Phantasy Star Online: Episode I & II Cheats (Xbox)

To unlock the next difficulty setting in one player mode, just beat either level on the
current difficulty level (e.g. to unlock Hard, beat it on Normal, to unlock Very Hard,
beat it on Hard, etc.).  To move up in multiplayer play, increase your player level (20
for Hard, 40 for Very Hard, and 80 for Ultimate).

To unlock the dressing room, you do not have to have beaten any quests at all, you
do not have to have cleared the game on any difficulty. All you need is have at
least 10,000 Meseta in your inventory. 

If you have 10,000 Meseta in the bank and less than 10,000 Meseta in your inventory, you
can't get to the dressing room, but if you have 10,000 meseta in your inventory, you can.

If you have 10,000 Meseta in your inventory, you can access the dressing room from the
menu that comes up when you select your character from the character select screen. You
go to "Dressing Room", and it says, "It will cost 10,000 meseta to make this change, is
this OK?" and then you select OK.

You can unlock other difficulty modes while offline, simply by clearing either episode on
Normal, Hard, and Very Hard.

If you are poisoned by a plant enemy while stuck in paralysis the paralyzing effect will
immediately disappear.
