+Rep for doing this. It's always nice when Capcom does this for their games(like the Lost Planet T-Shirts search )

Codes? are these put in when you are in the game? or are these actual codes and there is a normal way to obtain them?

Thank you so much.

lvl 7 Gouki is Akuma in the english version. (people may get confused)

And all the codes work perfectly.

Sweet, thanks for the language fix, updating the original post.
Also thanks for confirming they all work.
