|

|
|
<p>The NES architecture includes a 6502 CPU as well as a custom video controller known as a PPU (Picture Processing Unit). The PPU's video memory is separated from the main CPU memory and can be read/written via special ports (see <a class=rvts14 href="{9C73EB3E-118D-451A-AAE8-BBF99A5FDEEB}.htm">PPU Memory</a>).</p>
|
||
|
|
<p><br></p>
|
||
|
|
<p>The PPU viewer will display the contents of the current PPU memory. (It does not alter game data in anyway). </p>
|
||
|
|
<p><br></p>
|
||
|

|
||
|
|
<p><span class=rvts13>Show on Scanline</span></p>
|
||
|
|
<p>This options makes it show what the PPU looks like when the screen is drawing that scanline. It is useful for games like SMB, that swap pattern </p>
|
||
|
|
<p>tables mid-frame (status bar stuff).</p>
|
||
|
|
<p><br></p>
|
||
|
|
<p>Right clicking on one of the PPU panels cycles the palettes it is shown with, though pattern palettes and then sprite ones</p>
|
||
|
|
<p>Putting the mouse cursor over a tile will display the tile address. Moving cursor over palette color will give palette address.</p>
