Included in the archive is a DW patch and a DQ patch. The DW patch changes the names to adhere to the old Dragon Warrior NES games, while the names in the DQ patch are closer to the original Japanese (NOT the more recent Dragon Quest English releases, as this patch pre-dates those).

There’s (reportedly) some untranslated text in Dragon Warrior 1. If you rescue the princess and don’t bring her to the king, when you defeat the last boss and go back to the king, there will be different ending dialogue that was left untranslated.
