Wii U Ripping Catch-All Thread

[AlistairRoo]

So the Mario tennis ultra smash model I have has textures that dont work in them.. except for like 5 but they are kinda messed up from what I saw ..so I ws just wondering do I need an updated texture converter
or
did I do something wrong

It'd be more helpful if you provided the character's name of said model so they can see if there's something wrong with the model itself or if you did something wrong.
