Do you have pre/priiloader installed with the correct region hacks? Also, if you are trying to play a NTSC game on a PAL wii, make sure your system menu language is set to English. You may also need video mode patches if you are launching an out of region game.

You may want to install the latest WiiKey beta update (v1.99).

You certainly seem to have all the ios installed if you can start it in NeoGamma.
