    The display must be turned on before calling this function
    (with @ref DISPLAY_ON).

    When using the SGB with a PAL SNES, a delay should be added
    just after program startup such as:

    \code{.c}
    // Wait 4 frames
    // For PAL SNES this delay is required on startup
    for (uint8_t i = 4; i != 0; i--) vsync();
    \endcode
