MShield Client Protection (FREE)

small example of how cheats manipulate the client. Once you understand this, it's much easier to see how to defend against these modifications.

What does this cheat do?
It applies a no-collision / wall-walk patch.

The cheat replaces three conditional jumps:

0x73 (JAE) → 0xEB (JMP)

As a result, CTerrain::isAttrOn (AreaTerrain.cpp, line 488) always returns false, effectively bypassing terrain collision checks.

0x002cdd36:73>eb,0x002cdd3b:73>eb,0x002cdd55:73>eb

MS_CRC_V : d8d36171
MS_CRC_A : 2b944e96
MS_SYM : CTerrain::isAttrOn + 0x16
MS_SRC : \_src\gamelib\areaterrain.cpp:488
MS_ORI : 7335663bc173300fb7c173300fb7c8c1e10803ce0f
MS_CURRENT : eb35663bc1eb300fb7c8c1e10803ce0f

The log clearly shows the three JAE (0x73) instructions being patched to JMP (0xEB), changing the function's logic and disabling collision validation.

-------------

++ since the anti-cheat is performing really well in many other countries and servers, and the people I offered it to completely free of charge weren't interested, it will be paid from now on. There will be no more free access. 

I tried. 🙂 But it seems you can't help anyone for free here in Hungary. So I hope every Hungarian private server ends up full of cheaters, and everyone keeps paying unnecessarily for CShield and similar "protections."

Good luck. BYE
