I've read up all the tutorials here, and I think I've learned more from all you helpful folks than I have anywhere else. I see that M3 has received a lot of praise and even online they look good. Mind you, I still have a few questions... I'm looking to play both GBA and NDS using MicroSD on my DS Lite (as well as emulate NES, SNES and Genesis if possible). So, my understanding is that I'll be needing a boot chip (Passcard3 or M3 DS Simply) for my DS slot, and a storage cart for my GBA slot: hands down, no matter what combination, this seems to be an M3 Lite Perfect. The tutorial by XBusterZ mentions a setup where I can get the M3 DS Simply AND the M3 Lite Perfect. Isn't this a bit of a waste, given that both will have MicroSD and the Passcard3 + M3 Lite Perfect can both boot DS games? Why would I want to use an M3 DS Simply and an M3 Lite Perfect? Which combination has the best UI? Passcard3 + M3 Lite Perfect or M3 DS Simply + M3 Lite Perfect? What about other DS boot cards, will they work with the M3 Lite Perfect? I'm a little hazy on the interaction between the DS & GBA components involved still. One of the things the tutorials here mentioned is that you have to patch NDS ROMs before you upload them to your micro SD? Is this still required in current versions, or have things with M3 progressed to the point where my NDS ROMs will work no matter what state they're in? This is probably the biggest thing holding me back right now as I'm certain if I get a M3 Lite Perfect and a Passcard3, I'll be off to the races. Despite that, I still want to get the best looking and most simple to use combination possible.
