After receiving your modded Nintendo with the Hi-DEF NES board you can pull up a special menu. To pull up this menu, make sure you have a game running, then press and hold SELECT then LEFT ARROW on your controller. Please see below what each menu option does. It is recommended that you write down the original default settings just in case. If you have any questions concerning this guide, let us know.
MAIN MENU
The main Hi-DEF NES menu. This menu can only be accessed when connected to through HDMI and not composite or RF.
RESOLUTION
Allows you to select between three resolutions depending on your monitor:
- 640*480 – Not recommended unless your monitor only supports this resolution
- 1280*720 – Recommended for 1080p displays when scanline mode is enabled
- 1920*1080 – In most cases this should be set as your default resolution. Also known as “Full HD”
VIDEO OPTIONS
Horizontal Stretch
Stretches the picture to your preference.
- The 5x option gets rid of the shimmering effect when scrolling horizontally in games, e.g. Mario Bros.
- The 4:3 option stretches the image to the same aspect ratio as a CRT TV. This will introduce a shimmering effect.
- The 16:9 option will stretch the image so that a widescreen monitor will be filled with the image entirely.
Scaling
Allows you to select a variety of filters which will change the way pixels are represented visually. Default is set to none.
Scanlines
This option enables artificial scanlines which mimics the thick dark lines displayed by a CRT TV. Change the depth option slider in order to make the lines darker.
Interpolation
This enables a blur along the horizontal axis which can hide the shimmering effect when scrolling horizontally.
Palette
Allows you to change the way colors of the image are represented during gameplay. Here are Palette examples.
Cropping
Depending on the game, (Left edge in Kirby’s Adventure for example) you can get rid of “junk” information on the image.
Horizontal Position
Can change the overall position of the image from left to right.
Despeckle
Changes the phasing of the PPU (picture processing unit). Changing this could fix some slight graphical glitches in some games.
AUDIO OPTIONS
Chip Enables
Allows you to enable emulated special sound chips that were in select Nintendo games. For example FDS emulated the sounds from the Japanese Famicom Disk System peripheral.
Volume
With this option, you can change the volume of various parts of the audio. Example would be louder drum tracks, softer sound effects.
Panning
Allows you to balance the different sections of audio such as drums, sound effects , etc which in turn could make a simulated stereo effect.
APU
This is a viewer to see which sounds chips are being used during gameplay.
SETTINGS
Menu Hotkey
Could change various hotkeys to access special functions.
DVI Mode
Enabling this could help with some HDMI picky displays.
EDID Disable
Disabling this will allow you to force any resolution on your display.
Sound Clock Select
You can select whether the CPU or PPU gets to handle the audio. This should be set to CPU by default. Set it to PPU if you are underclocking or overclocking the CPU as the pitch of the audio is affected.
