Hello. The updates are: Implemented the 2 byte fractional technique "for better translation to PAL" (but doesn't look too well). Very tight counting in kernel. I removed a sta WSYNC! It works in the emulator at least. I needed those cycles to update the NUSIZ1 register. And the last thing is: no more black line in the left. Yes, the HMOVE doesn't cause the little line. Not by triggering it every scanline, not by using the playfield as a mask but doing the sta HMOVE just before the scanline ends (not following the WSYNC as the big book says). The only side-effect is to change the horizontalPos values. I don't know if any game is doing it. To me it is very scary. -- Gonzalo Fernández.
