Heh, I hadn't realized we didn't even have an Uta forum yet.
Today we've taken a big hurdle: ArchDemon was able to create a font that works on all required operating systems, in both Japanese and non-Japanese locales. This is very good news, because now the game will not require appLocale or any of that hassle. Basically, the game should no longer require any Japanese support to be installed on the OS.
This was really the only problem still blocking us, I'm going to compile a new Uta testbuild before I go to bed. All that's left is loose ends and RC testing, as far as I can see. We're getting very close now.
