@gnubit Thanks for the tutorial, but on my NUC7 i had to insert a "sleep 1" before the "xrandr -s 1920x1080" line to make it working.

Without "sleep" it fully started (you could hear the music and ssh access was possible) and the tv displayed the correct resolution but the screen was black.

@ratte dreamcast isn’t available on anything lower than rpi3, so these are pointless:

gpu_mem_256=128
gpu_mem_512=128

Regarding
gpu_mem_1024=128
And the pi3... as mention before, the WSOD can (still) be a problem, but also some arcade games woul not even start with that setting or would not have sound either.

@robertobox no abras dos hilos preguntando lo mismo.
