Some1CP stopped by our forums to release a full tutorial on how to “undub” Persona 4 Golden on PS Vita. This is something that’s now doable thanks to the HENkaku hack and Major_Tom‘s recent explanations on how to mod PS Vita games.
Based on this information, Some1CP acquired the Japanese audio files from the Japanese version of Persona 4, and replaced the English audio from the US game.
To showcase the work, Some1CP released a cool video (see below. Also, rickroll included… is that going to be a thing? I’d like it to not become a thing. Please?) and a tutorial on how to do this yourself. The technique, of course, could probably be applied to other games.
The Henkaku devs for providing a new way to run homebrew.
@RyanShrinefox (for the tips on compression and battle voices).
Note: this technique of course requires you to own a legit copy of Persona 4 Golden on your PS Vita. And bear in mind that you’re still technically doing some sort of copyright infringement by using the resources of the JP games in a way that the publisher did not allow (in particular if you don’t own the Japanese version of the game. To be on a “Safer” legal side you’d really need to own both versions of the games but even that in theory does not allow you to mix the assets…)
