Screw ATLUS for their crappy dubs, no dual audio, overpriced 3DS releases and awful treatment of European fans.
This my first 3DS Undub.
You need Gateway or a 3DS with 4.5 CFW in which case you'll have to convert the rom to CIA yourself.
The Undub comes in two variants:
Variant 1: Japanese audio, but English movies (good for first time players)
Variant 2: Japanese audio and Japanese movies (recommended for people who are replaying the game)
The reason for it is that the movies are hardsubbed, similar to how Funimation streams their anime.
Japanese movies have kanji subs hardsubbed into them, Englishb ones have english text hardsubbed.
Should 3DS movie format be reverse engineered in the future, then I'll make a 1.0 version of the undub.
It'll be using English movies but audio from the Japanese movies, remuxed together.
For now it's impossible due to the moflex video format used by some 3DS applications and games (SMT4 is one of them).
If there's any developer willing to reverse engineer 3DS's .moflex video format, I'd very much appreciate it.
