How to Play the Uta no Prince-Sama Games in English!!
Disclaimer!! This method won't provide a completely accurate translation but after playing one route fully (around 8 hours), I can confirm that this method works well enough. You can understand the plot and even play the minigames (I recommend playing them on easy though since they can be quite challenging on hard)
This method also works on the official releases of the games so pirating or emulation isn't necessary. Obviously I can't stop anyone from pirating but if you can please consider buying a copy of the game. At the time of writing all of the games are on sale on the Nintendo eShop, with Repeat being 50% off and the rest of the games being 20% off. Just make sure to test this method before spending any money, I don't want anyone to spend the money and then realize this method is uncomfortable or anything of the sort.
