Please Help!! DS trouble

[dominorocks]

Hello was wondering if anybody could help me. After having spent hours on the computer I still cant find a solution. I have sucesfully downloaded some games to my DS a while back. Recently when uploading games I have been unable to play them. I get an error message asking me to reinsert the card and start again. Does anyone know how to fix this. I have a feeling its something to do with the arm7 fix thing - which I have downloaded but what do I do with it once it has been unzipped? Do I need anything else as well? I have downloaded the new kernel so its not that. Please help - I'm sick of searching on the net. I need it put simply as I'm no expert. Thanks in advance for any sort of help xx

Also can I add onto this - where does everyone get their games from these days??? thanks

Hi
are you using nds files with the name of the games ending in .NDS IS SO ALL OK

One of your games on the card could be a bad one

Try formatting your mem card put on the software and your games on one by one and try them as you put them on.

Hi thanks for your message. Yes all the files end with .nds it seems to be any game that I have downloaded over the last couple of months. Lots of people are mentioning the arm7 fix. Do you think this could work and if so how do I do it? I have looked at other threads but it doesn't state clearly exactly what to do once you have downloaded it. Please help!!!

Thanks in advance
