Hareware: Gamecube Ouput: YPbPr




NTSC YPbPr Profiles for the Gamecube:




These profiles were designed for the American NTSC Gamecube original purple colored console, which has the original digital output part that the official Nintendo component cables make use of. 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.

Smoothed Instead of Sharp:

My profiles for the 480i and 480p modes of the Gamecube are based on smoothing pixel edges rather than sharply defining them. This is because unlike 240p-based content, the Gamecube's graphics actually look worse when sharpened due to the poorly defined edge detail coming from the YPbPr output. Combined with this is the predominantly polygonal nature of most Gamecube games, which typically look better with smoothed edges. Below is a comparison screeshot showing the difference when using my smoothed settings versus a sharply focused sample:


Gamecube Smooth vs Sharp


Nevertheless if you still prefer unsmoothed pixels, simply adjust the H_Scale to 4 and V_Scale to 7, and then turn Sharpness back down to zero.

GCBCOMIN (Gamecube 480i mode 2x scaled with aspect correction)

This profile scales the image to 2x the original 480i vertical res.

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 GCBCOMIN Should Appear on a 1920x1080p Display:

GCBCOMIN Display

Due to the 2x integer scaling, you will notice black borders on the top and bottom of the screen. If this bothers you, you can asjust Zoom_Overscan to 100 to fill the screen, but scanlines will no longer align properly if you use those.

FZGXWIDE (Gamecube 480p mode 16:9 Fullscreen for F-Zero GX game)

This profile fills the screen of a 16:9 display for the F-Zero GX game's progressive widescreen mode.

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 Full Pixel (or zero% overscan, or 1:1 ratio, or whatever your brand of display refers to the turning off of any sort of overscan zoom).

The Visual_Set dimentions combined with Zoom_Size of 93 are set based on my Sony 55-inch display. If your display doesn't align to this specification, you'll need to experiment with your own Zoom settings to see if you can get proper alignment.
