When it works normal it is not suppose to do that it is suppose to load the game. I had my working for a while and it just started doing that. A couple people recommend to re install Cios 38 rev 13 on the 4.0 but somebody says even under rev 13 on the wii 3.2u is not working.
my thread i started
This is simialer problem but goes to black screen
from some reading on other boards it sound like the dual partison support is lost after rev 640. I would try dl a rev prior to 640 and see if it fixes your problem.
SOme people have had luck by deleting the fat32 partision or by unplugging the usb and loading gx. THen when menu ask to select 249 or 222. Select 249 and the games work. I did not try either just relaying the information.
