So, to submit to this leaderboard, we need exactly two things:

 - a way to accurately re-time your run, if needed
 - a way to verify your run

Due to the nature of 3DS speedrunning, this isn't quite as simple as plugging into a capture card and going, so here are your options.

1. Emulator - Citra

Citra is allowed on its own leaderboard due to having fairly high accuracy for Cave Story 3D. Load times are drastically faster so it cannot be on the same leaderboard, and we've opted to allow turbo should Citra ever add it. Feel free to just run to your heart's content on emulator.

2.1. Hardware - Timing - A Line-In Cable is REQUIRED.

So, besides a hardware capture card which are exceedingly rare now, there isn't a particularly easy way to capture the game at a steady framerate. This means that you will need to have a way of directly capturing audio from the 3DS, which is as simple as a cheap $5 line-in cable. If there's some other way to record audio, that is fine, but some form of direct feed audio is required for all submissions.

2.2. Hardware - Verification - the NTR "problem"

So, after some testing, it seems that NTR does not significantly speed up load times. Thus, the following methods of recording 3DS video output are allowed (and just ask if there's something missing from this list)
 - NTR
 - HzMod
 - a hardware capture card
 - a webcam pointed at your 3DS, so long as we can tell what is going on
Honestly accessibility is most important on a system that is quite difficult to capture for. NTR/HzMod must be noted as being used for your submission, but this does not remove it at all.

2.3. The installed vs legit cart issue

It's as simple as there's no way to enforce this reasonably. You may use an installed version of the game despite CS3D having never been released digitally.
