Front Mission 1st on the DS has a beautifully snappy UI and incredibly addicting customization of wanzers. Even a bit of fashion-bots in there if you want to make all your team members have their own style. What a great game. 2089 looks like a continuation and upgrade of these strong points, so...
Hi! If you hook me up with the github I could potentially help. I'm not a Japanese master, but I have done localization code for software and can compare translations I've seen before.
