Hercules Renewal'd Pin Code

Feature is not, I repeat, NOT complete. the decryption is not fully functional which leads to dial values  different from the ones the player used.
Credits:
lemongrass3110 for the base
yommy for the packets
LightFighter for the decrypt function (altho its not stable :P)
