<p>If the display is set to 640&#215;480, this hack will test if there is a border around the display using the comparison function and value specified, and if so, expands the inner 512&#215;448 pixels to the 640&#215;480 screen. In addition, if the display is set to 320&#215;240, this will expand the inner 256&#215;224 pixels to the display.</p>
<p>This hack is intended for emulators and similar applications that render at 256&#215;224 or 512&#215;448 resolution, while allowing menus to continue to display properly.</p>
<p>For best quality, use a scaled display mode when using this hack.</p>
<p>Currently, this hack only reads the upper-left pixel of the display.</p>
<p>The following options are available:</p>
<h3>512&#215;448 to 640&#215;480</h3>
<p>Expands 512&#215;448 resolutions to the 640&#215;480 display.</p>
<h3>512&#215;480 to 640&#215;480</h3>
<p>Expands 512&#215;480 resolutions to the 640&#215;480 display (scaling only in the horizontal direction).  This can be useful for displaying all 480 lines in NES emulation, or when outputting to a CRT display.</p>
