Interface Overview

Tunez3DS uses both screens of the 3DS:

• Top screen — Now Playing view showing album art, track title, artist, progress bar, and playback status
• Bottom screen — File browser for navigating folders and selecting tracks

Controls

Button	Action
D-Pad Up / Down	Navigate the file list
A	Open a folder / Play a track
X	Pause / Resume playback
Y	Stop playback
B	Go up one folder
START	Quit Tunez3DS

File Browser

The bottom screen shows the contents of your current directory, starting at sdmc:/Music. Folders are shown in blue with a / prefix. Use D-Pad Up/Down to navigate and A to open a folder or play a track.

Long filenames scroll automatically after a short pause when selected.

A scrollbar appears on the right edge when there are more entries than fit on screen.

Pressing B to leave a folder will automatically re-select that folder when you return to the parent directory.

Now Playing Screen

When a track is playing, the top screen displays:

• Album art — extracted from the MP3's embedded ID3 tags (JPEG or PNG). A placeholder box is shown if no art is found.
• Track title — from the ID3 TIT2 tag, falling back to the filename if no tag is present
• Artist — from the ID3 TPE1 tag
• Progress bar — shows playback position with current and total time (e.g. 1:23 / 3:45)
• Playback status — shows > PLAYING or || PAUSED

Supported Formats

• MP3 (.mp3)
