Some Games Not Working On My Wii. Why??? And Help!!!

I Recently bought some games like:

Iron Man

The Incredible Hulk

Super Smash Brawl.

But they are all not working some other games are working thought. if you now how can make them work plz reply

If they are new games then more than likley the lens is dirty in the Wii. Games like Super Smash where it is duel layerd disk are harder to read with a dirty lens. On my Wii I cant get Super Smash Bros to load up. If you smoke while you play the Wii it will dirty the lens quicker.

Search for some lens cleaners or some do it yourself solutions.

yeah, you might be useing other region games
