Yes, I mean, I did that already, long ago. I was just curious to ask if I needed anything else. I have the SCIM input system working, but the files are still shown as '???'. Everything else works perfectly. I haven't tried installing it yet (I've been away from home all day long yesterday), but I'll do so in a minute.
UPDATE:
Oookay, I just ran the installation via Wine and the display I get in the windows is the same as in a non-Japanese locale Windows (that is, broken fonts).
