The slot -2 flashcard uses two flashcarts and the -1 one. Also the -2 is the only one that can run GBA games. I think.
Close, but slot-2 just means that the flashcard goes in the GBA slot of the DS, it does not necessarily mean there are 2 devices. The only time you need a second piece of equipment with slot-2 flashcards is when you get a pass device to run NDS games/emus off of it from the GBA slot.
