Confusion about 480P on NGC version RESIDENT EVIL 4

[junjunleon]

Hi,

Recently I have been thinking a question.
As we know, NGC version RESIDENT EVIL 4 is 480P with false 16:9 display.

Here I wonder this 480P means
1. the whole game display?
2. the actual displaying part, i.e., the 16:9 part?

Can anyone help me out?
Thank you in advance.
