None ROM is working

[phsgbr]

Hello Friends! I have a Raspberry pi 3, with Recalbox 4.0.0 beta2 instaled, usinga a x360 controller. All the resources are working, but when i try to start any ROM, from any emulator, the recalbox shows a black screen with the logo and the version on bottom. After this the system goes back to the rom list. The faq says to install BIOS, i did, but without changes. I can not play no one game (i tried SNES, Genesis, GBA, N64). Help me, please!

What's your monitor ? does it support 720p ?

Yeah, I did test on my 2 tvs. Both are 1080p, but supports 720p too.
