How can I edit rom name / description?

[¸Bero1707]

On my retroarch playlists some rom names are messy especially for rom hacks leaving author name in the rom name or sometimes names are totally changed so I don't reconize what game it is until I open that rom.
As far as I understand these names work like tags for music files so what software do I need to change some names and will this affect the ability to load old savestates for these games?



I found N64 rom renamer: http://www.romhacking.net/utilities/791/

If anybody knows something like this for NES roms that would be really helpful.
