For client versions below 2.0 you must omit the sending of packet 0xBF:0x06 which is the the"Map" packet. This fixed length packet is unknown to the client and will freeze the network stream.

Once in game, there are quite a few other packets that will need to be omitted. Any fixed length packets that are post client version must be removed. Most of the BF packets (if not all, i don't recall) are not supported.

You may find this packet guide from 2000 helpful. It does contain some post 1.26.4 packets, but it's a much better starting point than the modern packet guides:
