Set your default video resolution at 720x576i or 720x480i and switch to 240p when running a game, using the Runcommand onstart script - https://retropie.org.uk/docs/Runcommand/#runcommand-onstart-and-runcommand-onend-scripts.

@mitu
I changed device to pcm and volume to 50.00000 no effect.

@mitu Yes, it is!

So I thought I had better post to say that I solved my own problem. I had to get sync from SCART pin 19 on the Pi2SCART's female connector, not pin 20. I did not know about male SCART leads swapping pins 19 and 20. I hope this post might help somebody else out one day.

@DJMoss Adding active cooling eliminated the slowdowns I encountered while running some MAME or NeoGeo games.

@djmoss - I have the exact same setup as you (Pi4, pi2scart, mx7000). I have a couple of problems with overscan. Did you fix this through the config?
If too much OT perhaps we can take it in a pm?

Thanks! 😊

@mitu
That fixed my problem - thanks for your help.

I've just made a donation to Retropie because it's my favourite community project and your help, although a bit tart, was faster and more useful than any paid support I've ever received.

I see! The screenshots from your link really do show the difference. Thank you!

@r_g_b_life said in Raspberry pi 3 b+ and pi2scart problem:

Sudo bash ./set_video.sh They won't turn on. I uploaded the scripts to a pendrive. Raspberry sees these files from position F4 but these commands cannot be turned on.

I'm not familiar with those scripts, don't they have any documentation attached ? Try copying them first locally, on the SD card, instead of trying to execute them from the USB drive. After you copy them, make sure they're executable - run chmod +x <file_name> beforehand.

@grant2258 Top post explains it a bit more. I can already get the game flipped on a CRT TV. I can't get Emulation Station flipped too. Flipped to work if viewed in a mirror.

@Efriim It is possible if you feed it some outlandish timings. I am not saying the ones you have posted will do that, they may well work OK, but not knowing the source and what they were intended for it's hard to say. I'm talking about the hdmi_timings ones, these can be dangerous. The config.txt is good, but I would skip the ones from your post starting with hdmi_cvt.

I'm bit busy now but will post my confirmed-working settings (for a CRT TV though) later. In any case OP should try the arcade forge image first, even if just to copy the configs from it to the official Retropie.

EDIT: my old config.tx. You can also try the "AF" and "mohl" settings (just make sure to remove #AF for example)

This should give you a stable picture, I have used these settings on many CRT TV sets, they should work on a monitor too I think (or at least won't damage it).
problem is, this will only work for few emus in 1:1 scale, since they often used different resolutions. To handle this you need to use the high-res trick (read the thread I linked to)

For that you need to change the runcommand and then also adjust the settings in retroarch.cfg (custome aspect ratio and resolutions, or use integer ON/Off option). Unfortunately I'm not near my SCART TV sets and can't remember all these settings exactly so can't help you here. You either use the Arcade Forge image, figure it out from the resources here or post on reddit in /r crtgaming sub.

My runcommand-onstart

fbset -depth 8 && fbset -depth 16 -xres 1920 -yres 240

My runcommand-onend

fbset -depth 8 && fbset -depth 16 -xres 320 -yres 240

@DaveGeorge
I am facing the same issues.

Can you please share/confirm the final settings that worked?

Thanks a lot for your support

Just some follow up info. When I put Aspect Ratio to 4:3 the screen is vertically stretched with massive black borders on either side which take up most of the screen.

I don’t know the exact pi out of the pi2scart, but you can find the used pins of the PowerBlock at https://blog.petrockblock.com/powerblock-raspberry-pi-power-switch/:

S1: pin 12
S2: pin 11

If this does not collide with the pi2scart, it should work.

I also have the pi2scart ouputting on a 28 inch consumer crt from philips and dont have those "problems". I cant even take photos of my scanlines becaues they are so subtile. Would like them a bit more beefy to be honest but its not that easy to get a pro crt here sadly.

thank you

@yuke not that i know of.

@RetroCrtGames Can you help me how to enable these commands? Sudo chmod + x set_video.sh
Sudo bash ./set_video.sh I am reaching the / root / video folder and I can't turn them on 😠😠
