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 work.
