I've been out of "the scene" for many years now, but back in the day, I had a Flash Cart[0][1] so that I could have all (literally all...) the Nintendo DS games at hand. I was a naughty naughty pirate.

The flash cart also added some really neat features that were missing, such as: the ability to take screenshots, ability to save and restore a game at any point, ability to load cheats like infinite ammo and such.

Nintendo was/is at war with cart users and any update to a DS with a flash cart stood a good chance of either killing the flash cart or rendering it inoperable until a new firmware was released for the flash cart (which may never happen). There's a long and great history here. And if you want to know more, the GBATemp wiki[3] is a great starting point.
