To make Xlink kai work, you need a wireless card found in this list: http://www.teamxlink.co.uk/forum/viewtopic.php?t=11469

If not, you will need to buy a card, or by a WiFI max for your PC (about 40 US dollars) or a cheap one on this list http://www.capcom-europe.com/forum/showthread.php?t=2571 (10 US dollars)

Sorry, my bad. At the time I tred xlink, you needed to use CFW which is a BIG NO on the MH Wiki. But I reread some of the new faqs and found out that CFW is no longer needed.

Both methods are very specific, ie what os do you have. The way for installing them is slightly tedious, and if you do't know what you're doing, you may end up busting the wireless card of either the pc or the psp. There are a lot of guides in the above site, but choose wisely.

Also, please don't support piracy. If possible, buy ten copies of each game. [a bit exag, but you get my point]
