I would make a backup of the SD card and then I'll
formate the SD card. And then put your firmwire and
games back ans see of your problems are solved

OK, being a novice at this, do i need anything special or is it just a simple as that?cheers

most of the time problems like are easy to solveyou just need to know what to do when yous R4 or EDGE
won't workjust do as I said before backup your SD card and formate it
then put back your firmwire and your games
and see of it worksDo you still have a problem with your SD may have dead on you,
so then you will have to buy a new SD card.I'll hope this will help you if not please let me know and I'll
try to solve your problem instead
