HD Texture Pack Full Guide
➜ Dolphin - https://dolphin-emu.org
Yo! I was recently asked how to install Custom Texture packs on Dolphin and im also going to show they are done via Resource Pack manager. There are already some other tutorials about the subject but those tend to be outdated with older versions of Dolphin Emu and also nobody talks about the Resource Pack manager.

You can find other basic tutorials how to setup Dolphin, in case your very new to it. In order to find textures the best place to search is the Dolphin Forum https://forums.dolphin-emu.org/Forum-custom-texture-projects
For Obvious reasons i will not link any ISO downloading sites here, you can google up and you can find couple of decent alternatives for that.
I recommend going to forums to find fixes in first place, they can likely answer faster than i can to your questions. But ill try to help best to my ability of course in comments.
