Just got a CycloDS today, and installed 1.53 firmware on it. When I boot it up, I get the loading screen for the Cyclo, then immediately as soon as it loads, my rumble pack goes constantly (and loudly!). I've went into settings and changed Rumble from Disabled to Low, etc, they all give the same result. Rebooting, etc, or removing the rumble pack and re-inserting makes no difference. The rumble pack/DS has worked fine for months using an M3 Real. Any ideas?
