Storytime: Cucky's original SDL2 port work involved using SDL2's threading API to emulate the original WinAPI threading. I can't be assed with that stuff, so I used the same trick Cucky did for the Wii port, and hooked Organya up to the SDL2 audio callback. This actually opens up the possibility for perfectly-synchronised Organya playback. By that I mean, instead of needing a super low-latency audio callback, I can have the callback synchronise its audio mixing with Organya itself. I haven't done it yet, I plan to soon.
