Im trying to hack the security on a game so i can change the max credits when the game boots it runs a validation process and shows 2 hex strings.
SIGN=280d4b95aeb6cddb0c99033934070acc6c5516bf35268ba7a5fd156159b774d62666017c13ee5a58 This is the last part if the file when read in a hex editor.
SHA1=b33f8bfe9256203b5e67c0c9df71f89240c757da The sha1 of the file if the SIGN above is set to all 0
GAT2=d825d0ca5a6345bad6b772c5be03fa07d083769d The sha1 of the file with the sign in tact.
If i set sign to all 0 and boot the game it shows all 0 it fails verification and show sha1 and gat2 both matching the sha1 above and sign all 0.
Any idea what kind of protection this is and how i can crack it?
