Mass Effect 1 PS3 .pdf manual references XBox controller buttons

There's an in-game manual in ME1 that covers different aspects of the game. It might help but I don't remember if there was a specific controls section when I last played it. You can access it from the Extras section on the main menu or from the pause menu during the game. EA should fix the online manual as well though, no reason not to have a working online manual like the other platforms.
