10/12/2009 13:07 LemoniscooL#1
First of all, i havent tried this on the Dragonica files, but it worked in other games that are protected by GameGuard and HackShield Pro.


Hihow!
Again a trial on how to fix the CRC checksum of changed pe-files (exe & dll), as mentioned above, i havent tried it on Dragonica files but it should work.


What you need:

Step-by-Step:

  1. Unpack PEiD v0.95 anywhere on your Computer (e.g. Desktop)
  2. Unpack the CRC32 Plugin into the Plugin Folder of PEiD
  3. Start PEiD, click Options and make sure they are as folows:

    [Only registered and activated users can see links. Click Here To Register...]
  4. Click Save and restart PEiD
  5. Now open the ORIGINAL and UNCHANGED file in PEiD and click the Button named "->" (lower right corner of PEiD) choose Plugins->CRC32 and click it
  6. Now you will see a window like this:

    [Only registered and activated users can see links. Click Here To Register...]
  7. Copy the CRC32 value and close the Plugin window
  8. Now open up the CHANGED file in PEiD and open the CRC32 Plugin window again
  9. Now paste the CRC32 value from the original file into the "New CRC" field and click "Fix it!"
  10. Now close the Plugin window and PEiD

é voila there you go the CRC is fixed and your changed file should work

GameGuard checks the game files and his own files with a CRC checksum, with this you can fix the checksum of changed files. Its needed for gPotato ^^
