• Af Home Use Middleware Package

Well after googling a bit I found you can download a program (FileMajik) from CRI (after registering to download the free version of their tool) and indeed the the FileMajik package (.msi) installs a tool to read the CPK file. The tool verifies that the CRI file is valid for Sigma. So I think we can safely say this IS the format of the CPK files being used today in a few DS games.

In fact, sales pages for this are available as FileMajik for the DS (The English site (allows you to download a free version of FileMajik, which includes a few library files and a broken File Packer tool. The CRI Packed File Maker tool loads Sigma's data.cpk file and shows 8651 sub-files compressed (quite a few were 0 bytes in length) within it but the filename information was stripped for space. As for extraction the packed file was intended to be treated like a file system (which doesn't need a 'Work' area in memory to decompress from) and the download contains libs (cribasepc.lib and crifilesystempc.lib) as well as an example of a C program that reads a CPK file. Which might be used to build an actually decompress/recompress tool usable for Translation. Another good site is: Download the utftab suite there. It will most likely allow you to unpack the CPK files. The outcome will be most likely AAX or ADX audio files which can be played back with invgmstream.

Welcome to the Shenmue Translation Pack. The Shenmue Translation Pack is a package composed. The CRI Middleware ADX SDK allow you to handle AHX.

Which you can get at invgmstream is a toolkit and a Winamp plugin to play audio files from various video games (including Mario Galaxy, Brawl, many Sonic games, whatever, blablabla (the list of supported formats is huge). If you have Winamp or if you're interested in using it, get it, the plugin is worth every KB of download - however you can also convert the files to.wav with the included test.exe - however, loops and such are lost then.
