I can't start until I've seen the end

[Wisemon]

After nearly three years and a change of batteries, I finally beat my D-Tector game. I have the blue and yellow version, which for some reason, was only sold in America. Actually, I have two of them. According to the game sites, beating the game was supposed to unlock Kouichi, but it didn't. Also, none of the ancient warrior codes worked. It's possible that these changes were only made in the unified evolution D-Tectors. Can anybody with either a Takuya (red and gold) or Kouji (blue and black) unified D-Tector tell me if the ancient warrior codes work? If they do, I'll go to Toys 'R Us and buy Kouji's.
