What console games can I play on my DS

I'm new to all this and have managed to easily download DS games onto my DS real, however, there are lots of older games like those on the Game Gear for example, which I would love to play again, but, can I do this on my DS using the DS real and if so how do I do this?

Some older handhelds can be played on the DS by putting an emulator on your flashcart.
