1) Click "All Files" under "Preview Not Available"
2) Download first file - it ends with .nds
I don't know what the other files are as I've never used this site before. The instructions are in case you're confused, too.
This is the file for the long awaited Death Note: Kira Game English patch rom. I don't use emulators on laptops or anything but instead use TWIlight++ on my 3ds to play roms like this and it worked fine on there so it should work on emulators. If there's any complaints or problems, I'll take it down so no one else downloads something unusable.
