Hareware: Nintendo Entertainment System Ouput: RGB 21-pin Modified: NESRGB Board




NTSC RGB Profiles for the NES:




These profiles were designed for the American NTSC NES console that has been modified with Tim Worthington's "NESRGB" board for RGB + CSync output. As with all my profiles, the intended output from the Framemeister is 1080p/60. Make sure your Framemeister is set to this output mode, and make sure to check "ZOOM" is set to "ON" after you load the profile of your choice. Also remember that the profiles themselves can be downloaded from the main page, while these hardware-specific pages are to document the settings contained within each profile.

Below are details on each of the NESRGB profiles:

NESRGB4L (NES RGB 4X scaled with masked left-side scroll border)

This profile scales the image to 4x the original 240 vertical res. The "L" at the end of the profile name indicates this profile also masks the left side to get rid of the software-driven scroll border used in certain games like "Super Mario Bros. 3". Note that a few of the top and bottom lines of graphics are cut off from view. This is normal for the original Nintendo, and in fact even more image data was typically cut off from the top and bottom on a CRT display during the prime years of the NES's life.

If you have access to your HDTV's ability to change its overscan mode (stuff like 5%, 10%, none, full pixel, etc.), the suggested display setting would be max zoom. For my Sony display, this is the -1 setting. For other brands, they may refer to it as 10% overscan for example. Please do not confuse the overscan zoom functions described here with your display's standard zoom functions (i.e. "Cinema", "Wide Stretch", etc.).

How NESRGB4L Should Appear on a 1920x1080p Display:

NESRGB4L Display

As you can see from the screenshot above (resized to 50%), the left side is masked. This is because certain games like Super Mario Bros 3 tend to use the left side as a scroll buffer, which looks like an ugly solid stripe of color there most of the time. So use this profile (or the NESRGB5L profile) only when you encounter an NES game that uses a left-side scroll buffer like that.

Also due to the 4x integer scaling, you will notice black borders on the top and bottom of the screen. If this bothers you, please use the NESRGB5L profile, as it will not have the black bars, but at the cost of cropping a small portion of graphics from the top and bottom of the game image.

NESRGB5L (NES RGB 5X scaled with masked left-side scroll border)

This profile scales the image to 5x the original 240 vertical res. The "L" at the end of the profile name indicates this profile also masks the left side to get rid of the software-driven scroll border used in certain games like "Super Mario Bros. 3". Note that a portion of the top and bottom lines of graphics are cut off from view. This is due to 5x scaling resulting in an image slightly larger that 1080 lines. However, back when the NES was new, televisions of that era also cut off a portion of the top and bottom graphics, so the effect here is very similar.

If you have access to your HDTV's ability to change its overscan mode (stuff like 5%, 10%, none, full pixel, etc.), the suggested display setting would be zoom turned off. For my Sony display, this is the FULL PIXEL setting. For other brands, they may refer to it as 1:1 pixel ratio for example. Please do not confuse the overscan zoom functions described here with your display's standard zoom functions (i.e. "Cinema", "Wide Stretch", etc.).

NESRGBOS (NES RGB 4X scaled Overscan)

This profile scales the image to 4x the original 240 vertical res. This is a special "overscan" profile that shows all 240 lines of resolution from the NES. This is for games like Legend of Zelda, that have important artwork extended to the extreme vertical edges of the picture.

If you have access to your HDTV's ability to change its overscan mode (stuff like 5%, 10%, none, full pixel, etc.), the suggested display setting would be max zoom. For my Sony display, this is the -1 setting. For other brands, they may refer to it as 10% overscan for example.
