I am using a Japanese model 1 mega drive. I can hear sound effects when playing games like Sonic CD and Spider-Man v. King Pin but I have no background music at all. I have sound from FMV games.
This same thing is happening on my Nomad. Before the mod i had very few sound effects from said games and no sound from FMV games. After the mod I have the previous described sound effects with no background music. And full sound from fmv games. I figured it was just the nomad but now that is suspect.
Is it my cart or did I miss something?
