Arika, the studio behind Endless Ocean and Street Fighter EX, have been working with the Nintendo 3DS. Did you download 3D Classics: Excitebike? Yeah, they made that.
More interesting is a fighting game project shown in a test project corner on Arika’s website. If you have a 3DS, save the MPO files from this site and copy those on your SD card to view the images in 3D.
Since Arika notes this is a test project it’s unclear if we’ll ever see this fighting game and 3D electric blasts on Nintendo 3DS.
