Well I just bought a DS Lite Rumble Pack, and it arrived today, and it seems to be glitchy with my EDGE firmware v1.5. I put it in my DS Lite, I boot up the EDGE, I select Dirt 2 since it has rumble capability, and right when it loads, the rumble starts up and won't stop at all. I let it run for 3 minutes. Is anyone else having issues with their rumble pack on EDGE firmware v1.5? I tried another game, Metroid Prime Hunters, and it seems the rumble starts up and won't stop either. I tried it with my R4, and it doesn't have any problem whatsoever. It's just the EDGE.
