Hey. I got my R4 a while back, and played DS games on it, fine. (I assumed it was the legit one.) Some games didn't work (white screen/freezing, etc.), but I was to young to understand why and to lazy to bother finding out. Now that I'm playing my DS again, I've been trying to install Wood R4 (R4 Wood?) on my DSL, which works fine, but when trying to boot roms, I get a WSoD. Some poking around the cyberspace informed me that R4 clones SEEM to work with wood, but crash when doing anything other then running through the GUI. So here I am, asking if my R4 is a clone. ^ That's the cart I have, except; between the big "R4" and the "Revolution for DS", it says "Upgrade" in the same shiny font/text as the rest of it. (Not Upgrade III, just Upgrade) Another thing: whilst looking through youtube unboxing vids, I realized that most of those came with USB adapters, whereas mine came with an adapter chip. (?) Edit: Another difference; the text on the image is white, whereas the text on my flashcart is foil/holo silver.
