I run my back-up games from an HDD using wiiflow. So far I haven't had any real problems, but recently I tried to play Resident Evil - Darkside Chronicles, but all I got was a black screen. For some reason, though, I was able to run the game perfectly through USB Loader GX.

What could have caused that? Are there some games that simply won't run on some USB loaders or could that be a problem specifically related to my installed Wiiflow?
