Hey guys I just bought a Secret Service and I'm in the middle of shopping it out and fixing things. A couple of issues I'm trying to figure out. One there is a pretty loud hum all the time. Not sure if this is infamous "Data East" hum or not. If it is, how do I fix it? Second issue is during the "Secret Agent Man" theme during game play the song seems to change tempo and pitch mid song. Is this normal or something malfunctioning? Seems weird to program it that way. Thanks!
