There is no real way that the R4i can do what it does without having many of the people who have made the Nintendo DS console itself angry. I think that perhaps the Nintendo DSi needs the R4i. The r4i skins out there are some of the best though. With the R4i skins out there on the market right now, there is no way that the Nintendo DS can play emulators without the R4i and the Nintendo DSi can really use the support of emulators because it can be such a great console anyway. This is the best reason for it.
