3) I did not get involved with MednafenX_NES until after version 11.
I did not realise this! Apologies for the wrong assumption.
Regarding the points:
1) The problem doesn't appear to be regarding where the scanlines start or stop when the emulator displays it on my TV. What I am seeing on my TV appears to be in perfect alignment - I get the entire image, including the bottom of the screen. It seems to be that when I hit the "screengrab" button, it starts the grab at the wrong place. Whatever imagery it's reading from the memory buffer, or whatever, and placing it as a PNG on my HDD, it's grabbing the wrong part.
2/4/5) Well, it's not that subjective. Mednafenx_NES V9 had a perfect palette which is identical to all the other NES emulators I have.
Fair enough about comparing V9 to a different emulator (FCEU), they might have different standards. But I only mentioned it because both FCEU and V9 of Mednafen produced the exact same colour palette. They're identical. I'm curious as to how and why someone, anyone, would want to change what was already perfect, and replace it with a muddy brown filtered palette. Maybe I'll root through the older V10-V13 topics to find mention of this.
I tried playing with the palette options in V15, but couldn't find anything which allowed it to look like V9. I will have another look to see what I missed.
For comparison, note the colour of the building. V9 at the top, V15 at the bottom:
