Surgy did a translation of the newer 3.x engine of WolfRPG Editor (the game no longer loads with the older editors). The post is here on F95zone at:

It's a bit of a learning curve to use, but here's some tips: To find the starting text, etc, click 'view', 'map selection', then click on map '1', then double click any 'Ev' box to open the events on the map. The starting questions are in '00:ニューゲーム処理', the first event. With ctl+F you can find strings of text using the original JP text from Translator++ to locate text much faster to swap out (careful, doesn't search backwards, so start search at beginning).
