Unable to launch MKW from home menu

[unknown394]

I have my MKW ISO set as the default ISO so it shows up on the disc channel

Every time I try to launch MKW through the disk channel Dolphin gets stuck in infinite black screen

The title on Dolphin's window never switches to MKW and stays at Wii Menu; framerate stays at 60

I'm using the newest development build and a copy of MKW with the newest Wiimmfi patch
