Help/Support Need some help for modding this instruction for one hit kill

[Guest]

I set my watchpoint, continued the game, and damaged an enemy. The watchpoint hit and GDB gave me an offset with the instruction VSTR S0, [R10, #204]. So logically I thought that I would NOP it to make one hit kill work. But of course I get EXC_BAD_ACCESS. But a NOP would be the only thing that would give me EXC_BAD_ACCESS. Here is what I have tried so far:

 

VSTR S7, [R10, #204]

I only did that because it would make the zombies in Dead Trigger a one hit kill, but in this game, it just made the health infinite.

 

VSTR S18, [R10, #204]

I did that because I saw somewhere that S18=80.0, but enemy heath was still infinite.

 

VMOV S0, R0

I did that because when GDB gave me the address R0 held something like -30. But enemy health was still infinite.

 

VMOV S0, R1

Same logic used with the one above. R1 held -100 or something like that, but it didn't work.

 

MOV R0, #0
VMOV S0, R0

I thought that if I moved 0 into R0 and then moved R0 into S0 enemy health would be zero, but it was still infinite.

 

MOV R0, #0
STR R0, [R10, #204]

Same logic as above, but I did not include S0 at all. Did not work.

 

If anyone can help me with this, it would be greatly appriciated

Like MOV R7, #data has 0x7F

Still not really sure what you mean, the original instruction was VSTR S0, [R10, #204] and there was not anything like VMOV S0, #x

I think I know what you mean. There are different enemies in this game so I'll just get get an offset from the biggest one.

I will tomarrow, it seems that that might actually work

The arm converter does not support VSUB, so I'm going have to figure out the hex myself. It might take a while, but I'll be sure to get back to you
