Btw I was assuming you were using the lr-fuse core. If using standalone fuse, then my advice won't help. Please let us know which emulator if you're not using the libretro core.

I had the same problem and the answer of @DanTarl in the post "https://retropie.org.uk/forum/topic/31488/solved-repeated-disconnect-of-zero-delay-usb-encoder-dragonrise/2?_=1640282263483" solve my problem

@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

Sorry to bring up an older thread, but much of the information here is highly inaccurate and is mostly due to people buying cheap flash drives and SD cards which are very hit-and-miss. I've tested in my Raspberry Pi 4b 4gb a Samsung EVO Select 64gb Micro SD, Sandisk Ultra 16gb Micro SD, and Kingston Canvas Go Plus 64gb Micro SD and they don't come anywhere near the performance of my Sandisk Extreme 3.0 16gb USB flash drive.

Here is the Samsung EVO 64gb Benchmarks: https://pibenchmarks.com/benchmark/51099
And here is the Sandisk Extreme 3.0 (for some reason it was identified improperly by the benchmark program. This doesn't change the performance numbers): https://pibenchmarks.com/benchmark/51100

Here is a link to the actual drive. https://www.amazon.com/SanDisk-Extreme-Flash-Drive-SDCZ80-016G-GAM46/dp/B00KT7DOR0

Booting from the Samsung Evo Select takes about 10 seconds longer than the Sandisk Extreme 3.0 usb stick.

That benchmark website pibenchmarks.com has tons of information on what drives are fast and what isn't. My USB 3.0 Samsung FIT drive is absolute hot garbage when running on a Pi 4. The fastest MicroSD cards do about 1700 points on the benchmark, There are USB sticks that score as high as 5,000 points. Then there are M.2 drives using USB 3 adapters which score over 10,000 points. Where USB Flash sticks and actual SSD/m.2 drives really excel is in the 4k random read/write tests which are the most important thing when it comes to performance.

@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 said in Retropie does not work on pi4 with xbox one wireless controller:

following all the videos and articles

That could be your problem right there. "All"? You don't need any certification to post a video online.
Without knowing what you did, how can anyone help?

Regardless, it's probably just a driver issue. You may have inadvertently deleted a file which one of the videos told you wasn't important, but actually was. Maybe you bumped the keyboard while editing a config file. I don't know.

@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 😟
