Inline Patching
1- Add Free Space == 00EEA00B

2- Find Real CRC32

CRC1 = D2B572BF --> [EBP-10]
CRC2 = FDF61F49 --> [EBP-18]
CRC3 = 97EF85E3 --> [EBP-1C]
CRC4 = BB989269 --> [EBP-20]
CRC5 = 4E45D7E8 --> [EBP-24]

Armadillo EntryPoint = 00EA841F

2- Patch Debug-Blocker == 00E5AE86
    
3 - ADD Free Space = 00EEA00B


4 - Write Inline Patching Codes
