Hello

i want try "RGB-PI OS" with the Arpicade.
but i become only a black Screen on the CRT.
what must i change in the config.txt.
I hope anyone can help me.

hdmi_timings=320 1 10 30 40 240 1 3 4 6 0 0 0 60 0 6400000 1

## RGB-Pi Custom Configuration
## IMPORTANT! hdmi_timings must be always in the first line
## hdmi_timings=<h_active_pixels> <h_sync_polarity <h_front_porch> <h_sync_pulse> <h_back_porch> <v_active_lines> <v_sync_polarity> <v_front_porch> <v_sync_pulse> <v_back_porch> <v_sync_offset_a> <v_sync_offset_b> <pixel_rep> <frame_rate> <interlaced> <pixel_freq> <aspect_ratio>
## Usable Pixel clock are : 4800000 - 6400000 - 9600000 - 19200000 and anything over 38400000

Not sure exactly what changes would be required. Not even sure what RPi you are using...

As far as I'm aware RGB-pi uses the GPIO for video, RaspberryJAMMA/ARpiCADE uses the GPIO for inputs. There's probably some other differences too but I'm not sure, I've never had a reason to use RGB-Pi OS (or their hardware) as my stuff already existed.
