This is a fan-made port of an official English translation into the JP version (the English release requires 3.61, so no hope to get it working). All credits to guys from /hbg/ and Reddit (https://www.reddit.com/r/VitaPiracy/comments/5auxxi/pcsb01019pcsg00891_root_letter_en_2332zex/?st=iv7pvqd5&sh=91575c3a). I've applied all the additional patches and tested it, the game works fine with some minor issues and very few untranslated lines. This version works on the Henkaku R6. Didn't like the game so far, though. The game also flopped in Japan and got very bad reception from the players, I hope it won't affect Kadokawa's plans to release more games in the series.
