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:
@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
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.
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.
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 😟
