This is why we tell people not to monkey with themes. It's just not worth this! Having this conversation is unnecessary, and could be avoided. Hopefully this will serve as (ANOTHER!!!!!) lesson to anyone reading it: DONT MESS WITH THEMES.
So heres the story. Wassabi and DriveKey modchips (maybe others, modchips are all but past for me) support autoboot. Now here's the rub. You cant get to the configuration screen with your wii as it is now, so you'd need whomever you buy it from to pre-configure autoboot & region free for you, or you'd need to convince a friend to tear their wii apart so that you can configure it yourself. If I were your friend, it would be a really hard sell given that you botched your own.
I think the point there was that you're going to be spending a chunk of coin on the modchip, with no real guarantee that you'll have something working @ the end of the day. Getting a new wii @ this point on the ebays is likely in the same general vicinity.
