* Mode 0 - 160x192x16 - special software mode: the software performs sixteen Mode 2 scans (with different brightness settings in each pass), and combines them to a 16-color image. Obviously, this method works only with still images (camcorder aimed at still image, or VCR with "freeze picture" mode). Moreover, the CPC with [[CTM640/CTM644]] colour monitor can't display 16 grayscales so the picture will look like crap, however, it will look pretty much perfect on a [[GT64/GT65]] green monitor. The software scans only 192 lines in this mode (not 200 lines), but this is just due to lazy programming (the programmer didn't handle the region "under" the OSD menu at the bottom of the screen). In mode 0 scanning, aside from thatthe user/software selected brightness is ignored (because the whole sixteen I/O selectable brightness values are used for the sixteen passes), it'd so, brightness can be certainly possible to scan all 200 lines even in Mode 0adjusted only via the potentiometer.
