Hello,
I am using the latest batocera with a small pc i built with spare parts. It’s a ryzen 1700 and radeon r5 230 gpu. My crt is a bvm 20f1e. This gpu seems great with the vga out, it support low pixel clock and i flash it with atom15 bios. In windows and crt emudriver there is an option to enable csync, i don’t try it myself but it is suppose to work fine. There is an option with atom15 to enable csync.
I didn’t found much info how to enable it on linux. It would be great in my setup to have it enable, i build two sync combiner (the retrorgb schematic) but i need them for something else, and i am lazy to build a third, especially as the hardware is suppose to support it.
Thank you
