I'm looking for some good ROM hacking utilities (completely legal) for the following games. Any help would be appreciated.

The list:

Super Mario Bros. for NES
SMB3 for NES (I have SMB3 workshop, and it's OK, but I'm looking for more if possible)

Legend of Zelda (NES)
Zelda: Link to the Past (SNES)

Metroid (NES)
Super Metroid (SNES)

I use and am totally happy with Lunar Magic for Super Mario World. That is the most excellent level editor/ROM Hacking utility I have ever come across.

I tried googling for info, and that's how I found SMB3 workshop, but couldn't find much else.

I haven't tried these, but: http://www.zophar.net/utilities/level.html

I saw that. Honestly I was looking for specific recommendations based on experience, as opposed to just a list of all available tools to wade through (there is a much more comprehensive list at romhacking.net, by the way).

We should have some sort of contest where we submit hacked Mario levels.

maybe... judging would be really tedious though. Maybe the goal could be to stump Not Sure...
