I struggled with this same issue last night. Couldnt figure out why SOD just hung.

So I woke up this morning and realized my minilogin is in a subdirectory of eqemu. Once i updated those opcodes SOD connected just fine. Make sure you are updating the correct opcode file :)

This was driving me nuts too but then I changed the opcode.conf in both the eqemu directory and the minilogin directory and then it worked fine.

I just wanted to say thank you for this thread, it solved my problem.
