Through the years I have owned quite a lot of consoles, and games for those consoles. Most of them however I have either lost, resold, or given away. Would it be illegal to download the ISO's/ROM's or the BIOS of those games/consoles I am certain that I owned at one point in time? Seeing as it is already legal to make a backup of the games, as well as to copy the BIOS, and since I owned everything at one point in time, wouldn't it be legal?
