As the pioneer of the Nintendo 3DS hakcing devices, sky3ds flashcart allows users to run 3ds backups directly on the latest 9.2.0-20 J/E/U n3ds console, no firmware limitation anymore, no need to use two cards. If you have a 2DS, DSi, DS console, or if you just want to play ds backups on your N3DS, you can go ahead and buy an R4i gold card directly. If you have a lower version N3DS and you want to play 3ds games, gateway 3ds and mt-card will be a good choice for you, these cards allow you to play all the 3ds games to date, but they only work on 3ds firmware beyond 4.5.If your n3ds is a brand new one and has the latest 9.2.0-20 firmware, you will need the sky3ds flashcart to play 3ds backups. As I mentioned before, you can run 3ds backups on the latest firmware n3ds console directly. However it has the 10 games max limitation at the moment, it means user can play 10 games at last with each sky3ds flashcart. Today, many users confirmed that their sky 3ds cards can run more than 10 games.
