Shining Force: The Sword of Hajya - Unsettling Battle Music

On July 20th, 2013 I was playing around with a Game Genie on the game Shining Force: The Sword of Hajya. I was inputting in random codes to see what would happen. I forgot what the code I used was, but it had a single effect: it changed the battle music for when your party acts into this extremely creepy tone. It caught me by surprise the first time I heard it because the first 10 seconds of the song sound normal, but suddenly shift into this eerie tone. I believe the code corrupted one or two of the sound channels, but it only affected this song.

I recorded it on a low quality phone, but forgot about the file on my computer for almost 10 years. It sounds cursed. The box art scan on the video is also slightly damaged; I think it adds to the cursed feel.
