HOLY MOLY
So I figured out the issue. My Wii's date was set to Dec 31, 2035. And Apparently, the Wii, and for whatever reason only the USB Loader, can't read GC Input anymore. No Idea why this is the case. But I found out about it from this smash boards thread.

I while I was case modding I took out the internal battery, and I also powered on the case while the internal battery was removed which caused the weird timing errors.
Hopefully other people who come across this issue will be able to fix it as well.
