EZ-Flash has disclosed the availability and price in ChinaYeah, for $13, it's gonna become the baseline standard for flash carts and clones I feel like (when it eventually gets cloned too).
It's just hard to find a reliable DS flash cart that runs WOODR4 right now, so this is a very promising option for me. Most of them come with some modified Ysmenu, and I can't stand Ysmenu.
