Support Big Endian

[afxgroup]

I'm trying to add big endian mode to the game but i'm stuck at "try to detect correct method to decode data"
The signature is not decoded correctly most probably due the decodeUnbreakableXor
SHould _magicBytes[] reversed or i can use them in the same order are defined for little endian mode?
dataSize and dataOffset are converted correctly but the signature seems always wrong
