Hacking Help on CPKs

[Nikoru]

Can someone teach me to unpack/repack .cpk files
because I want to change the language of Mario & Sonic at Rio Olympic 2016
from Jap to Eng

Can someone teach me how to skip compressing the sound files because it interrupts the operation when I try to repack+compress cpk using Cri file maker

Use this QuickBMS script to extract the cpk file: https://drive.google.com/open?id=0Bxd24PdRPVF9ajFWM3VNdUVJSXc
As for the pac files: I've tried using Sonic Lost World's pacpack (modding tool) but it doesn't work with this game's pac files.
