Dsi is a last generation of the ds systems. They reduced the size and removed the GBA game slot. It has the capability of connecting to the internet, record sounds, take pictures, and downloading games from the dsi shop. The XL is the type in which they expanded the size of the system to have larger displays

It takes an SDHC card. However, you only need one if you are going to download games, music, pictures. So, if you are using this solely to play DS games you will not need a SDHC card. Hope this helps.

No. Nintendo has a strict license agreement. If the game was bought on the system, and you bought the system with the games, yes they will work, but you can't just put games on an SD card and play them.
