Decided to give Ubuntu another try once Karmic was released. Performance in general is terrible on DOSBOX and ZSNES (haven't tried any other emulators yet), but the sound is especially atrocious. I was able to fix the sound problems and speed up ZSNES a little bit by doing some tweaks I outlined on my blog here, but I'm still not really satisfied...I'd like to be able to get some more speed out of DOSBox and some sound that isn't lagging by half a second. What have you all done to make your emulators usable (if you've had problems)? Using a 1000HA, btw.

hmm, ive never had problems with znes, the speed is good and sound quality good as well, what exactly did you experience?
Offline
Any sample rate above 22050 Hz produced constant buffer underruns for the sound, so it sounded extremely choppy. The video performance was okay at first, but improved when I switched to an OpenGL mode.

well i think my znes installation came with openGL mode enabled by default, i checked it and it was on, as for the sound, i really cant think of what might cause the choppiness, ive used znes on various distros and have never encountered a sound problem.

Maybe you solved the problem already, but I have to pieces of advice for you:
A) Replace libsdl-alsa with libsdl-pulseaudio to remove choppy sound on almost every app using sdl. That would include almost every emulator for linux.
B) For zsnes, you also need to run it the first time from the terminal: 'zsnes -ad pulse'
Dosbox, however, still isn't quite working, it sounds as if the music is skipping notes or even playing random notes from time to time. I still need to do some fiddling with the midi settings of dosbox to find an adequate solution.

It can't even initialize the MIDI on mine. Thanks though, I'm going to try those things. I thought pulseaudio was buggy compared to ALSA though?
Offline
Pulseaudio works like a charm with ZSNES. Thanks Luis.
