Hi

I have a question about copying a value from an address here's my example:

Two things based on what you gave so far would work:

1. Determine what calculated EDI. Typically before the line you are at, there may be a calculation that was done with EDI being the result register. Something like..

mov edi, [eax+0C]
dec edi
mov [eax+0C], edi

Not to say this is the exact flow of what is happening in your situation but find that calculation to determine what is happening.

2. Use the original value, if possible. Since the target is overwriting the value inside of [eax+0C] try just resetting EDI to that value. Such as:

mov edi, [eax+0C] // do this yourself
mov [eax+0C], edi // original code afterward..

Lastly would be just nop'ing out the instruction altogether if that is possible in your situation. Hard to say though since you did not show much asm.

Okay the 2nd suggestion you gave was perfect that works. Just so I make sure I understand this, you are taking the value from [eax+0C] and copying the value into edi. So edi gets added back into [eax+0C] when you reload. Makes perfect sense to me. Thanks a lot for clearing this up!
