TTDS Freezing

I bought my daughter a Nintendo DS and after much review reading I bought her a TTDS chip.  In the begining it was really good as I only had a few games on there, but once I loaded the 2GB Micro SD card with other games I instantly ran into problems.  Launching any game would cause the DS to freeze completely.  Other times the game would start to load and then freeze.  A quick Google later and the fix was to format the Micro SD card.  I formated, copied the games back and all was good.

Last week I upgraded the 2GB Micro SD card to a larger 4GB Micro SD card.  Along with the card upgrade I also upgraded the TTDS menu software.  This time I formatted the card straight off, copied all the files on the card and the same freezing that I experience before came back.  After Googling again I found that I had to put all of the games in a sub folder instead of the card root.

I created a folder called Games, put all the games and save game files in it and it worked without any issue.

The root on my Micro SD card now looks like this:
