I had the opcode errors as well, I copied and pasted the names of the missing ones from the world.exe window into the opcodes.conf file and just zeroed out the values. No idea if this worked, the error didn't come up, but on to my next issue..
I tried both the eqdr2 db and the peq db, and I can't get either one to work. The eqdr2 db spits out a bunch of errors in world.exe, and then says "make sure you sourced utils/items-0.6.0-DR2-0.6.1-DR1-convert.sql" I have no idea where to get this file. I'm not even sure if this db works with 0.6.2, but at least it lets me load up the zone servers.
I also tried the peq db, and I get no errors from world.exe that I can see, but when I run boot5zones.bat they immediately crash.
I'm just stumbling my way through this, but I'm close, I can feel it. I guess I'll just keep plinking away until someone figures it out. Where are those PEQ guys, they have a working server
