NES Roms for NesterDS?

i tried downloading Castlevania NES for Nesterds on my ttds card, but it won’t load when i select it. i converted the file and everything but it still only loads halfway then stops.

http://www.romnation.net/srv/roms/nes/c.html is the site i got it from. do i have to download all links relating to Castlevania and put those NES files onto my card in order to play them?

P.S i downloaded Ninja Gaiden from romulation.net (the download for Castlevania has been taken off) and it came with about 20 other NES files and when i put them all onto my ttds card + the converted .nds file, it worked so is that what i have to do for Castlevania as well?
