Snowblind's Ikaruga Texture Pack

Snowblind’s pack replaces the textures of Ikaruga, Treasure’s vertically scrolling shooter, with versions at four times the original resolution.

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/GIK/ folder.
3. Open Graphics > Advanced and tick Load Custom Textures. Ticking Prefetch Custom Textures too stops stutter, if you have the RAM for it.
