Easy name change and right section ID for new characters.
NOTE:You need to be able to log online for this trick to work.
To get the section ID you want and be able to change names without a problem, create a new character and set him the way you want. For his name if you insert a letter followed by the letters periods g.o.d (all lowercase) you will get a section ID. example:P g.o.d which will give you a yellowboze. If you sign into Xbox Live with that character it will immediately give you the error about changing your name always. By using this glitch you can make any ID and be able to use a name that normally wouldn't get that ID.
A g.o.d - Bluefull, I g.o.d - Greenill, E g.o.d - Oran, M g.o.d - Pinkal... etc.

Open the Dressing Room
All you have to do to get to the Dressing Room is make sure you have at least 10 000 Meseta ON a character (NOT in the bank) when starting. A new option will appear, labelled, ''Dressing Room''.
Once in the dressing room, you can change your characters costume and hair-style, for the low low price of 10 000 Meseta (hence why you need 10 000 Meseta to open the option)
