Goemon (known sometimes as "Legend of the Mystical Ninja" in the USA) is a very silly platformer title. This one features the introduction of Impact, a giant robot (whee!) I can´t really tell you a whole lot about this, other than that it´s a fairly popular series. I was never really able to get into Goemon 1.
Main dialogue´s been translated, but that´s probably only about 3/4s or so of the text; the remainder is graphics and big, alternate-font stuff. Haven´t gotten around to trying to put the main text back in the game, though.
