[PS Vita] Persona 4 Dancing All Night (Undub) [Decrypted]
I have the undub version right here. Installing this should be undubbed.
If you already installed my previous regular upload and don't want to lose your save, there is a way to make it undubbed fairly easily. This reddit comment helped me convert my existing english copy on my system to being undubbed:
"For those who already downloaded the normal version (not undubed), just copy the vita.cpk file to your app/gameid/data folder."
On my Vita, the "gameid" folder shows up as "PCSE00764", so it should be similar on your Vita. Just replacing the vita.cpk file turns your existing english dialogue game into the undubbed version. Feel free to comment if you need help.
