A work-in-progress ROM editor for PMD: RTDX that doesn't have a proper name yet. See this thread for more details:
 

ROM Editor for Pokémon Mystery Dungeon games. Refer to the tutorial for details:
 

Pokémon sprites extracted using GfxCrunch. This 7z contains everything one needs to create animated sprites. It is not intended for humans, as sprites have not been stitched together yet.

Not 100% complete, but it's in the post game

Not quite 100%, but the story's been completed at least.

This is a text editor for Pokémon Mystery Dungeon: Explorers of Time, Darkness, and Sky.

Pokésav is a save editing tool for Generation 4 (Diamond, Pearl, Platinum, HeartGold, SoulSilver). Its development has ceased. Users are encouraged to use PKHeX instead.
Pokésav does have a few key features that distinguish it from other things, such as Underground editing; if you don't need something specific, however, stick to PKHeX for gen 4 editing.
There are different files for each game and language. Use this table to find the version you want:
  English Japanese French German Spanish Dutch Diamond/Pearl pokesav_en.zip pokesav_jp.zip pokesav_fr.zip pokesav_de.zip pokesav_sp.zip pokesav_nl.zip Platinum pokesavplat_en.zip pokesavplat_jp.zip pokesavplat_fr.zip       HeartGold/SoulSilver pokesavhgss_en.zip pokesavhgss_jp.zip         Zip file password (with the space and capitalization): Project Pokemon

This program was developed for those who wish to convert their save files offline, rather than having to go to the online one.
It uses a similar interface, and supports conversion between the following save types:
Save File Formats 
Action Replay DSi 
Action Replay Media Edition 
Action Replay MAX
Acekard 2 
Acekard RPG 
AKAIO 
EZ Flash V 
RAW Format 
CycloDS 
EGDE 
M3 Simply 
NinjaDS 
R4 
Supercard CF 
Supercard DSONE 
Supercard SD 
Top Toy DS 
M3 DS Real 
G6 DS Real 
DeSmuMe 
System Requirements:
-.Net Framwork 2.0 or 4.0
-Windows (Vista or 7 prefered, XP may or may not work)

This experimental console application can extract files from NDS ROMs.  The best part is that it's made with .Net Core and is by extension cross-platform (without needing any frameworks to be installed).  It currently cannot rebuild NDS ROMs, but ndstool should be able to accept the files this tool creates.
Usage (Windows):
ToolkitConsoleCore.exe <ROM> <OutputDirectory>
Usage (Linux):
ToolkitConsoleCore <ROM> <OutputDirectory>
Since I don't have a Mac, I can't say what the OSX usage is.
If anyone wants builds for other OS's, I can theoretically provide them if your OS is listed here.
Note: The file size being over 100MB is the result of 8 platform-specific builds being uploaded.  After you click Download, just choose the one you want and the it will only be 20MB max.
