(Warning, another newbie that doesn't know what she is doing.... be gentle ) Okay, just got M3 Lite and Passcard 3 today. Downloaded the latest game manager from the site and flashed it in GBA mode and everything went well as far as I could tell. So I put New Super Mario Bros DS on the card. I start up the DS Lite and select Passcard3 (thats how you play .nds games, right?). It goes to the splash screen and then it goes to the black warning screen and it just stops on that screen. I left it for a while and no change.... I don't think its the M3 because I put a GBA game (Mario Kart) on my microsd card (which is a Sandisk 512mb btw) and that works fine. I saw some people suggesting something about cleaning the contacts and realigning the passcard... if you think thats the problem can someone tell me what post to look at for more info? I hope its nothing serious If anyone could help me I'd immensely appreciate it. I know you guys get a lot of people like me but I couldn't find any other posts that had the same problem as me. edit: I just thought to mention this too. I did try to play a regular NDS cart (Kirby Canvas Curse) after this to make sure there was nothing wrong with the slot and it played fine.
