<p class="rvps2"><span class="rvts22">Memory Watch</span></p>
<p class="rvps2"><span class="rvts17"><br/></span></p>
<p class="rvps2"><span class="rvts17">Overview</span></p>
<p class="rvps2"><span class="rvts17"><br/></span></p>
<p class="rvps2"><span class="rvts6">Memory watch is a tool designed to values of specific known memory values in the game's </span><a class="rvts70" href="NESRAMMappingFindingValues.html">RAM</a><span class="rvts6">. Memory watch does not find values. To find useful values to monitor, see </span><a class="rvts70" href="CheatSearch.html">Cheats</a><span class="rvts6">, </span><span class="rvts70">Ram filter</span><span class="rvts6">, </span><a class="rvts70" href="HexEditor.html">Hex Editor</a><span class="rvts6">, and </span><a class="rvts70" href="Debugger.html">Debugger</a><span class="rvts6">.</span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts21">Inserting Values</span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6">To display a ram value, simply type its address into one of the address fields. The name field allows you to put a brief description of the value. </span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts39">Prefixes</span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6">You must put in the hexi-decimal value of the address, but the value will be displayed will be decimal by default.</span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6">To display the value in hex, use a prefix of "x" (such as x00FD). </span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6">Use the prefix "!" to display a 2 byte value. </span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6">Use a prefix of "X" to watch a 2 byte value in hex.</span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts39">Saving/Loading Watch files</span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6">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.</span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6">FCEUX uses the /memw folder by default but you can specify a new default folder in the </span><a class="rvts70" href="Directories.html">Directory Override</a><span class="rvts6"> menu.</span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts39">Options Menu</span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6">If you select </span><span class="rvts47">Load on Start up</span><span class="rvts6">, Memory watch will load up automatically when FCEU is started. </span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6">If you select </span><span class="rvts47">Load Last File on Start up</span><span class="rvts6">, the most recent file in the Recent folder will be loaded when memory watch is loaded.</span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6">If you select </span><span class="rvts47">Collapse to 1 Column </span><span class="rvts6">(or press the right arrow button on the bottom left of the dialog), the memory watch dialog is reduced to just 1 column.</span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts21">Frozen Memory Addresses</span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6">If one of the watched addresses is frozen by the </span><a class="rvts70" href="CheatSearch.html">cheats dialog</a><span class="rvts6"> or the </span><a class="rvts70" href="HexEditor.html">hex editor</a><span class="rvts6">, it will display blue in the memory watch dialog.</span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts17">Memory Change Monitor</span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6">The bottom of the memory watch dialog displays a memory change monitoring section. This monitors the 1st two values of each memory watch column. Rather than monitoring the value itself, this monitors the value's behavior. </span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6">The address being monitored is under the address column.</span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6">The Formula drop down box shows which criteria the change monitoring is using.</span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6">The count value displays how many times the value has changed based on the criteria.</span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6">Reset will reset the count to 0.</span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts71">Usage Example:</span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6">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.</span></p>
<p class="rvps2"><span class="rvts6">The ram address 001C functions as a "lag flag". It will remain 0, then change to a positive value on a frame that the game lags.</span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6">We could put 001C in one of the 1st two memory watch edit boxes. Then set the corresponding formula in the memory change monitoring to "> then" (greater than). Now the count will show us how many lag frames occur in the movie.</span><span class="rvts6"></span></p>
