Oops....I just looked and my game is CVX. I thought it was just RECV. Whats the difference?

*Edit* I've never played RECV....well, i thought the game i had was that one, but its not. So, i dunno if there's any difference. On RE2: dual shock version, do you always start out with the machine gun and unlimited ammo on the arrange game? My brother didnt know if that was just a glitch from using a game shark too much. lol
