Well, yes and no, you do need a slot 1 for a minute, you can easily flash firmware to your ds so that it no longer requires slot 1 adapters at all, merely a game present for the sleep function. I personally recommend this route with a super card lite, for me it's the best of all worlds, the Slot 1 is overrated, and expensive to deal with, compatibility is *barely* better on a slot 1 adapter than on a super card, and the games that aren't compatible for the most part are crappy games. there is a tutorial available on you tube and via google to perform this. If you are uncomfortable with the whole idea then I would say go with both. It's all up to you and if you want to void your warranty or not.
