 Problem

 Solution

 My Nes doesn't run at all.

  • Make sure your pc meet the System Requirements
  • Try installing the SlimDX Runtime .NET 4.0 x86 (January 2012).
  • Update you drivers to the latest releases (video card and sound card drivers)
  • Try to run My Nes as administrator (right mouse click on My Nes execute file the then choose run as administrator or choose properties then the compatibility tab, check the run as administrator.

 My Nes used to run normally but suddenly it stop to run and windows show message about find solution.

  • Try to reset My Nes settings to defaults. To do so, go to "C:\Users\<username>\AppData\Local\MyNes" folder (windows Vista and later) then delete all folders located there.

 The Launcher show errors when attempt to run it using CTRL+Q

  • Try to delete (or move) the database file. Normally, the database file is located in My Nes folder called "MyNesDatabase.mndb" either rename it to something else, move it somewhere or delete it. Try to launch the Launcher again. If it works then the problem is with the database and you'll need to create new one.
  • Try to reset My Nes settings to defaults. To do so, go to "C:\Users\<username>\AppData\Local\MyNes" folder (windows Vista and later) then delete all folders located there.

 The sound playback get ugly after sometime of playing a game.

  • Maybe the issue is "losing synchronization". See Audio for details. The solution when this problem occur is to Pause the emulation (press F2) for 2 seconds or more then resume the emulation (press F2 again).
  • Maybe the emulation is not running at the required speed. For example, it should run at 60 FPS but it run less (40 FPS) for you. To make sure, enable Show FPS option in the Video setting then run the game. If the FPS is less than 60 FPS for NTSC/50 FPS for PAL then that it is. The only solution is to try to improve performance. See Improve Performance With Frame Skip, Audio .

 The controls doesn't work after disconnecting a joystick

  • You'll need to reconfigure the input settings for that Nes device and set the PC device that should be used for that Nes device. See Inputs.

 State save/Snapshot take/Record sound doesn't work.

  • Try to run My Nes as administrator (right mouse click on My Nes execute file the then choose run as administrator or choose properties then the compatibility tab, check the run as administrator.

 A game doesn't work (Green/Black/Blue screen on My Nes)

  • This mean that game is not supported (not supported mapper) or that game has an issue. There is no solution but to wait for the developers to support the mapper required and/or to fix the issue. You can help by sending a feedback about that game, see Support .

 Game Genie doesn't work after adding codes to the list using the Game Genie window

  • Make sure the Activate Game Genie option is enabled in the Game Genie window. See Game Genie
  • Make sure the codes you entered are correct.

 The video is not rendering as it should (no smooth frames or shattering)

  • Make sure the Frame Skipping is configured well. If it is enabled, it may cause a "not smooth" frames.
  • Maybe the emulation is not running at the required speed. For example, it should run at 60 FPS but it run less (40 FPS) for you. To make sure, enable Show FPS option in the Video setting then run the game. If the FPS is less than 60 FPS for NTSC/50 FPS for PAL then that it is. The only solution is to try to improve performance. See Improve Performance With Frame Skip, Audio .
