@jor2404 hello,
as you guess it, the Pi4 is not powerfull enough to launch PS2 emulators. A PC is required.

Hi, thx for your answer.
I am using Amyberry emulator and I've changed settings on sound emulation, reducing bit rate to 22000 for example, or reducing a bit the buffer value (too low give you a weird sound) but as I said in my post I didn't get good results with that.
My games for Amiga are disk images (ADF format).
When I try PUAE, some games have problems to load and give me the "Guru Meditation" error, games which load without problems on Amyberry or FS-UAE emulators.

Could you tell me your Amiga emulator configuration? So I can try

Thanks in advance
