Wondering when Sony will launch Ad Hoc Party outside Japan? Don't get your hopes up too high. Some guys from Capcom have a couple of reasons to believe that it may not go Westside anytime soon. Since it was their game that first supported the service in Japan, they should have a good idea of what's up.

Details after the link.

Xlink Kai is "tunneling software" that allows you to connect with other console users around the world, and play online games for free. This means that you can play Ad-Hoc games over the internet with others!

How does it work? Xlink tricks your console into thinking that the other users it is connecting to over the Internet, are actually part of a Local Area Network (Ad-Hoc), and therefore allowing you to connect with and play against people from all over the world.

Xlink Kai has been around for a while now, so why am I writing about this? Well, up until now this could only be done with a few select wireless router models with custom firmware. The drivers used in the Datel's WiFi Max accessory previously weren't compatible with Xlink Kail; but a driver update has changed this. The latest 4.13 drivers from ZyDAS, the maker of the chipset used in the WiFi Max, has a special "PSP Xlink Mode" built in, and you've guessed it, WiFi Max users can now use Xlink Kai.

This not only means that the WiFi Max router is compatible with Xlink Kai, but other routers which use ZyDAS are also compatible with Kai. If you have a router with drivers made by ZyDAS (ZD1211), download the latest drivers now! You can read about how to configure the new drivers here, and how to set up Xlink Kai here.
Thanks for the tip Haaru!
