Capcom released Rockman 9 for mobile phones in Japan today and from the looks of it, the new on-the-go version is a faithful port of its home console counterparts.
The game is currently exclusive to Docomo and Au phones, available for 315 Yen ($ 3.75 USD) per month via Capcom Party. It remains to be seen if the game will support the many downloadable features of the original, or if the content comes preloaded.
If you've got the means to obtain the game, you can do so right here. If not, just keep on hoping for a world-wide release!
