Sorry I have no idea as I've rarely used MorphOS and rarely used SDL on an Amiga[-like] OS. Why these things go wrong is anybody's guess, but the logical course of action is to investigate the common features of the two bits of software. Since graphics are the problem, and the graphics for the OS itself are ok, I think the logical starting point is to investigate anything which is specific to graphics and is shared by both games. I'm assuming that this is going to be SDL
