For those that are interested, the good people at bombermanboard.net have managed to be able to host their own unofficial bomberman online server.
For those that haven't kept up with this:
If I remember correctly, it's still in beta release in Japan. It has VERY slowly progressed as not everything is still a feature yet. It used to be an open beta back in 2002/2003 where everyone from the world could play it.
But now hudson just made it so people with only a japanese version of windows could play which made us non-japanese windows owners unable to play this game.
I only recently got wind of this and it's going well in my opinion. There is still a few bugs like characters not showing up (specifically avatar wise, not your in game character), not keeping track of points earned when winning, (I just lost all mine for some reason).
I would highly advise dial up users to stay the hell away though. You skip all over everyone else's screen.
