This is an archiver I've created, and it looks quite stable so far.

The PackMakerLite (PML) supports type 0-1-2-3-4-5-6.

As a summarize, the metin2 types are handled like this:

• Type 0 - only storage (no encryption/compression; it can be read fully from the .epk)
• Type 1 - compressed - lzo(file)
• Type 2 - compressed and encrypted - xtea(lzo(file))
• Type 3 - encrypted with Panama - you must save an .iv key server-side in the panama/ folder. (content readable only after auth phase) The official used it only for patch2.
• Type 4 - encrypted with a mix of ciphers (cshybridcrypt) - you must save a .dat key server-side in the package/ folder. (content readable only after auth phase) Practically all the metin2_patch files.
• Type 5 - like type 4, but a server-side map/<map_name> is also provided. (content readable only after accessing the <map_name> map as a player) The official used it only for the catacomb data.
• Type 6 - compressed and encrypted - xtea(snappy(file))

 

Usage:

Its settings (xtea keys, extensions, pack types to use) can be changed inside PackMakerLite.json:

updated:

 

You can actually integrate the tool in the menu context (running the .reg files) for packing folders and unpacking .eix files:

Remove "--nolog" from the .bat files if you want to see the logs again.

Command-line options get overwritten by JSON config options.

Last but not least: since the client handles all the filenames in lowercase, this tools automatically converts them as well.

So this is useless for people who use FOXFS or people who removed panama & package & hybridcrypt from their source ?

After packing with type 6, it doesn't unpack, I get: LZObject: not a valid data

 

Will you ever add lz4, specially lz4 hc?

In the last update, i've implemented the multithreading in the archive. It's currently extremely fast.
For packing, what it took 180s now is done in 5s.

For unpacking, what it took 180s now is done in 30s if the folders are missing, otherwise 6s.

i.e. I also improved the original single-thread algorithm so it's faster than the older versions.

 

I noticed 2 weird things though:

1) On parallel mode, some prints are skipped, so if you need to debug something, disable both --nolog and --parallel.

2) Redirecting the output to file (>.txt) on parallel mode slowers the process as if it were single thread back again.

 

FULL CHANGELOG
v1.3 added install.bat for installing everything (must be runned as admin)
v1.4 added "force_filename_lowercase" config field
v1.5 fixed packing of non all-lower-named packs
v1.6 fixed extraction of 0kb files
v1.7 fixed extraction of 2-len packs names
v1.8 fixed packing/unpacking files/folders with spaces in filenames (issue present only in the .bats)
v1.9 added type6 and header mcsp decryption
v2.0 added "ignore_full_name" config field, and allowed writing comments inside the .json setting file
v2.1 added "eter_magic_mcoz","eter_magic_epkd","eter_magic_mcsp" fields
v2.2 added "parallel" in .json, and --parallel as argument for multithreading packing/unpacking
v2.3 added global .json load from %userprofile% if the local ones are missing
v2.4 fixed type6 unpacking in parallel mode
v2.5 improved parallel speed when packing by 20x
 

[Hi. 93]

Very fast on packing and unpacking, but with version(this version i have) 2.5 it breaks the property folder.

[valdirk2 117]

Could you add the output function?
I wanted him to unzip the files in another folder, which I can select via the command line.

I find it somewhat disorganized to leave the files unzipped inside the pack folder of the client.
