Thank you!
Folder browser, I can definitely do that in future releases.
But for the playback while lid is closed, unfortunately I'm not able to. It's a 3DS limitation. Apparently, when the lid is closed, it cuts audio to the speakers. Believe me...
It's a shame the 3DS doesn't have this feature, but thank you again, your player is very good and of good quality.
You could add two taps of the L and R buttons to go to the next track; one tap when it's in your pocket causes it to skip...
It runs without graphical glitches, but the speed only stays close to 60fps when skipping 4 frames; skipping 1 frame results in around 45fps, though it is playable when skipping 3 frames. Thanks.
