This isn't really JCS related, but it seemed to fit best here. I'm sure that the Jazz Jackrabbit 1 tilesets are stored in their own file much like the JJ2 ones, and if not, within the levels themselves. If this is the case, I'm sure there's a way to view/extract them without requiring screen captures from the game. If this is the case, I'm sure that a tile extractor could be made. Then it would be easier to insert them into JJ2 tilesets or be used in other projects.

Please note that I haven't done much researchon this, it was just an idea I had. Still, it would be cool if the J2HG could make one.
