Modding Santa Claus In Trouble (XPK Tool)

A brief history...

In 2019 I started my studies in reverse file engineering and a good way for you to practice your knowledge is precisely to create tools to unzip and compress the studied formats.

Well, after analyzing some file formats, luckily I found a game that was part of my childhood: Santa Claus In Trouble. You may not be remembering, but I believe that most of you must have played it too... I confess that I was surprised, I played it when I was about 8 or 9 years old and I never thought I would play it again.

So I decided that I would do a packer/unpacker for the game's .XPK files.
It's a simple format, it's not compressed or encrypted, which made things a lot easier.

Game files
When unzipped, we will find files in formats already known and ready for editing, such as:

  • .DDS for Images
  • .TXT for configuration files
  • .WAV for game audios and music
  • .X for DirectX files - very old format
  • .TLB for text files and game translations
  • among others...

As a result, I ended up creating a tool that works not only for this game but for 2 other games from the same producer. They are: 

  • Santa Claus In Trouble (2002)
  • Santa Claus In Trouble... Again! (2004)
  • Rosso Rabbit In Trouble (2004)
Source Code Download Tool (14.34 KB)

It requires Microsoft .NET Framework 4.7.1 runtime to work properly.



  1. Hi, unfortunately the link to the modding discord isn't working anymore... can you maybe provide a valid invite link to the server? I might have found something interesting in the game's files :)
