Tibia update protocol.txt

Informaton about how Tibia updates itself
by tulio150 - tpforums.org

Thanks to:
Tibia's own debug assertions
Tibia Time Machine

This could be used to:
-One could make a mirror server when Tibia is updating, because cipsoft's always get down
-A server which you can download any Tibia version using the client
(Ex: login with acc tibia861 to replace your client with Tibia 8.61)
-OTServer: login with a certain acc/pass to download a custom client
-OTServer: custom graphics for each account (rank system, premmy/free, gm)
-OTServer: real updates
-Custom clients: get Tibia dat/pic/spr on-the-fly

Bad things people can do with this knowledge:
-Sending a new patcher followed by a dummy patch to make Tibia launch a virus
-Enforcing a custom client
-Update player's graphics without his knowledge

To-do:
Where Tibia stores the downloaded data
How the patching works after everything is downloaded
Patch file format

-------------------------------

ID 0x1E = Patch
ID 0X1F = Whole file
[1 byte ] Patch type
[4 bytes] Data size

Patch types:
0 = Tibia.exe (program version)
1 = Tibia.dat (object data)
2 = Tibia.spr (object graphics)
3 = Tibia.pic (pictures)
4 = Patcher.exe (patcher) (0x1F only)
5 = linux showerror file (??)

--------------------------------

ID 0x20 = Update data
[2 bytes] Block size
[x bytes] Block

Obs: Tibia server sends blocks of 10kb (10240 bytes) at a time

--------------------------------

1E / 1F records
