Btw, just another idea with STe: since the prefetch causes +1 word to read, the total number of words will be 116/scanline instead of 115 when both borders are opened. And this is divisible by 4, so it won't confuse the shifter (there will be no word left in it). I wonder if it is used already. Just need to set the hscroll value to something which is not zero.
