Since the forums & youtube have been flooded with different methods, i will explain how i got mine to work.
[Wii Latest Version 3.2e - TV MUST SUPPORT 60hz (480i/p)]
Boot Method 1 - Insert freeloader disc, eject & insert import game
Boot Method 2 - Insert freeloader disc, eject, reinsert freeloader, eject & then insert import game
Red screen - Only happens if using a RGB Cable, revert to NON-RGB slot in tv or you use either component or composite cable
Black screen - Revert to alternate boot method
Black & White screen - TV doesnt support NTSC signals
Manhunt 2 (USA)
Boot method 1 - Red screen if using RGB Cable, perfect using Component or Standard Composite / Scart.
Boot method 2 - Works perfectly with all cables
Smash Bros Brawl (USA)
Boot method 1 - Red screen if using RGB Cable, perfect using Component or Standard Composite / Scart
Boot method 2 - Black Screen, though audio can be heard
All in all a great product that plays pretty much every NTSC Wii game there is & a few NTSC gamecube games too. Highly recommended for the impatient like me.
