Decompressing and Extraction of Client Files

Ether Saga game files are compressed into .pck archives. To decompress and extract these archives a tool called sPCK is needed.

sPCK usage is quite simple. It takes an argument for the game, whether to extract or compress, and what file to work on.

sPCK.exe -eso -x surfaces.pck

Arguments for each game are as follows:

  • -pw - Perfect World
  • -jd - Jade Dynasty
  • -fw - Forsaken World
  • -eso - Ether Saga

You use -c for compress or -x for extract.

In the above example, we are telling sPCK.exe that our .pck file is from -eso Ether Saga and to -x extract the files from surfaces.pck

Extracting the files will create a folder called surfaces.pck.files that contains all the files extracted from surfaces.pck.

For convenience sake you can create a batch script called unpack.bat containing the above example and change surfaces.pck to whichever .pck you wish to extract.

Recompressing

To recompress the files you can simple switch the -x to a -c and pass surfaces.pck.files instead of surfaces.pck.

sPCK.exe -eso -c surfaces.pck.files

For convenience sake you can create a batch script called recompress.bat containing the above example and change surfaces.pck.files to whichever .pck.files you wish to recompress.
