osViExtendVStart
Syntax#include <ultra64.h> /* os.h */ void osViExtendVStart(u32 value);
Arguments
- value
Number of scan lines to add (0 - 48)
Return Value
None
Explanation
Specifies the number of PAL-mode scan lines to be added. With low resolutions, specifying 48 for value has the same effect as using FPAL mode. Specifying an additional 32 or 24 scan lines results in display over virtually the entire screen, and the increase in the number of rendering pixels can be limited. No blurring of the screen occurs in this case.
Note
This can be used only in PAL mode. Proper operation cannot be assured with NTSC, MPAL, or FPAL mode.
