How does the old official metin2 torrent patcher work?

Hello all,

I'm trying to figure out how it used to be possible to bypass the old torrent patcher from the official Metin2 and start the client without a patcher.

The reason why I want to start without the torrent patcher is that I have created a language pack for the official Metin2 Brazil and the community often has the problem to use the language pack because the patcher updates the changed files again. I can't figure out what the patcher does in addition to generating the key using the date/time.

I already have a batch script with which I get the client started partially without problems. However, I must have started the client every 2 minutes once with the normal patcher, because this still changes 4 in my opinion dummy files in the client. If I started the client at 15:00 with the patcher normally, then I am able to start the client with my batch file without the patcher until 15:02. After exactly 2 minutes I have to run the patcher again to make it work with my batch file again. I see that after each patch operation the following files are processed:

/lib/xml/dom/minidomer.pyc
/lib/xml/parser/invers.pyc
/pack/metin2_patch_nodelar.eix
/pack/metin2_patch_nodelar.epk

At least the .eix and .epk files I can't unpack with PackMaker unfortunately.

The batch script looks like this:

@ echo off
echo 116807 >> 003254
set /a key = 781072347 + (%TIME:~3,2% * 2) + 2
metin2client.bin %key%

Does anyone know what the patcher does additionally and why I can't start the client with my batch file after two minutes?
