NPA format

[Minagi]

I've finished my documentation and program for the NPA file format used in Nitro+/Nitro+CHiRAL games since late 2006. I know crass can already extract the archives but it can only do that and it's without docs. My tool allows you to extract and create NPA archives. Currently Django and Lamento Trial are not working because the formats are slightly different but I plan to support them later.

download (src): http://www.mediafire.com/?t4fz2piq52ng50a
docs: http://www.tsukuru.info/nipa/npadoc.html

usage:
General
-h - Help. Displays this information.

Extraction
-x (file) - Extract NPA archive
-g (id) - Game ID for encryption (if applicable). Defaults to ChaosHead if no encryption is entered

Creation
-c (folder) (output file) - Create archive
-z - Compress files

Examples
-x nss.npa - Extract nss.npa into the folder "nss"
-xg nss.npa MuramasaTr - Extract nss.npa into the folder "nss" using the Muramasa Trial encryption
-c nss nss.npa - Create an archive out of the folder "nss"
-cz nss nss.npa - Create a compressed archive out of the folder "nss"

(Type -h in the program to see the list of game IDs to use for decryption/encryption.)

DO NOT compress a CG folder. There is little change in size by doing so and it messes up the engine. This is a problem with the engine and Nitro+ doesn't compress their CG files because of it.

Please report any bugs. I'm also not a technical writer so let me know if there's something unclear in my documentation.

If you are having troubles with locales, try Tsukiko's modified version: https://github.com/Wilhansen/nipa/downloads

^Thanks for the update Minagi.

hello a group of friends and me are trying to make a english patch for lamento and im trying to work on the technical part and your stuff looks like it will help but your links are dead (or just not working for me)

They've deleted the stuff on purpose, so there's nothing you can do.

P.S. Ask somebody at forum in PM, there are must be some copies left.

Edit: Ahaha, my bad, Minagi. ^^' With all stuff happened at TLWiki I started to suspect everyone...

You're wrong. It wasn't deleted, I simply forgot to change the filenames in the first post.

Updated first post.

thank you!!!

Links don't work. =[

Loliserv is having issues right now it seems (I can't even access it). I don't have control over the server so the best thing I can do is tell you to give it another try in a few hours or tomorrow.

I didn't expect such a quick reply. I'll try again tomorrow, but do you think it would be possible to email the files? (That might be asking a bit much. Sorry.)

the link still doesnt work TT^TT, is it possible that you send the file to us??

For the time being, here's the 7-zipped 2009/06/30 version with source and copy of it's page. The link will expire in about 5-10 days, when I'll do the cleanup.

If it's not up by next week, I'll rehost it on my website. I can't remember if the version on my computer is newer or not (too lazy to get up and check).

[Minagi]

I've been busy the past few days so I haven't had much of a chance to rehost everything.

The links in the first post have been changed. The new directory for nipa is http://amaterasu.is.moelicious.be/nipa/.

Thanks for the update!

Thank you for this little tool, i was having trouble with crass for Demonbane, it kept extracting the files but encrypted, this little tool was very easy to use :)

Keep the good work.
