Custom screen (1600X960) question

[LexDG]

I’d LOVE to avoid a theory war but I have a question about a POSSIBLE, theoretical, 1600x960 screen replacement.

This screen would of course perfectly scale gba, nds, and 3ds games without massive letterboxing. The QUESTION is, would this ALSO need a custom parallax layer or would the existing one function exactly the same way?

It would need a custom parallax layer, considering the size of the pixels would change if you installed a screen with a different resolution. You might get some results using the stock layer, but I would think it appears less than ideal, if it works right at all.
