V-blanks: 50 (PAL) per second This makes sense, PAL runs at 50 fps so would expect 50 vertical blanks (one per frame) H-blanks: 312 (PAL) per v-blank This I DON'T get. Where does this figure (312) come from? WHY 312 h-blanks every frame? I naturally assume that if I'm using 320x256 res. then there would be 255/256 h-blanks. Where is my logic deserting me? Cheers, Scott
