Hi. So I have a memory address and it is getting accessed by this instruction:

bug in old ce
just look at the next instruction

also make sure editing a value has an effect in the game before you debug, this usually happens on display values

Thanks for the reply sir.

I checked there is no instruction around that instruction which access the same memory.

As far as bug in old ce is concerned, I am happy that its a known bug but have not checked with newer version. Can you tell me the version in which it was fixed. I can't check change log for each version after 6.8.1 as a human.

Its also a value which affects the game.

And even if its a display value, the debugger should find the instruction which is accessing it or modifying it. That is the expectation.

rep movs* accesses memory as well

Hi,

No, even those instructions are not showing what memory address they use.

I just tried with CE 7.5 and I see the same problem so even if its a bug , its not resolved yet.

Really need help here.

Also I can tell you that the memory I am trying to access is a very big memory region. All of them are getting accessed by the same instruction but the values in the memory region are diversified. I can see 0.5s,0.07s to 1500 to 7500 or -400 or -456. I am not sure how much this will help with understanding my situation but..

The instruction has an address "vcruntime140.memcmp+E8"

Post the code around the instruction CE thinks is accessing an address.

I'm almost certain it's some string instruction (e.g. rep cmpsb) and you haven't looked up what that instruction does yet.

since the instruction is memcmp I'd have to guess it's rep scas* then

But how can I see which addresses are getting accessed by this instruction? Coz when I tried "what address this instruction addresses", it showed nothing.

1: set a breakpoint at VCRUNTIME140.memcmp+E0
all addresses from rcx to rcx+r8 will get written and all addresses from rdx to rdx+r8 will get read

2: you don't want to, this instruction is a generic copy mem function

you'll have more luck with the s or ipt button to show the trace at execution time
