The Aeon Genesis translation is official though. Pixel himself even helped with and approved it directly. It says so in the readme:

Special Thanks to...
--Shih Tzu, for facilitating contact with Pixel himself
--Pixel himself, for creating the game, allowing us to produce an
English version of it, and for putting up with what must have
seemed an awful amount of nagging questions on my part :) You've
got the patience of a saint, and this wouldn't be done without
you!
--sandcrab, who produced an alternate translation of the text for
Pixel. It is, as yet, unpublished.
--Tomato & Bugcatcher, for helping out on a couple tough bits in
the text. Cheers!
I voted the biggest "Yes" I could vote. This is the TAS I've been waiting for, and it's beautiful.
By the way, I watched what you called the "temporary encode", and it looks/sounds perfect. This TAS definitely deserves 50 fps and a good video player with nearest-neighbor scaling (or better, pixellate (like maister's Cg pixellate shader), but I still haven't found a video player that can do that).
