Reading through this somewhat inspired me to continue my game using Jazz 1 tilesets/planets, but with Jazz Advance characters/enemies/sprites.
Speaking of which: There is a user called Dolphman, from a forum I visit called Pixeltendo he is currently making a Knuckles Vs. Jazz Jackrabbit game(With a pretty nifty edit of Marberla) I redirected him over here a while back, but he has been having problems, and it won't let him post.
