I took a quick peek into the source, and it looks like this is where those OpCode errors you found are spit out:

zone/client_packet.cpp:
Code:
  375 	case CLIENT_CONNECTED: {
  376 		ClientPacketProc p;
  377 		p = ConnectedOpcodes[opcode];
  378 		if(p == NULL) {
  379 			char buffer[64];
  380 			app->build_header_dump(buffer);
  381 			mlog(CLIENT__NET_ERR, "Unhandled incoming opcode: %s", buffer);
  382 			if(app->size<1000)
  383 				DumpPacket(app->pBuffer, app->size);
  384 			else{
  385 				cout << "Dump limited to 1000 characters:\n";
  386 				DumpPacket(app->pBuffer, 1000);
  387 			}
  388 			break;
  389 		}
  390 
  391 		//call the processing routine
  392 		(this->*p)(app);
  393 		break;
  394 	}
You could relatively easily put some code in there to spit out the OpCode info to the terminal (cerr is used elsewhere in the source). Then again, looking just above the above code, someone already has:
Code:
  337 	#if EQDEBUG >= 9
  338 		cout << "Received 0x" << hex << setw(4) << setfill('0') << opcode << ", size=" << dec << app->size << endl;
  339 	#endif
  340 
  341 	#ifdef SOLAR
  342 		if(0 && opcode != OP_ClientUpdate)
  343 		{
  344 			LogFile->write(EQEMuLog::Debug,"HandlePacket() OPCODE debug enabled client %s", GetName());
  345 			cerr << "OPCODE: " << hex << setw(4) << setfill('0') << opcode << dec << ", size: " << app->size << endl;
  346 			DumpPacket(app);
  347 		}
  348 	#endif
So, you could set EQDEBUG=9 to get console output of what looks to be all of the OpCodes. This is done in the zone makefile before compiling:
Code:
   15 DFLAGS=-DEQDEBUG=5 -DCATCH_CRASH -DNO_PIDLOG -DSHAREMEM -DSPELL_EFFECT_SPAM -DFIELD_ITEMS -DCOMBINED -DAPP_OPCODE_SIZE=2 -Di386
If this works, I might put up a VM server to use locally to dig out some OpCodes. It sure beats packet sniffing + creating/fixing a program to decode it all Then, we'll just need to figure out the packet structures if we don't have them already.
