Matteoki's Wii Sports Texture Pack

Matteoki’s Wii Sports pack replaces 2,068 textures, 1,498 of them mipmaps. It took about a month and roughly 100 hours of work.

Matteoki made it as part of Game Restorers, a group that works together on HD texture packs and teaches others how to make them.

How to set it up

1. In Dolphin, open File > Open User Folder, then go into Load/Textures/.
2. Extract the download there, so you end up with a Load/Textures/RSP/ folder.
3. Open Graphics > Advanced and tick Load Custom Textures. Ticking Prefetch Custom Textures too stops stutter, if you have the RAM for it.
