Let me explain my case: I have two ds: One fat, other lite; both flashed, and two M3 simply Before, i had a G6 lite, and from my lite (with the G6 put in) to the fat (un-flashed), download play did not work...so i flashed my fat, and it worked...then, i flashed my lite too. So, when i was reading that download play did not work with all games, I was thinking that because my Dss were flashed, it will not be a problem... but yesterday, i tried, and it does not work with all he games I tried (mario kart, worms, bleach ds, lost magic) I do not understand, because with my G6 lite, because my Dss were flashed, it worked, so I thought that it would be the same with my M3 simply... So I wanted to know If it is a problem for you too, or if this problem exist only with flashed Ds ? and furthermore, could you tell me with which game are you sure that it works ? so i could test it... Thanks a lot !
