Yes... This is Super Mario 64 in High Definition, 16:9 wide-screen. It is not stretched from 4:3, it is true 16:9 rendering done through the magic of emulation. Since the N64 was not designed to render things beyond the scope of 4:3 there are some graphical glitches that occur on the sides of the screen.
Also I want to clear something up right now. Its not "So long, Gay Bowser!" its "So long, eh-Bowser!".
