I've seen lots of warnings come by when using the software to install homebrew and priloader etc about Gamecube controllers and memcards.
I just found out just now that i can plug in 4 GC controllers to my wii... (yes i'm a newbie) So i want to use them for some games, just try them;)
However, i want to know if there is any risk in using them with USBloader or any other 3rd party software. And what about the memory cards?
Thanks in advance;)
No harm in using them. The warnings are for specific apps that may fail to work if the controllers or card are in there. They won't break anything, just stop things from working while they are plugged in.
