The "no-derivative-works" clause is a huge pain in the arse because that means we can't scale the sprites up, but that's a can of worms we can get onto later. The fact is, however, that Xsera is freeware, so we're not violating Lamont's Creative Commons license.
I may be incorrect, but from reading the announcement I believe that the "no-derivative-works" clause only applies to the movies.

The Ares Source Code
The media (text, images, sounds, and music) are distributed separately. Not all media from the original commercial distribution is included. Some sounds have been intentionally excluded.
The Ares Media
The movies are available under a more restrictive CC Attribution-Noncommercial-No Derivative Works license.
The Ares Movies
My reading of the above is that all media save the movies fall under the CC Attribution-Noncommercial-Share Alike license, which specifically allows you to "remix" the media for use in other projects. This strikes me as entirely workable - it's unlikely we would have wanted to remix the movies in any fashion, and most video players can upscale the resolution without altering the underlying file.
