CAK files and how to convert them?


Staff member
I know if I rename the Saturn CAK files to CPK I can convert them to avi's just fine, but without sound. What I want to know is any clue what the sound files might be disguised as and/or how to mix them with the video so a whole video can be shown?

If I can do this that will mean alot more movies on the movie section.
A CAK is a CPK with ADX compressed audio. (Catch that? That's too many abbreviations for one sentence) I know that you could *maybe* convert them to avi, rip out the audio portion (with VirtualDub or something) and use adx2wav to convert the audio and reinsert it with a video editor... I'm just speculating here though, email me ( and I will help you figure something out, for sure.
There is a utility out there that will properly convert cak files to avi with sound. It's a japanese program but there is an english version of it. In case you want to search for it, it's named cinepack.exe (Japanese) or adxplay.exe (English). I also have it on my computer, so let me know if you're interested.
