Hacking How to put DSTwo in original DS resolution?

[Pluupy]

When I play the DSTwo on my 3DS XL, the image of DS games are extremely stretched and blurred.
While they are playable, I would like to see the DSTwo games and UI in original DS resolution.
(it's also a nuisance since I am trying to make DSTwo skins as well)

So how would I go about putting the DSTwo games and UI into original DS resolution?

Hold start and select while booting the Alex rider icon from the main menu.

Nintendo should make this a menu option , and leave the start+ select to be able to quickly use the other option if needed.
