Hi,

I just want to ask you guys about a weird CRC function that I've encountered.

First of all, I tried to see what accesses the address the I've want to modify. Strangely, every check there is a new function ( same instructions tho ) being written to the memory to check the address.

And it also has weird registers value. Because it shows that an instruction accessed it, but when I check the register values, it is way too off data. e.g I checked the registers and it doesn't contains the address that I want to modify.

By the way the game is protected in VMProtect. Does it has to do with it?

Thanks.

Yes, VMProtect virtualizes the code. Afaik this is the reason you have different access calls.

If it's the same instructions, try looking for the source and changing that.
