I've tried re-downloading and still the same problem. The SGB mode won't turn off permanently for some reason. I change it to "Off" then I save the settings and try. It plays in B&W as I wanted. Then I turn off then back on the DS and check. SGB still says "Off", but if I load a game it uses SGB anyway. I have to go back turn it on then off again. Lameboy.cfg only show scrambled digits of some sort. What does yours say?
