Super Double Dragon in the USA!!!! Japanese version has extras not found on English read below:

Super Double Dragon, known as Return of Double Dragon (リターン・オブ・双截龍, Ritān obu Daburu Doragon^?) in Japan, is the fourth game in Technos Japan's Double Dragon series of beat-em-ups. It is also termed Double Dragon IV. Unlike the previous Double Dragon, which were all originally released as arcade games and then adapted to the Nintendo Entertainment System (or other platforms), Super Double Dragon was made exclusively for the Super Nintendo Entertainment System with no prior arcade version and no other console ports. It was released in North America and Japan in October 1992. The North American and European release of the game were co-published by Tradewest and American Technos, instead of Acclaim Entertainment (the company that published the two NES sequels).

Version differences

While neither the Japanese (Return) nor the English (Super) versions of the game are true to the designers' original vision, the Japanese version was based on a more completed build of the game and features various notable enhancements and changes. Among them:

• An Option Mode is added, in which the player adjusts the number of buy-in credits and difficulty level from one of three settings. The game also features Music and Sound tests.

• While the English version only has one difficulty setting, it is considerably harder than the ones in the Japanese version, which includes different enemy ratio and more damage done by weapons.

• Most of the background music are played in different context in the Japanese version. The American version uses a new title theme (which is also the final stage theme), while the Japanese title screen plays an arranged version of the standard Double Dragon theme (which is also used in the final battle and is played in the American version in Stage 5). The themes for Stages 1, 3 and 4 from the American version are used in Stages 4, 5 and 7 respectively in the Japanese version, while new themes composed for Stages 1 and 3. The themes for Stages 2 and 6 and the ending theme are the same for both versions. All of the game's music can be heard in the Japanese version's music test on the option screen, including a tune unused in both versions.

• In the Japanese version, if the player has a weapon currently equipped, it can be exchanged with another on the floor.

• Likewise, the player will pick up the boomerang when it is thrown and then returns to the player's direction.

• The hurricane kick knocks over enemies with single hits in the English version, while it does multiple hits in the Japanese version.

• And finally, the final stage has two new areas.
  
• After the grand hall, the player will go through a series of stairways and then a huge room where all of the previous stages' bosses are confronted before the battle with Duke.
