Have just published this - https://retropie.org.uk/2019/07/composite-out-broken-on-retropie-4-5/

it depends on the shaders you are using now. for example, assuming you use 240p with your new CRT, a scanline shader would be pointless because a) 240p already shows scanlines on a CRT and b) 240p is not enough vertical resolution to allow fake scanlines to be rendered. shaders that adjust the colour or fidelity of the image may or may not be useful or provide the desired effect, depending on what they are doing and how you are connected to your CRT.

@mitu Saw some feedback on it in my searches..Thanks for confirming...

@mcorcoran I wonder if it has something to do with GFE version because you're having to use "-unsupported". Do you have the newest version of the GeForce Experience installed on your Windows PC? Also, you might have just typed it wrong in the post but "-localaudio" is just one word without spaces. I remember one time I was having trouble with resolutions and I discovered I was spelling "width" wrong. Another thing you can try is putting the "-width 720 -height 480" before the "-unsupported" in that command. If you could get it working without "-unsupported" by updating GFE, that would probably be better. Last, you might also experiment with the refresh rates by adding either "-fps 60" or "-fps 30". What refresh rate is your Windows PC when you manually set it to 720x480? That would be the refresh rate you should try first.

I went with this one , had free shipping. Will post when tried out.

Yes, it might be possible. You'll need to modify the autostart script in /opt/retropie/configs/all/autostart.sh and start either Emulationstation or the desktop - depending on your current TV connection. There's a way to detect which output is connected (see this topic), so you can use something like this: if (/usr/bin/tvservice -s | /bin/egrep 'HDMI|DVI') ; then # Start the desktop xinit else # Start Emulationstation emulationstation fi

Adding this line to Mednafen VB.cfg: video_refresh_rate = “50.0” Fixes the timing issue, hope this post helps anyone with the same issue. Runs great now! ( btw, definitely lower the audio_out_rate to around 33200 or something like that, and sample fidelity to lower and add some audio time skew, no framedrops or sound skips now that I could notice even when playing in 3d )

Very impressive

@M3th0D I was getting 15khz out of HDMI like you but i went into a hdmi to component converter, using retropie.. I came a cross this post when i was trying to work things out, and seen the runcommand , I used it but in a different way,,I got emulation station running in 480i, and retroarch running in 1600x240.. and it switches back to 480i when exiting games. https://retropie.org.uk/forum/topic/22467/hdmi-to-component-crt-help-runcommand/10 just wanted to pass on the info.

@future-child Thank you. Some of the links are for eMac, which I didn’t even know existed. Not as cool looking as the G3 iMac but fairly solid design as well. I found the last link myself as well and that one made me hesitate with even starting to plan this project as it seemed like a huge pain and was not resolved in that thread.

@TreyM, Any progress on your reshade version? I didn't see it on github. I've been working on a standalone CRT shader, but would love to incorporate the day/night cycle and overlay swapping.

@mitu jajaja!! Yeah, between a messed up menu and non centered menu I prefer the not centered one that is redeable. Thanks. I will edit the autostart file and see what happens when I connect it back to an HD screen (so I can prevent any surprises if I ever take the Pi to a friends house)

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.

@mhughson said in Stuck at bad resolution: Thanks for the help! I didn't do anything, but glad you got it sorted out !

@240pnoob said in 240p Over Composite to CRT Problems: any easy guides on how to do this? Keep in mind I have only had a raspi for about 24 hours, with 20 of them being me fighting it. You really should read on about the Raspberry Pi and RetroPie in general before trying to customize your installation. Themes can be installed from the RetroPie setup script - https://retropie.org.uk/docs/Themes/.

@polish-potato is configs/atari2600/config_crt/Stella/ not configs/atari2600/config_crt/Stella/folder the name of the file you need to create is exactly the same as the name of the rom. in the example below my warlords rom is named Warlords (1981) (Atari).a26, so the name of the config has to be Warlords (1981) (Atari).cfg lastly, retroarch_crt.cfg is not the active configuration, is only the preset that is applied when you use the runcommand > user menu scripts. the active config is always retroarch.cfg.

@jamesrives said in 4:3 themes?: SNES mini theme The SNES mini theme seems to support a few 4:3 resolutions, look in the config.xml file inside the theme folder.

@mitu Yes i edited the XML file. The default was 1920x1080 and i changed it to 640x480, which of course is 4:3.
