R4 DS GBAtemp Review

Excerpt: "The R4 DS is a slot 1 DS flash kit designed to play ROMs. I may be stating the obvious here, but the point is; that's what it's meant to do, and it does it very well. From our extensive testing, so far we can confirm that the R4 DS is 100% compatible and doesn't suffer any slow downs in game."
