ROMS listed by categories...any links?

[End]

Is there a site that has MAME roms divided by categories and has screen caps?
I don't care about download.
I'm looking for some games played with lightgun , but I don't remember the names.

You can get the names by clicking the lightgun catagory in mame and get a screenshot pack for pics...or search the names here http://www.klov.com/
