Hmm dont understand whats going on

if i nop "mov [esi],eax" the value im trying to change dosent change good++ if nop the value freezes

but im trying to increase it and it dosent work, and i dont understand why.

i tried "mov [esi],999" and "mov [esi],fff" and "add [esi],fff" nothing as if the code is being ignored

also if somebody got time to explain the concept behind Push and pop


DarkSoulsII.exe+E2B50 - 55 - push ebp
DarkSoulsII.exe+E2B51 - 8B EC - mov ebp,esp
DarkSoulsII.exe+E2B53 - 8B 45 08 - mov eax,[ebp+08]
DarkSoulsII.exe+E2B56 - 56 - push esi
DarkSoulsII.exe+E2B57 - 8B F1 - mov esi,ecx
DarkSoulsII.exe+E2B59 - 39 06 - cmp [esi],eax
DarkSoulsII.exe+E2B5B - 74 5E - je DarkSoulsII.exe+E2BBB
DarkSoulsII.exe+E2B5D - 57 - push edi
DarkSoulsII.exe+E2B5E - 8B 7D 0C - mov edi,[ebp+0C]

DarkSoulsII.exe+E2B61 - 89 06 - mov [esi],eax
DarkSoulsII.exe+E2B63 - 89 7E 04 - mov [esi+04],edi
These 2 do it somehow---------------- inc and dec the value

DarkSoulsII.exe+E2B68 - 75 1D - jne DarkSoulsII.exe+E2B87
DarkSoulsII.exe+E2B6A - 6A 01 - push 01
DarkSoulsII.exe+E2B6C - 6A 01 - push 01
DarkSoulsII.exe+E2B6E - 50 - push eax
DarkSoulsII.exe+E2B6F - 8D 46 0A - lea eax,[esi+0A]
DarkSoulsII.exe+E2B72 - 6A 0D - push 0D
DarkSoulsII.exe+E2B74 - 50 - push eax
DarkSoulsII.exe+E2B75 - E8 960C0000 - call DarkSoulsII.exe+E3810
DarkSoulsII.exe+E2B7A - 83 C4 14 - add esp,14
DarkSoulsII.exe+E2B7D - 5F - pop edi
DarkSoulsII.exe+E2B7E - C6 46 08 00 - mov byte ptr [esi+08],00

Get the value of ESI at DarkSoulsII.exe+E2B59 (breakpoint)
Then find out what else writes to the address that ESI points at.

Any game? Some games have anti-debugger code and will kill themselves if they detect a debugger attached but there's generally settings you can change in CE to prevent detection. Even then most games don't do this.

Terraria, Starbound, Cave Story, Cave Story+, FTL, Borderlands, Borderlands 2, Amnesia, Aquaria, Bastion, Cube World, La-Mulana, Oblivion, Rogue Legacy... all of those games, I can attach to fine.

Show us your debugger CE settings?

Try on the tutorial and check if that also crashes.

Also, try page exceptions

Serious question, not trying to be funny or mean: what do you think a breakpoint is/does?

Well i thought the game/program goes back to normal after you turn it off..
I think i used breakpoints only in olly years ago when i didn't understand much, to check if the address has anything to do with what im doing.

Also this
