A113?  Also I was playing on Standard.  Btw, to unlock the Secret Ending you have to get a certain number of Lucky Emblems.  I don't know how many you need in each difficulty, but Beginner you need to get all 90, while for Standard I got it with 66.  Next I'm going for Ultima Weapon, as well as getting all treasures and Lucky Emblems in the Carribian and San Fransokyo
