So I found a conspicuous-by-absence missing feature in the API of Game_Music_Emu, a library that blargg appears to no longer maintain (but correct me if I'm wrong). I've reported it to maintainers of various distributions of GME: kode54, mpyne, and the Ubuntu team. Here's what each report looks like:
When a library has become widely forked, what's the best way to get a simple feature request into all of them, especially the version that makes it into popular free operating system distributions' package repositories?
I am developing a music player and want to list all types that my music player's Game_Music_Emu plug-in can play. I can iterate through types with gme_type_list(), but all I can retrieve about each gme_type_t through the C API are the name of the console it's associated with (gme_type_system()) and whether the type supports multiple movements (gme_type_multitrack()). I'd like to be able to look up the most common extension associated with a track. I can go from extension to type (gme_identify_extension()), but not the other way around.
