Ended up buying a USB Gecko that a guy from Poland made from scratch over on Reddit. Only charged me $50 for it too. Only thing was I had to get a Mini USB cord for it myself, but I just dug up one I found around the house and it worked. Can confirm it works for Wii games using Gecko OS.
Unfortunately, my Wii can't hook Gamecube games unless they're in Wii Mode, even after getting a White Wii, so I'll be getting a Gamecube to test it on Gamecube games. I can already confirm the USB Gecko works on Nintendont with Gamecube games, so I don't see why this won't work on Gamecube. Anyways, I've attached some pictures of the Gecko below. I'm pretty happy with what I got!
