Well, I ordered from Winsunx. They say in their item description that it will work with all versions of EZ4, m3, supercard, etc. So I'm gonna trust them. If not, then I'll just sell it on craigslist or Ebay. I have a flashed DS Lite, but I was thinking about getting a black one. I was getting a EZ4 deluxe from winsunx and I decided to pick up a flashcart for only $15.70 extra.
