Arcade Version and DevelopmentThe original arcade version of the game was not developed by Technos Japan, the developers of the first two arcade games and their Famicom/NES counterparts. Instead, Technos contracted the game to an outside developer called East Technology and produced the game with the western market in mind. As a result, the arcade version of Double Dragon III: The Sacred Stones bears little or no resemblance to the previous games.
In addition to a new graphical style and a world tour-theme, the arcade version features a shopping system where players could purchase power-ups such as extra men (from one of four character types or families), weapons, special techniques, extra energy and speed by inserting additional tokens to the machine. The game version bombed as a result of this feature and when the game was relocalized for the Japanese market, the shopping feature was removed and a player select feature (which was originally planned for the US version) was implemented to the game.
When the time came to develop a Famicom/NES version, Technos Japan decided to work on the game themselves. While the first two NES games took a few liberties with their arcade counterparts, they still retained the same gameplay and appearance as the original versions. The NES version of Double Dragon III: The Sacred Stones on the other hand is almost a completely different game as its arcade counterpart. The NES version is the only version made by Technos Japan.
