DS Games unshown on R4

I have an 8gb micro with my R4 SDHC and it only shows 45 games when I turn on my DS through the directory. When I open it in my PC it shows all 60. Why can't I get to see thema ll on the DS? Also how many games should I be able to get on an 8GB card?

try putting them in different folders, there is a limit to how many files it can show in one folder.

My 4gb can hold 65 games so...

Of course, this is an issue with freading all of them at the same directory in FAT.
