Theme for super CRT resolutions 1920 x 240

NikooZ

@M3th0D Yes my VGA adapter for GPIO works with vga666 overlay

@NikooZ Retrotink is a very similar setup to GPIO, maybe overlay is different but we use the same runcommands. It should work for you, are you sure you did everything right?

I use Pi2SCART (GPIO, 666 overlay) and this is my runcommand-onstart:

#vcgencmd hdmi_timings 1920 1 24 192 184 240 1 4 5 14 0 0 0 60.0 0 36609600 1
tvservice -e "DMT 87"
fbset -depth 32 && fbset -depth 32 -xres 320 -yres 256

You can replace the values after hdmi_timings with your own hi-res ones. Just make sure you get rid of them in config.txt (put hdmi_timings 320 1 23 25 39 240 1 4 3 15 0 0 0 60 0 6400000 1 instead, they work on my generic Trinitron)

and runcommand-onend:

vcgencmd hdmi_timings 320 1 23 25 39 240 1 4 3 15 0 0 0 60 0 6400000 1
tvservice -e "DMT 87"
fbset -depth 8 && fbset -depth 16 -xres 320 -yres 240

Alternatively you can try to use this ready made images (download vga666 version): https://www.elotrolado.net/hilo_retropie-crt-edition-raspberry-pi-2b-3b-3b-tv-15khz-vga666-pi2scart-rgb-pi_2328132

@M3th0D there was a thread about using this adapter and settings for it recently, have a look around

@youxia I've had a good look around the forum but can't find what I'm looking for. It's ok if i use 480i but i have a decent 240p theme. I am having to play at 320x240 atm :/

NikooZ

@youxia Thank you ! I will try it !

@youxia That didn't work. The error log show me the same error as my previous tries :

@NikooZ what PI model do you have ?

NikooZ

@mitu Pi4

mitu

@NikooZ tvservice for resolution switching is not recommended anymore for the Pi4, due to the change in the GPU driver stack. Most likely any setups relying on it for dynamic resolution switching will encounter problems.

NikooZ

@mitu OK thanks. We have to wait for a solution, then !

Meanwhile, I can test these previous settings on a pi3b+, this will work ?

Yes, they should work.

@M3th0D I don't really know much about this method (pun not intended :), you can have a look at these two threads, maybe you can salvage something from there. shmups.System11 is always a good place to ask about such stuff anyway:

M3th0D

I think the only way is to have something like:

CEA for emulationstation and DMT for retroarch. I can't figure out any other way :/

I don't think anyone really replied as to the best theme for this type of setup? What themes that work well?
