There is another thread on here regarding the shaker motor and some issues. On some MMs the shaker does not shake on catapult launches, only when the castle destructs. This is the problem with mine. I have the latest shaker motor driver board and latest chip installed from Pinbits, but still no shake on Catapult launch. I have game Rom 1.09 installed and tried 1.09 c, but it did not make any difference as the shaker only shakes when the castle is destroyed. At one point pinbits said they were working on a revised code to address the problem but that was nearly two years ago. Your game may work fine, but some original games don't seem to work.
