You're joking right?
Hey while you're at it I can give all you guys the links to my new XBox emu that emulates all Xbox games! EVEN THE ONES THAT HAVEN'T COME OUT YET! Isn't that amazing? Ya, it is because no such thing can exist. Hell, n64 emulation hasn't even reached miracle status, how can people be expecting ps2 emulation to begin? (And Dreamcast emulation isn't very close to being done either )
ps2 emulation is a possibility in the near future, but until the pc can handle everything the ps2 does, it will be pointless. There are probably emulators, but they are useless because they cant run any games properly.
The reason why other emulators arent having as much progress as playstation is because nobody gives a damn, its that simple...
