Luckily cc3dsfs has a customizable spacer option that allows us to set the value to whatever we need! Now we just have to know what the correct value is.
From what I know, all we can do to figure this out as of now is to eyeball it, although sprite-based games make it easier. I went through my Personal DS Cart collection below and classified each game into 1 of 6 categories: Don't Use, Might Use, Uses, Book Orientation, and Uses + Book Orientation.
NOTE: I live in the US so these are all North American titles. I say this because some games (mainly the anime ones) have different titles in different parts of the world. Also there's no lists for DSiWare stuff yet but I will add it once we get values for some that are confirmed to need it.
Values are Determined with these settings:
Crop Settings > Native DS
Separator Settings > Multiplier: Scaling
Does Not Use Negative Space Gimmick
The following games don't use the gimmick what-so-ever, so you can leave the space at whatever value you want.

Potentially Uses Negative Space Gimmick
These have been checked and MAY use the Gimmick but it's too hard to tell at a cursory glance. Keep in mind, some games just transfer an image between the 2 screens WITHOUT accounting for the "Negative Space," or use 2 separate but similar images on both screens, so this is where this confusion can come from.
*From the Abyss (Intro Cutscene but the images seem completely separate)
*The 4 Chapter DSiWare Annoyomous Notes series is a cut up version of this game, so if a value for it is found it'll affect those as well.
Golden Sun: Dark Dawn (Some Menus but the images seem completely separate)
Mystery Case Files: MillionHeir (Might, gonna do a playthrough soon so we will see.)
Pokémon Diamond (Intro + When entering Underground)
Pokémon Platinum (Intro + When entering Underground)
Uses Negative Space Gimmick
Bleach: The Blade of Fate (Certain cutscene backgrounds)
Bleach: Dark Souls (Certain cutscene backgrounds)

DJ Star (I think it uses it on a single screen during Avatar Customization)
Elite Beat Agents (Multiple places)
Fire Emblem: Shadow Dragon (Intro)
Kirby: Super Star Ultra (Intro and Menus)
The Legend of Zelda: Phantom Hourglass (Intro)
The Legend of Zelda: Spirit Tracks (Intro)
Mario and Sonic at the Olympic Winter Games (Some Mini-games)

Metroid Prime Hunters (Menu Backgrounds + Some Cutscenes)
Naruto Shippuden: Ninja Destiny 2 (Title Screen)
New Super Mario Bros. (Minigames)
Paws & Claws: Marine Rescue (Title Screen)
Spanish for Everyone! (Title Screen)
Super Mario 64 DS (Minigames)
Book Orientation
These games use the DS in it's "Book" Orientation. This is when you hold the DS on it's side, usually with the top screen to the left. This doesn't have anything to do with the spacer necessarily, but we need a list of separate titles because...
*BookWorm
*Has a DSiWare version
Uses Negative Space Gimmick + Book Orientation
...some games that use "Book Orientation" also use the negative space trick. This seems pretty rare but it needs it's own Category regardless.
*Brain Age (When you Zoom into Sudoku Cells it swaps to the other screen)
*If I remember correctly this game got split up into the Express DSiWare titles, so again the correct value may affect those.

Obviously the DS library is massive, so I wanted to make this post as a place for us to work together to catalog correct spacer values for each game.
To Pitch your value, you need to have recorded gameplay of the gimmick in action to prove the value is correct. You don't have to be Dead-On, but try to narrow the value down to 3 potential numbers. This is so other people can take a look, the more people looking at a problem the more likely we are to solve it.
I'm gonna try and hit all the stuff I own, so I would appreciate it if people branch out and do other games.
A few tips for figuring out spacer values:
-Sprite based games are the easiest, so do those first. Sonic Rush was the first one I ever figured out because of this.
-If you get a value for one game, you may be able to get others. Keep these things in mind
- Is it a game with Sequels on DS?
Did the same dev team make other games for DS?
Does the game have a DSiWare version?
Also, feel free to check my own work. I'm pretty sure Pokémon Black and Black 2 don't use this gimmick anywhere, but it's also been 10 years since I played those games. But whatever we find out is likely gonna affect White and White 2 so...
That should be everything! I will update this post with New Values as we discover them, and link to the reply containing the footage for each game. Thank You for any and all help!
