How do I bypass the preloader screen?

If your WiiMotes are not synched anymore, you can manually resynch them. There's a button next to the batteries in the WiiMote and another one next to the SD in under the cover on the DS. Press them both at the same time and the controllers will resynch.

 

Does your wii go straight to preloader without pressing reset?

 

When you ReSync the wiimotes to skip the preloader menu when you press start you have to set:

autoboot: systemmenu

and if you wish to return to your system menu when you press home->wii menu you have to set

return to systemmenu

 

gamecube controller go down to settings then autoboot systemmenu worked for me a couple months ago

 

Menage for example i couldn't use my GC pad, only the wiimote.

However, it's a strange problem and it's the first time i had ever heard about. Did you tried to change batteries? When the level is red in the wiimenu the wiimote can't resync, nor manually. Try a new battery pack and manual resync.

Moreover, when you push a button on your wiimote does the blue lights light?

(sorry for bad english LoL)

 

I've had this problem earlier today, I fixed it too. You have to open your Wii, all the way to the mother board. Then re-seat your BT module. I did it even without a tri-wing screwdriver. Either that or your BT module is broken. Maybe your Wii fell? Mine did. But anyway this isn't a preloader problem.

 

Get a cheap GC pad?

I'd prefer doing that to needlessly opening my Wii.

 

That's the reason I added rescue exit to System Menu with reset button to "Crazy Intro"...
Since I have two wiis, I often have this problem.. I had to use my gc controller to boot system menu... Afaik that was the only solution so far
