Incidentally, the theory mentioned on that page that his name is actually "Errol" is nonsense. No Japanese person would write "Errol" as "ERAA." If they did not intend "Error," then it would have to be some fantasy-sounding name like "Erah."

There's a bunch of java applets that do this (popular hobby project I guess), and one commonality among them always bothered me: Why don't they make the screen bigger? Not that much of a performance hit.

The standard display resolution of the NES is 256 horizontal pixels by 240 vertical pixels. Upscaling on a canvas context can be a very slow operation even if you use the nearest-neighbor approach.

Americans, please stop using X and Z for game controls. On German keyboards, Y and Z are swapped, which makes those games unplayable.

This makes no sense for us, because Z (especially "tz") is more common than Y in German language and QWERTY does not come with öäüß :)
