sierra/objs_lsl/mnln.asm: Use division quotient, not remainder It calls a routine twice to make a division (L125C) but doesn't check the right register for the result. The result is returned in reg U and the remainder in reg D but the procedure expect the result to be returned in reg D. The divison routine seems to be correct because it is properly used elsewhere in the code. Patch by Guillaume Major and Robert Gault.
