Changing Mednafen's output rate, via the "sound.rate" setting, to "44100" will bypass the resampler, which will decrease CPU usage by Mednafen, and can increase or decrease audio quality, depending on various operating system and hardware factors.</p></td></tr><tr><td class="RowSpacer" colspan="5"> </td></tr> </table></p><p><table border><tr class="TableHeader"><th>Setting:</th><th>Value Type:</th><th>Possible Values:</th><th>Default Value:</th><th>Description:</th></tr><tr class="RowA"><td class="ColA"><a name="psx.debugger.disfontsize">psx.debugger.disfontsize</a></td><td class="ColB">enum</td><td class="ColC"></td><td class="ColD">small</td><td class="ColE">Disassembly font size.<p></p><ul></ul></td></tr><tr><td class="RowSpacer" colspan="5"> </td></tr> <tr class="RowB"><td class="ColA"><a name="psx.debugger.memcharenc">psx.debugger.memcharenc</a></td><td class="ColB">string</td><td class="ColC"> </td><td class="ColD">shift_jis</td><td class="ColE">Character encoding for the debugger's memory editor.<p></p></td></tr><tr><td class="RowSpacer" colspan="5"> </td></tr> <tr class="RowA"><td class="ColA"><a name="psx.enable">psx.enable</a></td><td class="ColB">boolean</td><td class="ColC">0<br>1</td><td class="ColD">1</td><td class="ColE">Enable (automatic) usage of this module.<p></p></td></tr><tr><td class="RowSpacer" colspan="5"> </td></tr> <tr class="RowB"><td class="ColA"><a name="psx.forcemono">psx.forcemono</a></td><td class="ColB">boolean</td><td class="ColC">0<br>1</td><td class="ColD">0</td><td class="ColE">Force monophonic sound output.<p></p></td></tr><tr><td class="RowSpacer" colspan="5"> </td></tr> <tr class="RowA"><td class="ColA"><a name="psx.pixshader">psx.pixshader</a></td><td class="ColB">enum</td><td class="ColC">none<br />ipxnoty<br />ipynotx<br />ipsharper<br />ipxnotysharper<br />ipynotxsharper<br />scale2x</td><td class="ColD">none</td><td class="ColE">Enable specified OpenGL pixel shader.<p>Obviously, this will only work with the OpenGL "video.driver" setting, and only on cards and OpenGL implementations that support pixel shaders, otherwise you will get a black screen, or Mednafen may display an error message when starting up.
