This reminds me of the fan translation projects for games like Ace Attorney from Japanese -> Korean. They also found a way to extract the game strings and put them into a google doc. It was super cool.

So I went through all of the hassle of modding my 3ds to change its language to Korean (Nintendo only allows specific languages per 3ds region), and patching a romfile of Ace Attorney. Then Nintendo released Ace Attorney 1-3 on the switch and pc, so that was great timing. It's still annoying on the switch as the game supports Korean, but only if you set your system language to Korean; hardly ideal if anyone else uses it. At least with Steam it can be configured per-game.
