I am pressed for time so apologies if this doesn't make sense or is already known about, I dont have time to check yet.

I know it's there, but idk if it's been documented anywhere either.
I noticed while messing around with the debug rom that ZZAZZglitch made, that a 1-pixel-thick female symbol is loaded into VRAM whilst you are on the title screen, despite going unused. I havent tried this with the original Yellow rom yet but I can't imagine it not also being there too.

If you look carefully, they're different.
Aren't they (the male symbol and the "6" on the row below) just from the default font?

Looked into it. Apparently it's a bug in all versions of Yellow, not just the debug patch, where before copying the copyright tiles to the screen, it loads too many of them before calling CopyVideoData, even though the copyright text string is properly terminated. So that's why they'd be in VRAM.

Well, shoot, stuff like that's still completely flying over my head. Though I don't see a more clearly relevant line.

That line is irrelevant, no? It only copies one more tile which is an "A".
