[HELP] CRC Game

[jotatera]

Hello,

I wonder if I could help to solve a problem.

It is a game which has as protection CRC check, because when modified bytes, I detected.

Use the "stealth edit" plugin for cheat engine, and it works without problems.

The fact is that I want to do in a DLL, but not even know how to start.

Thanks for all the help you can give me.

Well you may start to learn some basics about DLL's first, instead of doing stuff which is above your level of knowledge.

Well, correct me if I'm wrong, but doesn't stealth edit just make a copy then route to that copy so that the memory checks aren't even checking the new copy?

If exact change only execute protection, and make the jump to another memory region.

Which bytes changed? In the game? So if you call WPM?

if when I change bytes protected.

not exactly.

if when I change bytes protected.

Maybe you could try looking for WriteProcessMemory hooks? Or BP some functions that could read the bytes e.g. RPM etc?
