Where Does It Display List/menu Of Roms To Play? Options

[cricket]

I'm looking through the mednefenx source, I want to make some changes to the mendefenx-nes emulator, specifically to the menu & part where it lists the avail. roms to choose and launch. Could someone point me where this is drawn/algo for this is in source?

Correct me if I'm wrong but it seems that all of mednefenx projects are thrown into one, so I'm not really just looking at mednefenx-nes source but everything else that mednefenx is a part of too...

Also, I predict I will have many more of these types of questions about where things are in the source. It would be nice if someone could document some kind of structure hierarchy of these emulators and their source.. so it helps noobies find their way around. A search can lead to specific strings in the source, but won't suffice to what a doc would say about "how everything works together and purposes of diff. things." Especially, if you don't know what to search for.
