[Tuxnes-devel] [PATCH] pixels.h sprite right edge

[Jim U. <ji...@3e...>]

tuxnes currently cuts off a sprite once its rightmost edge leaves the
screen.  As an example, load up Super Mario Bros. and notice how the
right half of a Goomba disappears when partially offscreen.  Tests on
a real NES indicate it should not be cut off.  Attached patch corrects
the problem.  It's not an ideal optimized solution, because that'd
require quite a bit of work.  (I only changed 3 lines, the rest is
indentation to compensate for the new "if".)

BTW, sprites off the left edge of the screen are cut off too, but this
is proper behavior according to the real NES.  Makes sense when you
think about it.  Top edge handling appears to be incorrect as well
but I'm still working on this.  Haven't looked at bottom yet.
