@petro Sorry to insist, but you have not made it clear whether you checked the BIOS version in Recalbox MANAGER, or how you did it. Also, what is your version of Recalbox? What is your hardware? Did you build your Recalbox yourself, or did you download a ready-made image from the internet? You are right: the link was just for you to know which BIOS version to use, BIOS and ROMS are copyrighted, so its distribution is illegal, and against the forum rules.
