Just got in my m3i zero, and its not working. Its one of the GMP-Z003 ones. I follow the tutorial on how to set it up correctly, and i hadn't run into any problems. The game came up as finding nemo which i was told is correct. Now when i try to start it up it says "No system file found ! Put system file in" Ive tried it on both ds's i own (both ds lites) and its the same thing. i tried System V4.9a X (Europe/USA/Asia) (26-1-2011) M3i Zero Core data file V1.7.2 (4-3-2011) I should note I purchased the m3i zero after my r4 sdhc happybox started failing on me. It worked fine at first, then it kept giving me a white screen when i tried booting, thinking it was broken i went for the m3. The only thing that could make sense to me, is that theres a problem with the micro sd card. Ive been using the same card in the m3 as the one i used in the r4 which failed on me. But i dont see how there could be anything wrong with the sd card. Ive used it to transfer roms from one computer to the other and i also used it to flash the m3. Can anyone tell me what the problem might be? Is it possible that my sd card is broken and my r4 never broke down to begin with? Thanks!
