Hacking WiiFlow FAT32 Issues

[Wellington2k]

I just decided to format my WBFS drive to FAT32. I've created two partitions, both FAT32, one for the data (to replace the SD Card) and the other for the games. WiiFlow (version 4.2.1) boots up fine and shows all my games, but when I try to boot one up, the Wii's disc drive spins and I'm presented with a black screen.

Any help?
I have cIOSx v19 installed, in case you need to know.

I got it to work! For those who need help, I just figured out I had to force cIOS 222.
