jorlain, you have very common problem, and it's fixable with putting a paper in front of the M3 cart when inserting in NDS, because some newer NDSs have problem with getting connection between system and metal pins on the cart..
I had the same problem with my Crimson/Black and M3 Real...(and M3 Real works perfectly normal with my Polar White NDS, but doesn't work with Crimson), so just place a paper in the way that it pushes pins and makes connection in NDS..
You'll have to move it a bit around, to find a proper way that works for you, but it should fix your problem!! wink.gif
QUOTEWell, I had lots of problem with getting it to work properly too..
Try this, it worked for me..I hope you'll understand what am I trying to say..
Use ordinary, plain paper, but bend, so you get two layers..Then, cut it in the size of the pins that make connection, stick the paper on the other side of the cart, so that pins are pushed towards NDS connection, but try to keep paper under the chip protruding (it's been said that the chip is actually the main source of the problem, it sticks out and creates small space in between pins and NDS)...Try several times setting the paper like that, and if it doesn't work, you'll need a thicker paper, so use part of the corn flakes box, just cut out the right dimension..
Remember, try to stick piece of paper in a way, that it doesn't go over protruding chip!
Trust me, it'll probably work after some time, but you'll have to try hard!
Good luck!
