CHANGELOG
 Â *Added support for extracting NARCs containing folders that go 1 level deep
 Â *Temporarily removed the pack feature due to breaking the code

I have been testing this new version with the mkds course narcs and it works well. Please let me know if you come across an narc this version fails to unpack properly.
Also note that this is an upgraded version of narctool 0.1, not 0.1-p

I have also figured out the purpose of the two unknowns in the FNTB Header:
CODEtypedef struct {
ÂÂÂÂu32 id;      // "BTNF" or 0x464E5442
ÂÂÂÂu32 length;    ÂÂÂÂ// length of this section
ÂÂÂÂu32 offset;    ÂÂÂÂ// 0x00000008 If No Folders, Varies If Folders (Subtract 8 First)
ÂÂÂÂu16 extra1;           // Extra 0x0000
ÂÂÂÂu8 folders;           // Number Of Folders + 1 (for root folder)
ÂÂÂÂu8 extra2;           // Extra 0x00
} FNTBHeader;

Narc files of 0866 Puyo Puyo! 15th Anniversary doesn't unpack (these narc files don't have filenames btw). Version 0.1-p didn't work either.

pokemon diamond ppark.narc wont unpack. it throws an error.

 

[dexter0]

Yeah, both issues are because the code is based off 0.1 not 0.1p. First priority is fixing the compression routines. The pack feature is done but it can't compress the narcs into carcs properly. After that I will look into merging the 0.1-p modifications into the code so narcs from puyo puyo and pkm will extract.

I am keeping track of my progress here:

Well...Wario: Master of disguise creates an annoying noise and fails to unpack, Professor Layton and the Curious Village fails to unpack any files from any of them. It also gives a runtime error with Professor Layton, saying that the runtime requested it to terminate ina n unusual way.

I was wondering if the text in games in the narc files because i got bored about a weak ago and unpacked a bunch of games and all i could find are .narc files.

I'm using crystaltile for my narc needs but I'll use this one if it's better

Thanks dexter0.

I get the same problem with Wario: Master of Disguise as described earlier, as well as Professor Layton. And for some reason it always seems to try unpacking a million files though I doubt there's hardly that many.

Try this program: kiwi.ds' Editor

It is by far the best in performace of all the extraction programs.
