I've got the same error, still can't solve it =\
I worked my way through the guides here, and most of my games work, except for this one. Little King's Story (NTSC, not PAL).
When I start the game, It shows the Wiimote Strap warning, then goes to a black screen. The controller seems to disconnect on most ISO's, but seems to be OK on 222.
First i think you both should Introduce Yourself Then you will be given valuable information by the modders.
Secondly have you tried using the video patch for the game region in your usb loader options.
