Scandoubler Fx 100% Option

Hey all! I just got a pre-configured MiSTer this week, and been having a blast since.

Because I use a pc vga monitor (31khz), i opted to use the scandoubler feature through the io board of MiSTer. (forced_scandoubler=1)
I prefer this setup over using vga scaler or hdmi out for numerous reasons, but there is 1 thing that I noticed.

All the cores I've tried have Scandoubler Fx feature in their OSD (25%, 50%, 75%) which darkens every other line to basically make line-doubled images to look like a native 240p scanlined image on PVMs. However, there is no 100% option that allows vga users to recreate a "full scanline effect" like the OSSC does with its line-doubling feature.

Is there a reason why 100% is omitted from Scandoubler Fx? it would be hugely appreciated by people like me who are using pc VGA monitors.

I made a similar thread a couple of weeks ago. I’m also hoping for a FX 100% scanlines mode. The other filters are much too soft and not pleasing to me.
