So why would the OSSC and PVM not exhibit these jail bars, but XRGB will? The LPF, is it applied across all data lines, SYNC only, ... ?
Also, is there a way to turn on/off the LPF in the menu?
Well again it seems similar
to the Sega Saturn, which also looks perfectly clean on a PVM (and
the older Framemeister firmware). I don't really know how or what
the LPF is applied
to, and there's no option
to turn it off, other than in
the current firmware it being limited
to standard, game1, and meister modes.
What I'm thinking about doing is breaking out SSX 3 again and doing a detail test with
the older 1.07 firmware. If I see
the same loss
of detail in all modes, then that would prove
the theory that LPF was enabled on all modes in that older firmware.
Coincidentally,
the jail bars are absent when using composite video on
the Saturn into
the Framemeister, indicating there's something very specific
to the RGB signal that it's not liking. It might even be
the same thing it's not liking about
the N64RGB signal.
Edit: Just hooked up
the Saturn and made some interesting observations on
the current Framemeister Firmware:
"Standard" mode shows
the strongest amount
of jail bars, while "Meister" mode shows
the least. If you toggle
the scanline button after setting it
to Meister mode, you can force
the scanlines off and yet still be in Meister mode. In this case,
the jail bars are only barely visible, but they are indeed still there.
More testing
to be done...
Edit 2: I spotted
the "SYNC_LEVEL" function actually shifting
the jail bars horizontally and making them fade in and out, so at least in
the case
of the Saturn, it's very definitely something in
the sync line that
the Framemeister doesn't
like.
Still more testing
to be done...
