SDL 8-bit audio support

I'm currently porting Stella 1.4.2, and the only remaining problem I have is with the sound output. From what I can gather, Stella outputs an unsigned 8-bit audio stream, but when the emulator is run it sounds incorrect (like the stream is played back at 16-bit resolution).

Does anyone know if the PSP port of SDL has full support for 8-bit audio formats?

Cheers

Why not just add a simple loop to upconvert 8bit audio to 16-bit? You should have processing power to spare..

From my understanding of SDL audio, the SDL audio driver is supposed to automatically convert 8-bit to 16-bit (at least it looks like that's what it's supposed to be doing). I can take another look at it.
