> hi, I downloaded the Mod Creator 1.09, and I've got a question: What's the use of the "side 1", "side 2" and "side 3" category? They're not explained on the Mod Creator's Page? (Did someone not update it, when the new version came? :D :D )

No, I didn't update it ;->
You can use those categories for files that are side-specific, such as sidebar graphics.
