Error with OPCODE 623 turns 620

[ArmoredTrix]

I'm making a server and I'm having trouble PROTOCOL_BASE_DAILY_RECORD_ACKI put the opcode 623 correctly, but turns 620 in the game because of the last byte of the package. Could someone let me know how this works?

Can you better explain this? I don't get what you mean.

I'm creating a current version PointBlank emulator (3.58), analyzed the server packages and came across something different, the opcode of the packages are changed based on the last byte, example:

GameSend packet: 622
ServerSend Packet: 517 and the last byte 0x64 (in-game will perform the actions with opcode 623)

Is there a formula to predict these changes?

I've not worked so much on the the last version, but I remember that the packet from server was sended encrypted with a bitshift.

Yes I decrypted the packages and I can read the data but the problem is the opcode that changes according to the last byte...
It seems that there is a calculation in the game just for the opcode...
