I hope to research how to do this at some point. I do know the rooms still exist in the english version, although no dialogue is present, which isn't much of a problem. If I can find a way to do it, I will, but as far as I'm aware, the only problem with this is the slot game itself not being in the localized versions, but through clever file swapping, maybe it'll work... I'm going to try my best to figure it out, but it'll probably take awhile if I do.
