Hacking G Gen World Translation!

[CrashmanX]

So I'm back again working on my SD Gundam G Generation World translation. Progress of sorts has been made. But basically after I posted here I dropped off working on the project for about year. BUT NOW I'M BACK! I've figured out how to translate a few menus and a few song titles from within the main DATAUMD.CPK file.

However, through my research I've discovered this to more or less be a giant Zip/Rar file. I can't seem to get it open up properly. I've tried using CRI Software's Filemajik among a few other programs like QuickBMS and have had no luck. I was curious if anyone else knows a program that may be able to open up CPK files or if I'm doing something entirely wrong.

Also if you have any questions don't be afraid to ask me. I'm more than willing to answer.
