M3 Real Rumble pack problem

For some reason I've been trying to play games that use the rumble pack and I'm having some major issues. Unfortunately it keeps making a loud sound and it isn't vibrating properly. I tried turning off the system and re inserting the card but I still have issues. Is there a reason why its not working properly? Like did I have to download anything?Second question:Also ocassionally like in FF3 I quicksave and for some reason when I restart my NDS it says slot 2 and then it stays at a white screen when I'm trying to play a slot 1 game even though I don't have a slot 2 card. Its weird and its bothersome.Thanks ahead of time!

if changing the batteries doesnt help the rumble, then its likely broken.

Really? Aww..man I bought the m3 real like two weeks ago and it finally arrived :(

Wait so I need to get a whole new battery? Damn, I'm too poor for that.

Most people find that every single rumble cart is too loud or doesn't work properly. The rumble has a vibrator in it with a battery, so probably, although I don't think it's a good idea for you to open it yourself, send it back in or something.

Ok then thanks.
