Safe Frame

Information has been collected to help developers create a "Safe Frame". Take these values into consideration when developing games. The standard resolution of the Nintendo 64 is 320 (horizontal) x 240 (vertical) dots. The image signals actually sent to the TV are set to enlarge the screen's effective display area. This means greater attention must be paid to the positioning of information displays as the game progresses. The "Safe Frame" is that area on virtually all TV screens in which important information, such as text or scores, can be properly displayed. The following values for the Nintendo 64 "Safe Frame" are calculated using the standard resolution values described above.

  1. Values used for the Safe Frame for the Super NES:

    (Horizontal direction) X axis : 31 dots inside from left and right
    (Vertical direction) Y axis : 22 dots inside from top and bottom

  2. Values used with Mario64:

    (Horizontal direction) X axis : 22 dots inside from left and right
    (Vertical direction) Y axis : 16 dots inside from top and bottom

    Note: To gain processing time in Mario64, nothing is displayed for 8 dots at the top and bottom of the screen.

  3. Values used with Wave Race 64:

    (Horizontal direction) X axis : 24 dots inside from left and right
    (Vertical direction) Y axis : 21, 23 dots inside from top and bottom

    Note: To gain processing time in Wave Race, nothing is displayed for 20 dots at the top and bottom of the screen, and for 8 dots at the left and right of the screen.

  4. Values when projected on a 15% overscan TV (Non-Japanese brands, 14"):

    (Horizontal direction) X axis : 21 dots inside from left and right
    (Vertical direction) Y axis : 16 dots inside from top and bottom

  5. Values when projected on a 10% overscan TV (Japanese brands, 29"):

    (Horizontal direction) X axis : 15 dots inside from left and right
    (Vertical direction) Y axis : 11 dots inside from top and bottom

  6. Values when projected on a 8% overscan TV (latest Japanese brands, wide TV):

    (Horizontal direction) X axis : 12 dots inside from left and right
    (Vertical direction) Y axis : 9 dots inside from top and bottom
