Main menu on DS gone

I am probably in the wrong section but my son's card kept saying something about the data and wouldn't work. So I transferred all the games onto my computer, formatted the card and transferred everything back. However I must have forgot to transfer the main menu cause nothing happens now. It just says MENU? How do I fix this stupid mistake. Thanks.

What kind of card are you using?

www.linfoxdomain.com/dsDownload the Menu (Firmware) files for your card.

you are missing the file called 'ds menu' if its a proper genuine r4 then wood is the best firmware or ys menu .
