I’ve realised that the title ID of Miitopia shown on the citra page is different than the title ID I have in my computer, the game is running well, I’ve even done the entire game to the end, I’m just wondering if it was like, have the title id changed at some point ?, did I got a wrong rom ?, I was going to clear some of my savestates and noticed this somehow 
Titles on the 3DS are region locked. Meaning that Miitopia for the USA region, like on our compatibility page, has a different titleID than Miitopia for the EUR/AUS region.
