    Some Dreamcast 240p games actually run at 640×240. From what I could see the games tend to be 320×240, but menu’s, text overlays etc. sometimes run at 640×240.

    After forcing third strike into 240p with Start+L, these settings worked for me:

    Sampling Opt.
    – 480p in sampler: DTV 480p

    Adv Timing: 512×240
    – H. samplerate: 858
    – H. synclen: 62
    – H. backporch: 106
    – H. active: 640
    – V. synclen: 3
    – V. backporch: 14
    – V. active: 240

    Sync opt.
    – H-PLL Post-Coast: 1

    Output opt.
    – 240p/288p proc.: Line5x
    – Line5x mode: 512×240 optim.
    – Line5x format: 1920×1200

    You could actually optimise this further for most 240p Capcom games, as they draw something like 614×224, rather than using the full 640×240 display. I think the horizontal resolution is integer scaled internally from 384×224 to 614×224, without interpolation, so it is always going to look a bit inconsistent.
