Problem Rockboy Sansa Clip+

[DrMeow]

I have a problem with Rockboy on my Sansa Clip+.

In fact, my GB & GBC games works perfectly on my computer, but aren't detected when I start my mp3 ( when I search them with my mp3 in the folder they are in, my mp3 doesn't detect them )

Any idea on how to solve my problem ?  

EDIT : I found my problem's solution : in fact, in Settings/General Settings/File View/Show Files, I clicked accidentaly on "Music". That's why only MUSIC was displayed, and not Games.
