[tekken] Fix Music Pitch

[AnthonyRyuki]

In the arcade version of the original Tekken, the music is higher pitched by a semitone than in the original soundtrack and the PlayStation version. Even in the Sound Test's song 1, the scale is not a C major scale like in the other Namco System 11 games. However, QuattroPlay has an option that allows you to listen to the game's soundtrack with its pitch fixed. From my understanding, a value in a byte should be changed to fix it. I was wondering if it was possible to do that in-game with a cheat.
