This version of Penta Dragon is likely a fan translation, offering an English language experience for an originally Japanese-only title. The use of "[En by HTI v1.0]" indicates the translation's origin and version, making it a valuable resource for English-speaking gamers who may not have access to the original Japanese release.  The translation likely did not affect the gameplay itself, but it significantly expanded access to the game.  Additional context is needed regarding the translator group, HTI, and its other projects for a fuller appreciation of this specific title's history.
