I don't think super resolutions are going to work with a HDMI converter (on a Pi4). Those worked on the Pi3 with older versions of Lakka/RP. The people in this thread who have had success doing what you are trying to do are using mode 1, 8, which is 720x240, 4:3.Guile wrote:I changed it to RGUI and set the resolution to 2048x240 but I got the same result. It's just a bunch of horizontal lines with the lakka flower broken up and looking like it resets and tries to boot. I also tried this config https://www.retrorgb.com/rpi240p.html but again same result.vol.2 wrote:
You have to set Lakka to RGUI and change the resolution in video settings before you hook it up to the CRT.
Maybe my converter isn't compatible or something else is going on.
Also, sometimes Lakka gets "confused" and the config file gets corrupted. You may have to periodically wipe the image and start over as you switch settings around. Once you find a setting that works, it should be fairly stable.
