I have a game the scrambles the radar when entering a PvP Zone. I have managed to find the co-ordinates and player positioning addresses to nop, however i am having problems with the scramble itself.

Code:
.text:00007FF724B567ED                 mov     [rdi+8], al  -- nop here allows for position and location.
.text:00007FF724B567F0                 mov     [rbp+57h+var_60], al
.text:00007FF724B567F3                 mov     [rbp+57h+var_68], esi
.text:00007FF724B567F6                 mov     [rbp+57h+var_70], 0Fh
.text:00007FF724B567FE                 mov     [rbp+57h+var_78], rsi
.text:00007FF724B56802                 mov     byte ptr [rbp+57h+Dst], 0
.text:00007FF724B56806                 mov     r8d, 0Fh        ; Size
.text:00007FF724B5680C                 lea     rdx, aSetradarenable ; "setRadarEnabled"


Code:
.text:00007FF725924F8E                 mov     [rcx+0C0h], dx -- nop here will put enemy positions on radar
.text:00007FF725924F95                 cmp     byte ptr [rax+0AABh], 0
.text:00007FF725924F9C                 jz      short loc_7FF725924F6C
.text:00007FF725924F9E                 or      dx, 8
.text:00007FF725924FA2                 mov     [rcx+0C0h], dx
.text:00007FF725924FA9                 jmp     sub_7FF725924100
.text:00007FF725924FA9 sub_7FF725924F60 endp


Code:
7FF72597D05C - 49 63 6C 24 08  - movsxd  rbp,dword ptr [r12+08] (nop this and will crash)
7FF72597D1A3 - 48 8B 49 08  - mov rcx,[rcx+08] (nop this and will crash)
7FF72597CF34 - 44 8B 51 08  - mov r10d,[rcx+08] (nop this and will crash)
7FF72597D174 - 3B 43 08  - cmp eax,[rbx+08] (nop doesnt work but no crash here)
7FF72597CAE1 - 3B 6E 08  - cmp ebp,[rsi+08] (nop doesnt work but no crash here)
7FF72597CBD8 - 48 8B 56 08  - mov rdx,[rsi+08] (nop this and will crash)
7FF725925315 - 4C 8B 71 08  - mov r14,[rcx+08] (nop this and will crash)
7FF72592531F - 48 89 51 08  - mov [rcx+08],rdx (nop this and will crash)
7FF7259253C0 - 48 8B 46 08  - mov rax,[rsi+08] (nop this and will crash)
7FF72597CBE7 - 4C 8B 46 08  - mov r8,[rsi+08] (nop this and will crash entering pvp)
7FF72597D405 - 8B 79 08  - mov edi,[rcx+08] (nop doesnt work but no crash here)
7FF72597DA4A - 48 83 79 08 01 - cmp qword ptr [rcx+08],01 (nop doesnt work but no crash here)
7FF72597DA8D - 4C 8B 43 08  - mov r8,[rbx+08] (nop this and will crash leaving pvp)
7FF72597DAA8 - 48 FF 4B 08  - dec [rbx+08] (nop this and will crash)


One of these addresses will unscramble the radar, but i am not sure how to go about this. These addresses access the dynamic address which when set to 3 unscrambles the radar without crashing.

Code:
7FF72597CBD8 - 48 8B 56 08  - mov rdx,[rsi+08] (nop this and will crash)

Change to this?
Code:
mov rdx,3

Thanks for the information!

Code:
7FF724B567ED - 88 47 08 - mov [rdi+08],al (i changed al to 17 and thats all i had to do)


Didn't really need to change any other addresses after all!
