MLB Baseball 2005- It wont play

I downloaded MLB 2005, but it wouldnt play. I didnt have a CCD file on it. What's going on with this game? It wont work.

What are you playing it on? Emulator or console? If emulator, chances are it's not compatible as it is a PS2 game.

I downloaded the PS1 version of MLB 2005.
