Homebrew Unpacking NARC Files?

[Shubshub]

How do I Unpack The NARC Files
I have tried using narctool except it keeps giving me errors
You know the error where it says it Encountered and Unexpected error

Is there any other tool I can use to Unpack NARC file's so that I can edit them with the BW Trainer Editor?
Please

As far as I know, you can use NitroExplorer for this http://filetrip.net/nds-downloads/utilities/download-nitroexplorer-2b-2b-f6546.html

Please correct me if I'm wrong.

AFAIK NitroExplorer only supports ROMs, not NARCs.
You could use NSMB Editor: http://nsmbhd.net/download/
Just open the ROM, then open the NARC, and you can import/export files from it. Easy.
