What? Why?

 

Maybe it can be done but I think no one will ever see this as a priority thus what you are wishing may never be realized.

 

How I do that?

 

You can do it directly on the wii with Multi Mod Manager.

There's a button to press in the IOS manager to create a custom IOS. You want a base of IOS60 v6174, and you want to install it in IOS9's slot. The rest of the options (the new version number, patches, etc.) are your choice.

 

Done, will try, my lens is kinda screwed, with luck I could load Twilight =P
Thanks!

 

This isn't new, original, or interesting... If anyone ever installed cioscorps or darkcorps they already basically had this.

Also there is absolutely no reason to run any ios as ios9. Ios9 is primitive and only works on one game.

 

I had done this and it is pretty awesome-ish

It slightly improves the crappy Wii.

 

But as it is POINTLESS to be on a lower System Menu than 4.1, that is fairly irrelevant. I'm more interested in if it is possible to get SDHC support in games by switching IOS around...for the few games that support loading stuff direct from SD.

 

This.

Still, if the calls have the same interface as the regular IOS, I can't see why is should not work. The chance that this is the case is just about 1%.

 

Figured it wouldn't be that simple, or Ninty would just add SDHC support to an updated revision of the older IOS I guess.
