The USF plugin (N64) for audacious
The plugin was removed sometime in 2012 (i think) from the audacious-plugins repo.
Then lucashpandolfo forked and restored the plugin (https://github.com/lucashpandolfo/audacious-plugins).
It was further forked and made compatible with Audacious 3.8 onwards by Sascha Klick in 2018 (https://github.com/saschaklick/audacious-usf-plugin).
In 2025 it was fixed again to work with Audacious 4.3.2 by switching to CPU interpreter instead of recompiler.
The plugin uses an out-dated Project 64 core. A simple drop-in replacement of a newer version of the core is not feasible, but still possible.
Games that did not work with the core in the mid-2000s will not have their USFs play in the plugin. Conker's Bad Fur Day is such a candiate, Blast Corps might be too.
There are newer USF sets marked [fixed]. These actually do not work with the plugin and produce garbled and sped-up audio. The non-fixed versions of the sets work though.
