I'm using the latest patch (~2 hours ago) and I've found one thing so far where the Romaji's translation is obvious - "Ribatichiketto" is "Liberty Ticket". It's the item that allows you to take the boat to the island (from the item description, the location name looks like "Liberty Garden") and get Victini. For the description, this seems close to me: "A ticket to go to Liberty Garden. The ferry is in Hiun City."
Edit: Also, "Raibukyasutaa" is "Livecaster". It's the gadget that lets you talk to the Professor and your rivals. No guess on the description.
Edit: At game startup, "Are you sure you want to disable the C-Gear?" has an bad line break - I don't know what the code is, but it's displaying "/xfff". (Whoops, that's apparently a known issue. My bad.)
