sl1nk3.s 0259cc388e Some updates to netplay, now using UDP to transmit pad data, it shouldn't be slow as molasses anymore, but may be unrealiable. Netplay now saves settings to ini, also fixed possible desync.
+cookie update : Updated Dolphin's icon to be Win7 ready by making it 32x32, so it now shows fine when alt-tabbing :p
