XCOM Enemy Unknown Compression Toolkit

[fairchild]

Yet again a compression toolkit, this time for XCOM Enemy Unknown...

To use this toolkit you must first extract the savegame from within the xbox 360 container (CON), then use this toolkit on the extracted file. If you try to use this on the CON file itself it will give you a warning.

This is not a click 'n play tool, you need to use it from the Command Prompt or any other methods that handles this tool.

Release notes:

  Yet again a compression toolkit, this time for XCOM Enemy Unknown...

  To use this toolkit you must first extract the savegame from within the
  xbox 360 container (CON), then use this toolkit on the extracted file.
  If you try to use this on the CON file itself it will give you a warning.

  This is not a click 'n play tool, you need to use it from the Command Prompt
  or any other methods that handles this tool.
  
  Update:
   * v0.1.6 - Added support for additional security check for PC savegames.
   * v0.1.5 - Added support for PC savegames.

  WARNING!
  
  Always backup your saves, this tool may corrupt remove your savegames.
  

  Decompress
  ==========

  Now to decompress a savegame you run the application by entering the following:
 
  * <PTEF> = the path to the extracted files, ex: c:\test

  <PTEF>\xcom.exe -d <PTEF>\<my savegame filename> <PTEF>\save.decompressed

  Example: c:\test\xcom.exe -d c:\test\save1 c:\test\save1.decompressed

  The toolkit will process the savegame and decompress it's compressed data block 
  to the file names "save1.decompressed".

  Open "save1.decompressed" in your favorite hex editor :-)


  Compress
  ========

  To compress and inject the uncompressed blocks back into your savegame use the
  following command:

  NOTE: !! make a copy of your orginal savegame !!

  * <PTEF> = the path to the extracted files, ex: c:\test

  <PTEF>\xcom.exe -c <PTEF>\save1.decompressed <PTEF>\save1

  Example: c:\test\xcom.exe -c c:\test\save1.decompressed c:\test\save1

  This will take the decompressed block, named "save1.decompressed" and
  compress them, rebuild the package to a file named "save1.rebuilt".

  The file to inject back into your CON file is the file ending with ".rebuilt" !

  
  NOTE:

     Always make backup of your savegames!!

  Have fun :-)
