How would I edit cheats with my M3 DS Real?

I'm trying to do the Chrono Trigger fix, but I have no idea how to put in new cheats.
My FlashCart is a M3 DS Real, as stated in the topic.
Any help is appreciated.
Note: This is the one solution I want to try.
Don't suggest the patches, because I ALSO don't know how to do those.

R4CCE is what is recommended.

Sorry, but I don't know how to download it.
Google translate didn't help.
I can't find the download link, and I don't really trust it.
Any other program?

That should work, it's a direct link. In any other case, there should be a button at the top that says "Engrish." That is also the official site of the program.
Engrish -> Soft -> R4CCE

See my tutorial in the Tutorials seciton. Works the same way,
