I hope I'm the first one to announce this, a couple of weeks ago Linux (and MAC) users, got a new stable version of wine (1.6), and today I'm proud to announce that It IS finally possible to RUN Dragon Ball Online on LINUX (and possibly on Mac), I don't know if you can update it (the game) like on windows but when I run it from a shared disk (I use two OS(s) on my laptop Linux Mint 14 and Windows 7, and DBO is installed on Windows and that's where I updated it last time), to run the game you need to download Wine 1.6 and simply run the game (you can either run it by the DBOLauncher.exe or dbo.exe, both work), if you have installed Wine 1.6 and the game still does not work you might need to enter wine configuration (or whatever it's called in your language), choose windows xp as the windows version (windows 2000 is set by default), and if that won't help you might need to add some directx libraries to wine, how to do that you can learn from google.
I hope I made your day if you have some questions ask and I'll try to help

And as proof here are some pics
Have Fun

Still have a problem with running dbo with wine. I can start and play dbo without problems, if there wasn't that one detail, all my characters don't have heads. I can still see the scouter flying in mid air, but the heads are missing. I already tried to install directx libraries, but it is still not working. I use Xubuntu 13.04 with wine 1.6. I already tried wine 1.7, game starts like in 1.6, but I still have that head problem. Did you encounter something similar the first time you tried to run dbo?

I thought topic is about DBO EU.
Dream... dream... dreeeeaaaam.

No, I did not encounter such an error, did you install the game through wine? I'm using a copy installed under windows on a shared drive space and it works well with just minor light problems when playing on linux mint (which like xubuntu is a fork of ubuntu).

A guide on how to get it?

Get what? the game?

Yes on mac

First you need to download and install Wine 1.6 http://wiki.winehq.org/MacOSX , after installing and configuring wine download the DBO client installer from the web and install it like any other program or game on windows. I'm not 100% sure if it will work but if it works on Linux it should run on Mac OS X (because it's based on linux).
