I just went with the poor man's method. Open the google translate app, select camera mode, and just have that live translate any text that comes on the screen. if you're only ever going to play it once, why do anything else?
I've been trying to translate this game by hand for the past few days. I've made progress but it crashes when I try to start a session or if I hover the mouse over the save button. I'm about to just call it quits. Too bad because it's pretty good.
