No, I didn't bother. Roger's line went it which is all I wanted to affirm so I know it works. Of course I'd have to find the bubbles that show up, which are in sub, and change those to the dub line... but...
The very next part with Luffy in the bar was sub which is where I said wtf the story isnt dubbed?
Then theres no point in dubbing the game then...
Shame cause id prefer to do the psp version over the 3ds. I hate 2 screens... and PSP is much easier to mod for over 3ds which has trash ass confusing tools.
