Genius/kojiten Question, C3200/cacko/japanese

Hi!

I'm in Japan, studying a 6-month japanese course.

I just bought the Zaurus, and I know is much more powerful than a Palm (That's a reason of why I bought it).

Right now, I want to use it as a Japanese<->English dictionary, so, i DON'T want to lose all Japanese support, I just need the menus/desc translated into English.

So far, I think I have 2 options:

1) Use it as it is (my japanese is still bad, so many things I can't read)
2) Use the english translation of c3200 that was posted on zaurus-themes (or maybe trisoft).
3) Install Cacko 1.23

I'm a computer engineer, so I'm not that scared to play with linux, but, it seems that some things need to be done.

I want to use Cacko for the improvements made over oficial ROM, but, is there some advise about how to put ALL japanese support, without losing the english translation?

I know there is a "Japanese Kernel for Cacko ROM 1.23", but I don't know if that will include ALL japanese support (because the one that comes with zaurus rom is great). Also, I know is a kernel, but i suppose is different than the ROM, I don't know how to install/test it.

Thanks for the help,
Omar
