black screen on the Atari 7800. sound exits but nothing appears on the screen
In: \RECALBOX\share\system\recalbox.conf
Change this line:
global.videomode=CEA 4 HDMI to global.videomode=default
it's really a hell this black screen ;-( i've still work to fix it in all cases.
nadenislamarre is the same problem of the retropie? something with framebuffer, i think they solved with a patch in sdl
