Blargg's video game music emulation library, which allows audio applications to easily add playback support for the music of many classic video game consoles.
There is a set of BSD licensed chip emulators called YMFM which can be taken to here as an alternative to the MAME emulator (which is GPL licensed).
The only problem they require C++14 to build. So, it's possible to make the same as at the side of libOPNMIDI: do build it when C++14 is available, otherwise, don't build YMFM sub-module.
