How Do You Make Custom JJ1 Tilesets/Sprites?

[Love & Thunder]

I just got J1E, and I'm getting the full version of Jazz Jackrabbit CD very soon(CliffyB told me where I can get a copy legitimately), so I just have a question about J1E - How do I make custom Tilesets and Sprites for JJ1? At the moment I have the Shareware version and both Holiday Hare versions and I'll have JJ1CD very soon, so if any of your solutions require a specific version, just let me know.

You can make custom blocksets with J1E alone (File-Import), but for anything else, yeah, you'll want JJ1MOD.
