Requirementsnemulator uses DirectX 10, therefore Windows Vista, 7, 8, or 10 is required. If you receive an error message stating that d3dx10_43.dll is missing, please download the latest DirectX 10 update from Microsoft at microsoft.com.  Notes and known issues

• IMPORTANT! If your monitor refresh rate is not set to 60Hz (LCD monitors usually are, CRTs are usually not), set app.timer_sync to true in nemulator.ini.
• nemulator, by default, looks for ROMs in c: oms
  es and c: omssms. This can be changed in nemulator.ini.
• To ensure the smoothest graphics, nemulator dynamically adjusts the audio playback rate to stay in sync with the video refresh rate. Most emulators lock the audio playback rate which can lead to stuttering/tearing of the display (when scrolling, for example). Resampling audio on the fly can be tricky, though... feedback on how well this works for you is appreciated.
