The game was remade from the ground up, development starting in 2007, and released on Nintendo's WiiWare service by Nigoro on June 21, 2011 in Japan. The WiiWare version features a number of changes, partly to tone down the difficulty and improve design in order to appeal to a larger audience, partly to give players who played the original a new experience, and partly due to copyright issues. In addition, the graphics are updated to a smoother style and the music comes in orchestrated form.
