Aigiina no Yogen - From The Legend of Balubalouk, also known as Aighina's Prophecy, has been fully translated into English. It's an arcade-style action platformer released in 1986, and thus is one of the first Famicom games to use a large amount of in-game dialogue. Up to now the only translation available only translated the in-game menu and a couple of lines of NPC dialogue: now, the introduction, password system, ending and NPC dialogue has been fully translated (and corrected, in the case of the ending).
While it's perfectly possible to complete the game without understanding the text, having it translated brings a lot to the game, and documents you can find during the game will give you clues of how to progress. That being said, it is still fiendishly difficult to figure everything out without a walkthrough. If you've never tried this piece of platform fun before, why not give it a try now?RHDN Project PageRelevant Link
