SCC (U) does, but it's seemingly at random. I'm not sure what makes it stop working and I'm not sure exactly what needs to be done to get it working again. However, before I deleted it because I'm obsessive compulsive that wants things to work properly even though I don't want to play them or even collect them, it had gone from working, to error code -5, and back to working again. I will say that it's definitely not a problem with the extinfo though.
Sorry I can't really be more helpful. You could try formatting I guess. It's one of the things I had done for unrelated reasons mucking around with my card between it not working and it working again.
