DDS translations has been doing a fine job of steadily releasing games for the past two years or so. Besides this game and the Goemon SNES series, they also released a translation for Tetris Battle Gaiden and Super Chinese Fighter, which is very similar to another fighting game called SD Hiryuu no Ken (both are made by the same developer). Hopefully, that one will also receive a translation someday as well. It was supposed to be released officially in the US as "Galactic Defender" back in the 90s, but was cancelled.
As for Bushi Seiryuuden, it was made by the same developer that worked on Pokemon and was released right after the original Red and Blue Gameboy games were. Enemies can usually be seen on the world map and are fought in a Street Fighter style battle system where enemies move at the same time as the player, much like in rogue style games such as Shiren the Wanderer or the Mystery Dungeon series.
