WarioWare D.I.Y. videos show you how to ... D.I.Y.
You'll notice that the guy in the videos is using a DSi XL — we can tell you that, after seeing the hardware running D.I.Y. in person, the hefty handheld's humongous screens really are great for editing sprites and other details, as is the pen-sized stylus. Either that, or our eyesight really is getting worse.
