Confirmed on 9.04. The problem is the aoss alsa sound wrapper. See my
attached console output.
gfceu calls fceu through the aoss wrapper. When called with the exact same
command line options as through gfceu, fceu did not freeze through over 30
minutes of playing when called directly from the
FCEU freezes on my computer too using GFCEU (haven't tried otherwise), I
use 9.04 Jaunty currently...
Maybe it is related to sound system as with Ubuntu 8.10 Ubuntu changed
to PulseAudio and this is where hangs started to happend...
