LiveCPK makes it possible to replace game content at run-time with content from files stored on disk, instead of having to pack everything into CPK-archives. (This feature is similar to Kitserver's AFS2FS and to FileLoader for earler versions of PES). Depending on how and when exactly the game reads the replaced files, you can even live-edit some things, like textures or 3D models, without exiting the game.
If you know a little bit how to program, you can write your own game logic using Sider's scripting engine. This requires some reading and understanding of how the game works, but it's really not that hard ;-) See scripting.html - for detailed documentation on that.
