Miyamoto: that’s “basically up to the maker.”
Not all 3DS games will have to make use of the device’s 3D capabilities, Nintendo has revealed.
Answering a question from Earthbound creator Shigesato Itoi in a new Iwata Asks interview as to whether the handheld will be compatible with DS cartridges, Nintendo guru Shigeru Miyamoto explained, “It’s compatible with software for previous Nintendo DS systems, which will be viewed in the 2D mode.
“New game cards, however, will be specific to Nintendo 3DS, but whether they will be in 3D or not is basically up to the maker, just like how much to use the touchscreen was up to developers for Nintendo DS.”
