SOUNDS WILL ONLY WORK ONCE YOU START A FIGHT WITH AN ENEMY, THIS IS A KNOWN ISSUES WITH THIS GAME. SO DONT EXPECT THE GAME TO HAVE SOUND UNTIL A FIGHT !

HERES WHAT THE AUTHOR OF THE HACK WROTE IN HIS DESCRIPTION
-The main thing that you will notice about the game is that there is no background music or sound effects for the vast majority of the game. This was to be the last thing I incorporated into the game but I did not get a chance to complete it.

Works perfectly !
