The book was originally published in Japan. In 2008, Udon Entertainment published an English-language version as ISBN 978-1897376027, retaining the original right-to-left format. Udon's English translations in the book are not always consistent with Capcom's English localizations of the game, but since both of them are ultimately based on the original Japanese version of the game, neither Udon nor Capcom is necessarily more "correct" than the other.
