thanks a lot. Changing the audio plugin worked for me too.

Mine is not overclocked, I can kill the Emulator- process, when I ssh the recalbox, so I think its not a hardware problem. I allready changed the Power-Adapter but I guess its not a stability problem. I also tried changing the plugin in the recalbox.conf in n64.core=n64, but that as well did not fix the problem. Any suggestions?   By the way: Except this little bug I really like Recalbox, easy to handle, working very stable, nice design!

Same here, I also changed the graphics plugin in the recalbox.conf , but it still crashes after some minutes.
