I don't see why these companies refuse to use a GGPO style of netcode. There's no excuse for the netcode to be this unplayable when the technology is out there to reduce input delay to virtually nothing.
Third Strike online uses GGPO and Honestly I could say that the netcode is worse than the one used in XIII, at least from my experience
People should realize that netcodes are not some sort of magic device that will run everything fine, the netcode used to run 95 on psn will not necessarily run well in XIII, and so and on, even from experience, the only flawless netcode is the one used in BB, and still I'm sure that is not as perfect as how some people could describe, at least from a more hardcore perspective, at least I thought that a yellow bar connection in SF IV was good, but after a while learning better the game I realized that there was a semi notorious lag
At least, SF IV and BB netcodes are miles better than XIII, which IMO really sucks, and still don't know how much the update could help, at least I think that the game should be playable in yellow bars when the not so hardcore players don't realize that there is some flaws, but at least for KOF I don't think that there will never be a netcode that could handle well the most complicated stuff (98 runs fine for me, 2002 in ggpo runs good as well, but not exactly perfect) at least I think that is bad to follow a game for his netcode since never will give the full experience, but still understand that at this age is necesary to give a large life span to some of the players with no access to other guys, but it will not help to gro a wcommunity necesarily (BB netcode is flawless but the game is not at full power at this moment, MVC3 netcode completely sucks but the game is doing well community wise)
