(Definitely not an April Fools Day prank.)
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.
