Hi everyone, I'm new and need help :)

Hi everyone, I just bought my son a nintendo 3sd xl for his birthday. I bout the r4i 3ds cartridge and have downloaded the firmware for it. The thing is every site hat i have come across to download the ds roms brings me to another site which i have to pay to download or download software like ilivid instead of the file I want. Can someone please direct me to somewhere so I can download the games directly without be redirected?

Thanks

Paula
