Hi, I'm reading up PPU in the wiki and I'm confused:
In http://wiki.nesdev.com/w/index.php/PPU_rendering, the first scan line is line -1 and VBlank is between 241-260
In http://wiki.nesdev.com/w/index.php/PPU_frame_timing, the Even/Odd Frames says line 20 is one PPU clock shorter on odd frames
In http://wiki.nesdev.com/w/index.php/PPU_ntsc_pal_difference, the Total number of dots per frame in the table says pre-render line is one dot shorter in every other frame
Does line 20 in the PPU_frame_timing page the same as pre-render line in PPU_ntsc_pal_difference page and the line -1 in PPU_rendering page?
