ZC is great, but i was wondering

Closest thing, at least that I am aware that is still in production, is Lunar Magic, however it edits the SMW rom. You should do a Google on Mario Classic and stuff like that and you might find somthing.

Thanks Jigglysaint....i went to lunar magic and saw something that gave me great hope....now if i find SMB 3 level editor i will be very happy, making Zelda and Mario....long sigh....

http://www.lincolnsoft.com/programs/mi3/ Mario Improvement 3. It's an SMB3 level editor, but it's a DOS program though.

I found a windows version of SMB 3 called Mario Discombulation when searching for SMB 3 editors....although no where near the quality of Zelda Classic!
