[CrackMe 2016] Delphi itself checks

[Reasen]

Difficulty : 4
Language : Delphi XE8
Platform : Windows x86/x64
OS Version : XP and above
Packer / Protector : None

Description :

I made my own CrackMe with a function to check opcodes by itself and i used it as the key to decrypt 2 variables, (cracked or not cracked),

the objetive of this CrackMe is to get the good boy message and not the "mal-decrypted" one.

Included in the zip file, original crackme exe, cracked crackme exe, and a write up explaining how to crack it. The main thing to patch is the self check and then its smooth sailing from there.
