I have a Wii USA that had 4.1u with dvdx,HBC,Cios and wiikey 2 modchip, some games would not load. I decided to use this tutorial to see if I could make games work, but after updating to 4.2 and installing all IOS, Cios. When I put the dvd backup it appears the title and when I press A to play screen stays black. Why? Some games would not even load, it says error.. reset wii etc. Thanks
Use ModMii; the link is in my sig.
Why don't you give him a little more help than simply use modmii? That advice won't fix his problem since it sounds like he is attempting to launch games from the disc channel... I am all for people using what is best and all, but simply replying to every question someone has with "use modmii" is ignorant and not helping anyone other than you and your post count.
To accurately answer his question, try loading the game with neogamma, then if it works and you want to use the disc channel you could look into
PoC. I would recommend ditching the wiikey, not sure if you can do it without taking it out on the new ones. On the first gen ones, you could initiate an firmware update and unplug it at 70%.
