According to http://onlynodvd.blog137.fc2.com/blog-entry-67.html the cheats there can unlock the following characters:
Licorice (Anisette.US.) Eleanor (Mrs.Varrot) Nagisa (??) Alysse Little Wing challenge (phantasy star portable 2??)
My guess is that these are tank stickers: Lapiko (??) Shining Tears (tank sticker??) Gussuma Foreigner (Alien) PuyoPuyo Sega AirRaid Jelly AirRaid Unicorn Comp. Ace Logo Comp. Aba koze Lightning King　Magari Lightning Queen　Alysse Weeks Torosute (??)
I don't run CFW so I have no idea what they are though.
? Is that a new class? Are there going to be different kinds of fencers now? Interesting. I guess Shin will be a katana wielder good against personnel while Nagisa will be a PS-style photon sword wielder which is good all-around?.
