It seems that PPSE-DS doesn't have many users, but frankly, its amazing. Yes its features are limited (You can't create a pokemon from scratch, or change natures yet) but it is a fantastic idea. I barely have time to edit my pokes on the computer, so being able to do it on the go on my ds is great. I hope it continues to be supoorted, and more features added, and I really like the concept. Thank You Project Pokemon.
Also, you can add "M3 DS Real" to the Compatible Flashcarts list - it works on mine!
