I couldn't find any other post with this issue, so I posted here since the Reddit page is closed. In the opening area, there will be a missing ground texture in the Gamecube / Wii versions.
For anyone else having an issue with the ground in Pikmin being invisible, try this:
Go to Graphics > Hacks > Other > Turn Off "Fast Depth Calculation"
If that doesn't work, go in the top left corner of Dolphin, Click: Emulation > Save State > Save to Slot
This means you can leave the game to troubleshoot without loading again through the intro screen.
I hope this helped anyone else struggling with loading the first Pikmin game, and if this is the wrong place to post tips I apologize!
