I recently got my M3i in the mail today, and I am impressed with it so far. I have a couple of problems with it, however. The main problem is that I cannot pass the Castlevania test. The Castlevania test for Dawn of Sorrow doesn't even start. It gets to the beginning of the video and then crashes. I'm using 4.3f as my loader, under Sakura. I have an 8gb Kingston Micro SDHC (Class 4), and it's made in Japan. The Portrait of Ruin video plays flawlessly. Should I just not bother with the video, since my card should run games near perfect?
