Hi All, I've eventually got two gamecubes, both unchipped, one UK and one USA. I've got broadband adaptors in both but cannot for the life of me get Mario Kart to link up, I've removed my router and tried a crossover cable also to no avail, Both GC's get to the "Looking for gamecube systems" and both time out after the 150 second wait. When both are connected to my hub link light lights up so I "know" the broadband adaptors are "probably" good. I set the UK one to 60Hz as this can cause a problem if both are at different Hz. Is there any PC software I can install to see which one is "failing". Can I identify the traffic with WireShark on a PC, if so how do I identify it? How do GC's know another IP is a gamecube? Any help much appreciated!
