@alexander-tolstykh Just to understand better:
"I change usb sticks with roms and everything start working again."?
Do you have Recalbox installed on the SD card, and do you have ROMs on a USB stick?
And now you're trying to run straight from the SD card and you're in trouble, is that it?
Or were you running from a USB stick and now trying to run the ROMs on another USB stick?
Because it looks like you were running from the SD card, removed all the ROMs from the SD card and played on the pendrive, but did not mention that it entered the Emulationstation settings and changed from "internal storage" to "external storage", so the recalbox is locating the ROMs, is not it right?
You did not mention anything about it in the topic, only said that nothing is working, we need as much information as possible to help you, please explain what you did from the start, how it was running, what you did before it stopped working, etc.
What's your version of Recalbox, and, did you created your own image, or did you download a image ever made, or did you buy it?
