Mais pour l instant l émulateur n est pas au pt (source :http://ps2emu.dcemu.co.uk/uae4ps2.shtml )

Unfortunatelly the PS2 is not capable to run Amiga emulation
at full speed with no-frame-skip and sound enabled. The sound emulation takes about 30% of the proccessor time (of the ps2) so it is better to turn it off.
If you really want to go with sound enabled, buy a Xbox :-). Have fun!

Voilà
