-Since you cannot rely on $02a6 to detect NTSC/PAL, you better do the check yourself. The theory behind these checks is simply that PAL and NTSC systems have different amounts of rasterlines, which can thus serve as the basis for a detection check. +Since you cannot rely on $02a6 to detect NTSC/PAL, you better do the check yourself.
