Thanks for the response.
I know when a beta release is make some trouble.
I will try a lot solutions (I am old user and I till now never get issues again) but without results.
My main problem is when a choose any game for any platform when a press the button to get in automatically return to games menu.
And secondary i don't get sound.
When I choose internal storage device all works smoothly the same when I got back to stable version.

Hi.
When I get first boot after installing new beta the existing games works fine... But when I choose usage disk with roms bios etc I can't start any game.
If turn back to stable version everything works.
