I tried searching but could only find bits and pieces.  Does anyone know what packet is received that notifies the client that Diablo Clone is present.  If I researched correctly, it would be in 0x89 and would be event 0x5A?

Any help appreciated!

The event is in packet 0x5A

And 0x5A format:
[code]
(BYTE) Event ID
(BYTE) Action Type
(DWORD) Player ID
(BYTE) Entity Type
(VOID[16]) Char Name
(VOID[16]) Account Name
[/code]
The player ID will be the soj count, if its a sale/walk event, other wise the other values can be ignored for those dc events.

hope this helps

Aha, it does, thanks.
