This might be a long one so bear with me. I've had my DS for nearly 2 years now but hardly played it and recently decided to get TT card etc... I followed all the instructions given by the Saint (Thanks, your a hunny x) and got the games loaded. DS turns on, shows the games that are on it, even starts them up then for no reason at all it either a) Says the card has been taken out and to switch it off, put it back etc.. but i hadn't moved it at all. B) freezes in random placed in some games but plays others. The most annoying yet confusing part is that I also did the same for my Daughters and hers works fine. I've used her TT card with her chip and it freezes, I've used her TT and my chip, my TT and her chip etc... I've even wiped the micro SD, formatted and loaded them on again but nothing works.... I'm going to cry!
I spent hours on Saturday trying to do it and when I finally triumphed, It won't work. (Not to mention a 10 year old keep telling me that hers works fine...GGGRRRRRRRR
