Romhack, yes, I can add cubic easily. But right now due to time and cpu constraints, I'm going to use copy and update style resampling. Adding cubic resampling and on-the-fly rate changes to FBA soundcore is kinda tricky if you've never done it before, but after doing it dozens of times its simple for me. (although I couldn't say this a few years back..)
