I'm feeling rather proud of myself this morning, I found the OP_Charm opcode for Titanium.

I read the Wiki pages that Trevius posted links to a couple of weeks back about using IDA to Disassemble the client
and find Opcodes.

E.g.: http://www.eqemulator.net/wiki/wikka...DevAsmRoutines

I don't know x86 assembler, however I have programmed in 6502 and IBM Mainframe assembly in years gone by, but I
still thought that finding opcodes through disassembly was 'out of my league'.

Well, I downloaded the free version of IDA, and disassembled the 6.2 client. Armed with the 6.2 Opcode, and with the
pointers to the dispatch routines and general methodology outlined in the wiki, I found the Charm routine in the 6.2
client.

I then disassembled the Titanium client and tried to find the same routine there, which I did. I then traced this back
up through the call tree and voila, for Titanium, OP_Charm=0x12e5. Just change this in your patch_Titanium.conf on the
server and restart it.
