Command and Conquer Red Alert PSX

Apologies if this is in the wrong threadI downloaded the PSX version of Command and Conquer Red Alert Soviet Disk for the PSX. When the download was completed I started up the game to discover it was the 'Red Alert : Retaliation' Sequel. I have not yet seen if the Red Alert : Retaliation PSX download will give me the vanilla Red Alert but i think this may be a case of mismatched titles.
