Step 4:
Change Binary string GameGuard to GameGuar2.
So select in binary String d letter wich is in HEX 64 to 2 wich is in HEX 32

So we right click on 64 number in HEX Dump tab and click on edit -> binary edit.

 Spoiler

And change 64 value to 32

and press OK.

Now you need repeat Step 3 and 4, just search again for binary string GameGuard and change it again.

Step 5:
Save EXE file. Right click on File window and press save.

Step 6:
Load Saved EXE file again in Olly and search for all referenced string.

Right click on Main CPU window and pres search for... then All referenced String.

Step 7:
right click on new window and press Search for text. In search window type n_protect.dat now you will see line where n_protect.dat is so double click it.

Then you will see some like this.:

Step 8:
Right click on that line and and press edit then copy to executable.

 Spoiler

Step 9:
You will see in new window line where n_protect.dat so click on it and press space to edit line in new window (assemble) change PUSH command to RET and click assemble. Then close next window what appeared.

 Spoiler

Step 10: Save EXE file same way as in step 5. And enjoy youre client without GameGuard.

Ps. All pictures are ilustrative, other clients then i use for example will have different adresses but strings will be same.

can you install the edited version of the gameguard fix?
