I have added information for both the Japanese and American release for this game. The USA release has quite a few disparities on names for characters and a few graphical glitches that might have been intentional when making the localized version. The Japanese version is based off of the Double Dragon & River City Bundle. I was able to discover some of the names of players by analyzing the Sega Genesis Japanese version of this game.
Next up will be the new release of River City Saga: Three Kingdoms! I may also be working on River City Girls at the same time.
