I have found something new today. With DC>off, I rad Fire EmblemoR[gc]. I had black screen, but from memory I navigated menus until I got from management screen to in-game. Upon this screen change, graphics finally showed. So there seems to be only initial problem with displaying graphics until certain screen change occur, at least in this game. However, there are still too many other games with this problem anyway.
