M3 DS REAL CRASHING !

Hi
I have recently upgraded from M3 simply to DS REAL (san disk sdhc 4gb card) and had problems at random when loading the game the list of current installed games/roms, the screen would crash and lockup. I tried two other identical adaptors and cards with the same result and to get them to work again the cards had to be re formated and the system software and games reloaded.
After trial and error I changed the NDS folder name to lower case (nds) and made the folder read only and archive and the problem seem to have been solved, has anybody had any problems like this ?
hope this is useful to you guys.

 

yes im downloading the games clicking on the games when my ds is on and there loading and the screen goes white or black?? is this what kept happening to you??

Please helllpppp me what am i surposed to do??

 

Try backing up, reformat, and reinstall the latest firmware.
