@gnubit la unica solucion que encontre fue esta . Pero cada ves que entramos hay que ir a kodi y salir...y queda dicha resolucion..mi maxima resolucion es 1680x1050

I'm on my pc using usb bootable key.
I have :

in the menu, sometimes it would hang for few seconds (no possibility to go up or down or push any button). some times i press a button or a direction on the pad nad it crashes and displays a black screen with "Loading REcalbox" which never ends.

I never had that with the previsou version. I tried two different usb keys with fresh install on two different computers.

The problem seem similar to that guys

Thanks

PS: if anyone has a imange for 18.03.36 I can do some report to double check and be sure of what I'm reporting on 18.04.20

My father has a cheap old Samsung 43" plasma tv that has a resolution of 1024x768, and Recalbox is perfectly fine on it.
It auto resized everything, and text n scrape data are in the exact same proportions as on my 46" 1080p tv, just not as sharp due to the lower resolution. .
I tried a few random emu's as well and all were fine.

@Dio good to hear :)

@Toni-Krüger that's just my personnal opinion, but i believe not. Such cable is made to "convert" usb to rs232, but you still need a driver on the OS side

...and thinking about this again... I'll just do the re-installation on a new SDcard, and keep the old one as is, for a plug and play backup solution. :)

have you tried advmame also with rpi2? it seems working fine to me
