Thank you very much, this solved my problem! I was changing things hundreds of times with no avail, luckily some laser-precise google search managed to find this blesses thread 😛
@hitmaker Your SD card is probably corrupted.
You can try to recover it with Windows, but, it may be necessary to reinstall the system and, perhaps this will not even solve ...
The recommended is to use a small SD card for the system, and put the ROMS, BIOS and other things in external storage.
@hitmaker If you use the joysticks on PS4, you need to reset them first. Another possible solution in the emulationstation control setting is to "forget" the already paired controls (I can not remember the right term in English now, and the translator may affect the translation).
