DDR X PS2 - Wrong Code

You thought this game was over with. Well, guess what? The code you guys think is correct for unlocking characters is INCORRECT!
Yes. I have proof. In words.

You say to "Unlock SN characters, play all Advanced missions and to unlock SN2, play all Basic". Well, Here's my story

I played my game without a memory card one day. I tried to unlock the characters that way. Well, I got them...

Then I reset it and played the Basics first. Still got the SN1 character costumes.

Now, I unlocked my characters a different way. Here is the CORRECT WAY TO UNLOCK THE CHARACTERS:

X Costumes: Play Mission 1 of certain person's story
SN1 Costumes: Play the Final Mission of certain person's story
SN2 JP Costumes: 100% certain person's story

Don't believe me? Try it for yourself.

(BTW: I couldn't find the DDR X PS2 USA in the forums, even with the search. And, I also didn't know if it was still a sticky or not.)

Yeah,I was kind of confused when I finished someone's story in JP CS and got the SN1 costume finishing all the missions in Advanced.
