Ok, that was quicker than I expected.
Updated le-crap to version 0.2.0. Now supports all in-game dialogue (in the demo). Be warned, I wasn't able to get a second opinion for this release. Please post how well it worked on here. Oh, and be sure that your game is up to date (Version 0.02b), otherwise it DEFINITELY won't work.
Next up I'm going to work on supporting patching for the other text-based translations (spell cards, some menu options, etc.).
