Ok for some reason I have been looking for level editors to games that normally wouldn't have one. I guess I'm just facinated by any kind of game customization.
So far:
Lunar Magic (Super Mario World): http://fusoya.panicus.org/lm/
Jazz Creation Station (Jazz Jackrabbit 2): http://www.jazz2online.com/J2Ov2/node.p ... e=jcsIndex
Can you guys think of any others?
