<p><span class="rvts12"><br></span></p>
<p><span class="rvts12">Overview</span></p>
<p><span class="rvts12"><br></span></p>
<p>Memory watch is a tool designed to values of specific known memory values in the game's <a class="rvts18" href="NESRAMMappingFindingValues.html">RAM</a>. Memory watch does not find values. &nbsp;To find useful values to monitor, see <a class="rvts18" href="CheatSearch.html">Cheats</a>, <span class="rvts18">Ram filter</span>, <a class="rvts18" href="HexEditor.html">Hex Editor</a>, and <a class="rvts18" href="Debugger.html">Debugger</a>.</p>
<p><br></p>
<p><br></p>
<p><span class="rvts16">Inserting Values</span></p>
<p><br></p>
<p>To display a ram value, simply type its address into one of the address fields. &nbsp;The name field allows you to put a brief description of the value. &nbsp; </p>
<p><br></p>
<p><br></p>
<p><span class="rvts28">Prefixes</span></p>
2012-03-23 20:30:31 +00:00
<p><br></p>
<p>You must put in the hexi-decimal value of the address, &nbsp;but the value will be displayed will be decimal by default.</p>
<p><br></p>
<p>To display the value in hex, use a prefix of "x" (such as x00FD). &nbsp;</p>
<p><br></p>
<p>Use the prefix "!" to display a 2 byte value. </p>
<p><br></p>
<p>Use a prefix of "X" to watch a 2 byte value in hex.</p>
<p><br></p>
<p><br></p>
<p><span class="rvts28">Saving/Loading Watch files</span></p>
2012-03-23 20:30:31 +00:00
<p><br></p>
<p>You can save your addresses into watch files, as well as loading previous files using the standard save,load,new options in the File menu.</p>
<p><br></p>
<p>FCEUX uses the /memw folder by default but you can specify a new default folder in the <a class="rvts18" href="Directories.html">Directory Override</a> menu.</p>
<p><br></p>
<p><br></p>
<p><span class="rvts28">Options Menu</span></p>
2012-03-23 20:30:31 +00:00
<p><br></p>
<p>If you select <span class="rvts38">Load on Start up</span>, Memory watch will load up automatically when FCEU is started. </p>
2012-03-23 20:30:31 +00:00
<p><br></p>
<p>If you select <span class="rvts38">Load Last File on Start up</span>, the most recent file in the Recent folder will be loaded when memory watch is loaded.</p>
2012-03-23 20:30:31 +00:00
<p><br></p>
<p>If you select <span class="rvts38">Collapse to 1 Column </span>(or press the right arrow button on the bottom left of the dialog), the memory watch dialog is reduced to just 1 column.</p>
2012-03-23 20:30:31 +00:00
<p><br></p>
<p><span class="rvts16">Frozen Memory Addresses</span></p>
<p><br></p>
<p>If one of the watched addresses is frozen by the <a class="rvts18" href="CheatSearch.html">cheats dialog</a> or the <a class="rvts18" href="HexEditor.html">hex editor</a>, it will display blue in the memory watch dialog.</p>
<p><br></p>
<p><br></p>
<p><span class="rvts12">Memory Change Monitor</span></p>
<p><br></p>
<p>The bottom of the memory watch dialog displays a memory change monitoring section. &nbsp;This monitors the 1st two values of each memory watch column. &nbsp;Rather than monitoring the value itself, this monitors the value's behavior. &nbsp;</p>
<p><br></p>
<p>The address being monitored is under the address column.</p>
<p><br></p>
<p>The Formula drop down box shows which criteria the change monitoring is using.</p>
<p><br></p>
<p>The count value displays how many times the value has changed based on the criteria.</p>
<p><br></p>
<p>Reset will reset the count to 0.</p>
<p><br></p>
<p><br></p>
<p><span class="rvts43">Usage Example:</span></p>
2012-03-23 20:30:31 +00:00
<p><br></p>
<p>As an example of the memory change monitoring, Let's say we are recording a movie of the game Super C and want to keep track of when the game lags.</p>
<p>The ram address 001C functions as a "lag flag". &nbsp;It will remain 0, then change to a positive value on a frame that the game lags.</p>
<p><br></p>
<p>We could put 001C in one of the 1st two memory watch edit boxes. &nbsp;Then set the corresponding formula in the memory change monitoring to "&gt; then" (greater than). &nbsp;Now the count will show us how many lag frames occur in the movie.</p>
