is there any application so one can maybe drag over NSF's to the app's window and get the filename renamed to what it's named in winamp? i know there is one for SPC's atleast
If you're using a Mac, Game Music Box includes a nice utility window that can rename a whole directory of game music based on the title fields (NSF, NSFE, GBS, VGM, SPC, GYM). (Disclaimer: I wrote the program)
