Super Double Dragon: Return of Double Dragon Music Fix

This game is the Japanese version of Super Double Dragon. It has some advantages over it's US counterpart: Improved weapons use, Better Super kick, elongated final level, options menu but has one flaw. The music selection is mostly different than what is used in the US version, and more boring in some parts because of it. This patch restores the original music selection that you normally have in the US version, so it makes this basically a more complete game.

Also included is a patch if you wanna play the US version with the Double Dragon theme playing in the title screen. They play the wrong song in the US version.

EDIT: The us version must have a header for the patch to work.

This is a hack that I worked on with a fellow hacker (Ugetab) to try to fix the music
in Return of Double Dragon, the Japanese version of Super Double Dragon. The
japanese version of SDD had some advantages over it's US counterpart : Improved
weapons use, Better Super kick, elongated final level, options menu. I did not like one
of the games changes tho, the music selction. The music choice is changed in most
every level. I didn't care for the new soundtrack so I changed the music selection to be
exactly the same as the US version. So it is basically like playing a better US version.

Also included is a patch to change the title music screen in the US version to play the
Double dragon theme song instead of the level 1 song. I think that is how it was intended
by the games programmers anyway, they just didn't have time to switch up the music
cause the game was released in a hurry to become a launch title. Every other DD game
has this theme song at the title.

You may need to use a unheadered rom to make this patch work.
