So those of you that run XP should be fine to try playing. Vista and win 7 I wouldn't bother trying. I did look up to see if you can get IPX to work on Win7 there was lots of hoops to run through and It seemed like too much bother for me atleast. Plus quite a few people replyed with the method not working.
Ok, folks who are unawares, we're gonna go with http://fonline2238.net/forum/index.php?topic=4.0 instead, for that Fallout Online experience Can't get Fallout Tactics to work in multiplayer on Vista and newer, which is a shame really..
