Exactly what does "nothing happens" mean? The same, identical behavior? A return to the Wii menu? What? Via disc? Did you burn with Imgburn @ 4x or less on Verbatim or Taiyo Yuden DVD-R media? Does this image behave on others' Wii (in case you'd know) to rule out suspect disc image? Did you check to see if Parental Controls have been set to preclude you from running this game? What System Menu/region? What softmod guide? The questions are endless; this means if you're seriously wanting help, a more-complete picture needs to be given.
