The english ps3 version is out and the idea was using wiiscrubber to extract the main 3 .cpk files from the wii and using mamu's tools to extract/repack the 3 .cpk files.
If the tools need to be adapted to the wii it shouldnt be too dificult.The only difference is the wii is using a lower .cpk...
I sent you a pm because you're the only one who expressed interest.The spanish translation may be using these very same tools and why its now possible.
Someone has created tools for the ps3 version of this game and they have made the tools public.These tools im certain can be adpated to the wii version.
