Essentially... I want to use the castle for a (Sm4sh) mod... but I've had no luck fishing for it in my own dump. If someone could get it for me/tell me the specifics of where it is that'd be super helpful.
In order to win the bounty, you should fulfil the following requirements.
Castle model files (preferred, also with textures if possible)
Castle model files location (less preferred, must be specific)
This is just a shot in the dark but there is a logging tool from SDCafiine that reports the Wii U's file access to the computer's open cmd window. Perhaps you'll get more info by travelling to said castle and seeing what it says.
