Dissidia: Final Fantasy - Serial Codes

So I purchased Dissidia Final Fantasy for my PSP on the weekend and got a 2 serial numbers to register on Square Enix, the membership section is currently offline so I have no idea what this code does, but once it's back on I'll redeem one and post what the other does.

Depending on what it is, all I'll ask for is like 50 cents, or free if it's something shitty will come back and edit later what this thing does.

edit: all you get is 50 Square Enix points.. so if anybody will actually use this I'll give it away for free I guess
