Nerrazzuri. What do mean by accessing the random address?

Any address in between the crc region.

Edit: Now it works for me, BUT CRC scripts and debuggers WON`T work. The MSCRC won`t work AT ALL. Sigh~
The bad side of the bypass: I can only use softkeyboard to login. Keyboard is locked on login page and 2nd password enter page.

You mean the 2nd crc check??

Get ready for a Hackshield update sooner or later.

Wundows 7 SP1 will be out to the public in a few days time, to prevent compatibly issue, Asiasoft will have no choice to update their Hackshield to the latest Rev which support Windows 7 SP1.

So just about time this bypass would be gone.

Frankly speaking, I don't think Hackshield CRC will be patch. Hackshield always has problem with Vista and 7, Windows upgrade will not affect Hackshield and I believe Hackshield wouldn't put much effort in it only for Maplestory.

Also hooking these APIs not only disable CRC check, but also disable detection of hacking tools, as long as people don't abuse it, Maplestory will not bother to patch them.
