Black screen after loading

[gothrek]

Hi,
i have this prob, everyday i do the same, stop the emulator and copy roms, and start again.

Well today after start again, and after loading screen i see al black.

I dont change nothing and i can access by ip to the recalbox.
I try to restore the conf, and reboot, and we start again with the conf template.

Nothing always black screen after loading (now i can read the loading screen in english, before in italian).

Any ideas? There is a possibility to restore o.s. without losing roms etc? i use an sd.

i can access to recalbox by ip, windows, putty in ssh and winscp.

tks
