Reading the rules of the forum should have been the first thing you did.
The second thing you should have done after reading the rules would have been posting an inrtroductory post. As indicated hereMoving on.1. New members are expected to create a new post in the Introductions Forum. A brief post will suffice to both introduce you to our community and to learn to create a post.
Well we need to find out is what region are the games in question? And what region is your Wii?
If the games are out of region then there could be compatibility issues with the video output. That is my gut feeling by the way.
Another thing I want to know is you specifically mentioned WODEflow, does that mean the games in question work fine when launched via the WODE joystick and LCD? If yes then please post your issue at the offical WODEflow report pages. The guys have asked that all WODEflow type issues be directed to them.
Will check back later.
