CRTC

7 bytes added, 6 July
/* CRTC counter differences */
At the end of the display of the last raster line of each character line (ie. when HCC=R1 and VLC=R9), MA' captures the current value of MA.
CRTC 2 is the exception, where MA' captures R12/R13 instead of MA at the last raster line of the frame.
