Hey I have a wii that I hacked over a year ago using Indiana pwns which at the time had all the up to date stuff on it, the only thing I have updated on it is USB loader GX and that's only coz it can do it online so no messing about with files and sd cards. My question is why do all the games work?
If you want, I can suggest some things that will screw it up.
But seriously...Sangor already explained the most important parts. I'd like to add a couple, though:
6. wrong assumptions. The majority of people who post issues* are also the ones thinking they know what they're doing. They think their firmware matters because it does on other consoles. Or they assume that it's better to remove a hack and start again if it's faulty.
7. ignorance. Those very people who have issues barely know what a cIOS is or what it does. Most of them know little more than that they're using "cIOS249" (version? base IOS? They don't know). They're almost proud that they're noobs and want to learn AS LITTLE AS POSSIBLE about hacking whatsoever. I've had a few pb's of people that "asked for help". And that's between brackets because after a few rounds of giving advice, I started to get the feeling they wanted me to be responsible for hacking their wii.
EDIT: less than a day later, and someone gives
a perfect example of what I mean.
8. distorted vision. this is a forum. The far majority of threads are started by people who have problems or want to ask something. That way, it may seem like there are way more issues than there really are, because the ones who don't have problems don't have any reason to make threads about it. I think your first reply on this thread reflects that: we're SO used to people making threads about problems that we're automatically assume it goes for everyone. I bet that if I make a thread in this section that I have financial problems, people will still tell me to use modmii to fix it.
And to answer your question: nope. No different models. under the hood, wiis are for the most part the same. cIOS'es are region free. Firmware matters very little. The color not at all (even that slim model apparently hacks the very same way). And the differences in region are also so slim they're pretty much ignorable.
*not all of them, though.
