I seem to be having problems periodicly w/my M3 DS Simply. What keeps happening is this: When I first put it in and turned it on it booted, but then it froze. After that, I put it in again and it just locked on the health screen, and I figured 3rd time's a charm, so I did it one more time, and all was fine and dandy. After that I was good to go for a while, but then I tried playing Megaman Battle Network 5, and it locked again on me, this time erasing the entire format on my microSD, so a reformat fixed it. Ever since then it occasionally locks on me, or the DS says there is no DS card inserted in slot 2. Is this a problem with my M3, or is this a universal quirkiness about m3's? I'm thinking of getting one for my sister, but I don't want her to go thru what I've been thru, and if it's the M3 I'd like to try to get modchipstore to replace, but I have exactly 8 days as of Sun March 11th to get an RMA. If it's just however how the m3 ds simply is, then I'll get her a lite perfect. Please let me know any of you out there that have a simply. Also, in case anyone says this, my microsd is supported and works well according to the m3wiki (4-5/5 on Castlevania PoR), and I've tried another (also supported) microsd w/the same problems. For what it's worth, I feel the card casing itself move (bow outward) as I put in the microsd. --EDIT-- I'm just trying to answer all the (sometimes quite likely) useless replies that will say "maybe you didn't..." or "perhaps you should..." by giving ALL this information. I also have reformatted the card in both Fat-16 and Fat-32 a couple times.
