FFV Battle Windows

Using the first method worked, but at the same time, made me realize that the extra row is likely drawn for the purposes of the heat wave and underwater effects in deserts and the submerged Walse Tower, respectively, and possibly for other battle backgrounds that do something similar, since the effect is now more noticeable at the bottom of the two mentioned backgrounds.

So now the question is, why does the top row of pixels from the bg get drawn above the top row of pixels for the menu windows? I checked again, and noticed that the entirety of the battle scene, including the menu windows, seems to be drawn one pixel higher than it should be drawn on the screen in-game when compared to the actual tilemap being loaded into vram. So maybe that's why? Because the whole thing is seemingly misaligned vertically by a row of pixels?
