@team fail did you try installing it w/o any ext.usb or gc stuff hooked up? I know this may seem unnecessary but i've experienced problems with having a ext.usb hookup when installing WAD files and I've read from other forums about unplugging your gc controllers, memory cards, etc...
Just a little something to try out.
I often find it easier to use crazy intro to load into my usb loaders or various games even, also for the wifey who can be sometimes computer illiterate this becomes extremely easy for her. It's not hard to setup & there are many people who could provide answers im sure of, even I may be able to help you if you decide to pm me.
@pplucky thanks for the info im going to try this out in a few
see how it works.
