I hope this helps someone!Īt the time of writing this, only the Mupen64Plus core allows the use of HD texture packs (ParaLLel N64 does not).
It may seem like a lot, but once setup, it's quite a quick process. So I decided to write up this guide, I apologize for how long it is, but I wanted to be as detailed and as clear as possible. I spent an entire day trying to figure out how to do this, banging my head against my desk, and getting frustratingly vague answers/result from countless google searches.
