Bug on Exceed II

Bug on Exceed II In Exceed II era, in order to release Solitary II, a player needed to input hidden command. And also, there was another hidden step, Canon D Nightmare(D22). In order to release it, a player needed to clear A 'Wax - I'll give you all my love -' on 3 stage. However, you can release it easily. If you lock 'Banya - Hate' on service screen (I don't know exact name.), and then input Solitary II hidden command, Canon D Nightmare was released.
