A complete translation in English of this game for the Snes version already exists and it's called Shiren The Wanderer. The version for NDS called 0767 - Fushigi no Dungeon: Fuurai no Shiren NDS is exactly the same game with some addons. It would be possible to open the .ips of that one for super NES and to re-use it in some way to hack the NDS rom? (not directly obviously). This is a great game and prolly there'll be not an english version, i hope someone will hack this into english.
