This is because ZC mirrors the screen resolution of Zelda 1, which works like that. It was deemed an acceptable loss to not display that part of the screen in Z1 because (assumingly) very little action or important things happens there.

Yep, it's a Z1 thing. Not a bug, fully intentional.

In fact, if you look in the ZQuest editor, you'll notice a bit of shading on the bottom 8 pixels of the screen; this is to indicate that that area is not visible.

Out of curiosity, how difficult would it be to allow ZC to display those 8 pixels? Seems like the kind of thing that'd either be trivial or next to impossible, given how this program's put together.

No clue. Either trivial or next to impossible.

Good question, I always wondered why Nintendo choose to hide those 8 pixels. I guess due to limitations?

That is also a decent explanation. So perhaps this was to improve performance?

 

 

Either way I'm so used to it by now, yet it would be interesting to see such an option to turn it off.

This is the oldest "NES Bug" that I've wanted to see fixed.

I think they cut off those bottom eight pixels cause you wouldn't really see them anyway with over scan on an old CRT set. I'd guess they did this because they didn't want the action being right up on the subscreen. There's an 8 pixel wide black area between where the subscreen elements start, and where the screen starts.

It's both a technical limitation as well as to improve performance. The screen resolution is what it is, so if you wanted to display those 8 rows of pixels you'd have to eat into what is at the top of the screen, aka, the HUD. But also, the more simplistic stuff you have to render, the faster you can render. I don't think it's that far out of the window to suggest that lot of the parts of the HUD is drawn in a very simplistic manner, probably not even using tile data. (Aka, fill everything here with X colour). And then overlaying the HUD elements on a second pass through.

It would be a good idea to have an NES fix rule that removes the 8-pixel cutoff at the bottom plus if the rule is set, it also removes the bottom shading in Zquest.
