WAVPlayer

This is a little WAV player.

It will list all WAV files you placed into the "WAVFiles" Folder.

At the moment 100 Files are supported (you can change this at #define MAX_TRACKS 100)

Please don't rename the Folders, because the Player needs a constant path.

Buttons:

A - Start playing of the selected File

UP - Go up

Down - Go down

The wave files included are only for testing and I got them from the "picomon" Game
