He didn't? You see, the ship started to sail with SM64 but today it's this big ship of harkinian. The PC port of SM64 used https://github.com/Kenix3/libultraship already (just not with such a nice name and not under a seperate repo... With SM64 libultraship is all over the sources, you have to read deep) and, while I didn't look into it, I would bet libultraship can handle native N64 models.Does anyone know how @AboodXD managed to compile the SGI Models for Wii U?
Here's for example something for Wii U graphics in libultraship: https://github.com/Kenix3/libultraship/blob/main/src/graphic/Fast3D/gfx_wiiu.cpp
Here's a lot of resource related stuff, like texture loading: https://github.com/Kenix3/libultraship/tree/main/src/resource
... Just search your way and/or ask ship of harkinian devs how they did it. But maybe don't go to them like "hey, how to compile the models for Wii U?" but more like "I searched and searched libultraship, how is it reading the modell data into shaders and stuff the Wii U understands?".
