This is no bug, pol99 uses the seedkey to inform the gameserver which clienttype connects. (needed for newer clients)

The seed key cannot be the problem its usually a random value, but most emulators just set it to a fixed value.
You can try it yourself by hooking the pkt and change it

On OSI they usually send the client IP as the key with this packet

and the client responses using the same key in packet

Code: Select all

Notes

Most of the emulators send it as FF FF FF FF
Pol uses it to recognize client type ( KR, SA ..... )
This key is and have always been there and it doesnt matter what values you send in it, so it can not be the problem you have
