I'm sorry if this question has been posted, because i try to search the forum but couldn't find any question similar to this, and I've read the FAQ but still not quite clear about it. My question are: 1. As the FAQ stated, in order to be able to play ROM on NDSL these are the things that required: Passcard, M3 (which is SD), and Superkey. 2. I know the purpose of Passcard, M3 but what about the Superkey??? 3. If I flash the firmware, then i will no longer need the passcard, do i still need the Superkey or i all i need is the M3 (SD) in order to be able to play both NDS and/or GBA ROM? 4. What sofware i would need to load ROM files from the computer to M3? Any input, advice would be appreciate. I'm new here and not really familiar with these thing. Again sorry for the noob questions. Thank you!
