Dragon Quest V(e) not boat related.

So I just finished the first gen going from kid to teen, but it freeze at the beginning of that scene. I shut off the system and started it up again and i'm beyond that scene but i can't leave the castle and if i go upstairs it freeze. I have an R4 with ttds installed. Anyone know how to continue.?

Nevermind, I found the answer off gbatemp, it seems if the bypass code is ever turned off it can send you where you don't belong.
