I got Drill Dozer from the Circuit City sale a few days ago thanks to a friend, who sent it to me all the way from the east coast. Well, it arrived today, and I tested it... and it doesn't rumble.

I'm not sure if there's something wrong with the game. I set the rumble feature to on, and I have a GBASP (first version). The connectors aren't dirty and the battery on the system is fine. But I played through the entire first level and nothing happened.

Is the rumble feature supposed to work right from the start, or did I get a bad cart? I don't want to have to ship the thing back to my friend so he can send it off for repairs... :\
