Patch 1.01 for Final Fantasy XIII was released today for the Japanese PS3 version (Note: Any other Asian version or English version will not receive this patch). This patch introduces “Easy Mode” which was added to the International version (Xbox360 Japanese version). Easy Mode allows you to deal more damage when an enemy enters Break (Stagger) and drop rates are increased. If you are still lacking the Platinum Trophy and own the Japanese version, now would definitely be a highly suggested time to go get it! The patch is around 48MB large.
This patch will allow you to either start a new game with your desired battle setting (Normal or Easy) or load up an old save and change it in the Configuration menu.
