Invincible Tiger: The Legend of Han Tao

Play any level in Co-Op mode and once you complete it, the trophy will pop! You can either do this online by finding a boosting partner in the Trophy Boosting thread (extremely hard to find someone playing this title normally now) or use a second controller for the 2nd player. If you use a 2nd player and don't have anyone to use it, don't worry, just let him die off and than play normally, (but realize that when he dies you have no lives left yourself and have to buy extra lives if you die with points).
