Has anyone had trouble with using a code breaker and w/ MGS2?
 

I can't figure out what is wrong with my game. I am using a code breaker w/ my game and at the part where you talk to Ames it doesn't work. I aim the mic at his chest and there is no pacemaker sound. If you call to him he just acts like all the other hoastages. I tried doing it without the codes on but that didn't work either. has anyone else had this happen to them?
