lr}? My arm to hex converter is unable to convert it

Try looking at what the hex already is for PUSH {R4-R7, LR}. If you see a seven in there, try changing it to three. I use this method when modding instructions with the ".W" suffix

brave frontier? i know the max damage is 65335 or something like that

Why you use r4 and r7 ? When they are not used

FF * FF= 61665

255 * 255= 65025

Use bx lr or copy result to lr

sorry im a newbie in ida hacking. I just followed a tutorial in the other site. I even tried this:

Mov r0, #FF

Mov r1, #FF

Muls r0, r1

Bx lr

...but im still dealing 5 damage points per hit. Damage points for unmodified ranges from 500 to 3k damage points per hit

im not sure if you use #0xff instead of #ff, will it work? or you can use #255 if you wanted to
