@classicgmr definitely improved

This usuall happens on the Pi4 when you're using a 4k resolution, for some reason the setup dialogs are not properly displayed.
Edit the config.txt file on your SD card (you can edit it from a PC) and add 2 lines at the end:

hdmi_max_pixel_freq:0=200000000 hdmi_max_pixel_freq:1=200000000

Try booting again your RetroPie system and see if you can open the setup script or raspi-config.

Thanks to both of you! I have something like 90% of my stuff copied over and now just have to go through to tweak some of my custom settings.

@kingcosmuder thats all i got running the command however i tired some dreamcast using redream and both games i tried, sonic adventure and marvel vs capcom 2 both ran 60 fps consistently so i believe its working now

@crush ok, thanks.

@mitu Thanks, the backup method worked. Strangely, my psx games were missing in the .img file, but otherwise it worked and it is easy to dump those with RetroArch anyway.

@omission229 No, sorry, otherwise I would have said so.

Oh, right. Sorry I forgot .-.

@quicksilver dont quote me on this, but yes i UPS will help level the spikes. a surge might, but i think the choke if there is one on a surge protector will not be that big compared to a UPS

@lolonois great stuff, thanks for sharing, I may give that try!

@rva-818x-laystar The only game i found running better than its DC counterpart is Marvel VS Capcom 2
the rest either runs the same or worse in the case of Dead Or Alive 2

@mitu said in Screen tearing in pi 4:

Try using fbi, it's an image viewer that works on the console also.

Thanks that looks promising. I’ll have to see if there’s a way to control which display it outputs to.

@mikeb hi there. How about you give us a little more info about your setup per this thread:

https://retropie.org.uk/forum/topic/3/read-this-first

We all have been there before with the frustration and trying to get things to work. I’m sure a different attitude will bring a better response from the community here.

@mitu thanks for the codeblocks sugerence i never ear about it.
In raspberry 3 retroflag cases if you use default script if you push power button it shutdown the pi and reset button reboot it.
With this code the power button, shutdown the pi saving changes and the reset button restart only emulationstation if you are in main menu, or exit game if you are in a game.

I checked pins and are the same but i dont know why in pi4 you push the button and the pi do nothing 😟

@planetdune Does the TV have a front RCA video input ? Try that and see if the signal works. Also, check to the /boot/config.txt has enable_tvout=1 added (should have been added by raspi-config).
