Ah, of course… I forgot about the half-scanline in interlaced mode. Silly of me!

In theory, I suppose the OSSC *could* buffer half a scanline and have the output frame rate be 265.5/262 of the original, in order to support higher scaling for interlaced… sort of how the Hidef-NES manages to compensate for the original signal’s line rate being different to the output. But that would be a lot to ask for a mode that’s going to look pretty rubbish no matter what… 🙂

Unfortunately, changing H-PLL 2x setting didn’t help either. But I’m now pretty convinced it must the shorter scanline causing all this, and will patiently wait for Marq’s hardware mod to be available.

But thanks for all the advice Paul!
