Okay, I know that not very many people play Half-Life on the PS2, but I bought it for about $10 a while ago in order to play the co-op game with my friends. I know that you can connect a USB keyboard and mouse in order to play the singleplayer game, but does it also work for the co-op game. Also, I was wondering if there was any way to connect 2 keyboards and 2 mouses for the co-op or multiplayer using a USB hub. Thanks!
