Extracting/Unpacking .NFP files from NDS Roms?

[aidhus]

Anyone had ever extracted or unpacked a .NFP file from a NDS Rom before? I am trying to rip sprites from a game called Hayate no Gotoku! Boku ga Romeo de Romeo ga Boku de?

Your help is appreciated! Thanks in advance!

There has been some talk about the format on GBAtemp here and here, but I don't think it's been completely cracked nor has there been a program made for it (that I can find anyway).

All I can suggest right now is to upload a sample file (maybe two or three), I can take a look and see if anything can be done.
