    And then NTSC modes:
    NTSC:HiRes, NTSC:LowRes in lineX2 mode:
    240p/288p lineX3: Off
    H. samplerate: 910
    H. synclen: 60
    H. active: 724
    V. active: 241
    H. backporch: 76
    V. backporch: 16
    Sampling phase: Adjust until you get stable and crisp picture

    NTSC:HiRes, NTSC:LowRes in lineX3, NTSC:Super-HiRes mode:
    240p/288p lineX3: ON
    H. samplerate: 1820
    H. synclen: 72
    H. active: 1448
    V. active: 241
    H. backporch: 198
    V. backporch: 16
    Sampling phase: Adjust until you get stable and crisp picture

    DBLNTSC:High Res No Flicker, NTSCPAL:Low Res No Flicker:
    OSSC does not sync

    That should be all except interlaced modes, perhaps somebody else would have energy for those 🙂 Oh and as you noticed, my settings will always show whole overscan area since I want Workbench screen to be as large as possible. For gaming you could shrink active values to match nominal resolution and backporch to center it to avoid getting black bars. Samplerate should not be modified.
