I was looking around this website and starting taking a look at the R4 DS, to play my back-ups. I understand how to work it and what it does, but I have a few questions to add. I was reading about fake R4 DS' and how a future update that will brick your DS if it is indeed fake. Where is the best place to buy an R4 DS knowing it will not be fake? I saw a few lists of retailers, but they looked a tad dated, im looking for a website that ships to United States. While having fast shipping and quality service. Some links would be greatly appreciated. And does using the R4 DS void your warranty? I was looking around and saw some people saying that it did not, and some saying that it did. The warranty does not matter to me, I just want some clarification. Also, from what I was reading from some of the dated posts, R4 DS was the best thing for back-ups, but not homebrews. Is there a newer better product that is better than the R4 DS? Or is R4 DS the best thing for playing back-ups. Any recommendations to a better product will also be appreciated. I'm just looking for the best product for the best value. Thanks.
