I tried that trick (read it on another forum) but it doesn't work for me. When I run them from BigBlueMenu, I get the black error screen (an error has occured, etc...)
Mmmmm, are you sure that the games you are trying to run doesn't require a higher FW version? check 3ds.essh.co . or try with an old jpn game like the new super mario bros 2 for example.
