All marked X are checked and activated in packet.c.
Here are the ones with an issue (I left them unactivated):
SP_ChunkData
SP_WindowItems (broken because of a small change to Slot struct in 13.2)
SP_SetSlot (broken because of a small change to Slot struct in 13.2)
CP_ConfirmTransaction (was not supported in the previous version)
CP_ClickWindow (broken because of a small change to Slot struct in 13.2)
CP_PickItem (didn't check yet since it's new)
