@jamesfarnhamlong said in Retrotink U - Higher res ES and PSX games: The 450x270 looks best, but I was wondering if it was possible to run one @ 720x578 to improve the picture a little. I know the TV supports this as I have an old Apple TV that uses this revolution. How do I write the hdmi_timing to make this work? Is there a calculator or something I could use? Try this - http://eightvirtues.com/lakka/hat/RPi HDMI Timings Calculator and Core Docs.ods (courtesy of https://www.youtube.com/channel/UCtF_2HGXXPlUi1J0Euw1Qrw). Is it possible to adapt this to run at 2x resolution so I can use the enhanced graphics in psi-rearmed. Is there a way to have this only affect psx game launching? Or would it then throw out all the other systems? Is there much point? Maybe if you use the calculator linked above you can derive the correct HDMI timings to use. As for the effect on the other systems, you'll have to ask the author of those configs.

The config is the same, it does not matter if its pvm, monitor or consumer. You will possibly still need some tweaks , depending on your TV (to center the picture). That guide is quite old and so may be the timings he listed. I recommend looking at RGB-Pi or Retrotink configs on github, they're more up to date and work with Gert as well.

@Deityfierezy you are better for now with the 3+

@mukelarvin Well what i use in the video is the cheapest, but as of late I've been using a VGA to Component transcoder, theres a 15khz distro of retropie that someone made that works like a dream. they use some kinda data base for the customs timings, but I do like the RetroTink, its less of a mess when it comes to wires, but its about 90 bucks and needs some time to set up. So the HDMI to Component is kinda the poor mans way but it does work , it has its small problems , overall its a good starting point .. 12 bucks + 5 or so for the cables. for the vga666 i think i got mine on ebay for like 12 bucks and the transcoder is like 50 ish now..But its a mess of cables however with the right distro it's what works best for me, most of the arcade games run at the right rez. Retropie CRT Edition. keep an eye on this guy.He sales vga or scart to component transcoder's .. https://www.ebay.com/usr/linuxbot3000?_trksid=p2047675.l2559 As far as the Retrotink goes its just the cleanest after setup, less cables and less of a mess. I've trying to get that RGB-pi working with it .

If you have a bit of spare cash (~40EUR) get this: http://arcadeforge.net/Pi2Jamma-Pi2SCART/PI2SCART::264.html or this http://www.rgb-pi.com/ These are dedicated RGB solutions for SCART TVs. No lag and 1:1 amazing picture quality.

Thanks guys. I posted on Reddit and they suggested messing with the service menu. And I got it better by modifying the c-trap setting. https://www.reddit.com/r/crtgaming/comments/abt1fv/240p_composite_to_crt_tv_artifacts_blurry_text/

update: removed CRT theme renamed "HD" theme added grid view the CRT only theme is now unneeded so I removed it and instead renamed the "HD" one and added grid view.

@Sakitoshi thanks for your work, it was really good. I don't feel any difference being playing there or on a console. I'm having a hard time getting kodi to work on it, as I would like to watch my movies in a classic way. Do you know what I need to do to change this? I would also like to know if I can distribute a retropie for free on the Internet with its modifications applied? there are people who don't know how to make these changes and it would be a way to help. again THANK YOU SO MUCH!

bumping this one myself as I'm trying to do the exact same thing. i tried if, then, fi but i'm a total script noob so i'm sure my syntax is crap trying to achieve the following onstart if system = "system name" then do-a-thing fi anyone that can help?
