Thanks. Mine, doesn't works but if I send some FM sound test, the unit works. What could be the issue? |

I'm also having the same issue, both the cart and expansion port are clean so not sure what's going on. | |

Have you changed the bios capacitor to let the everdrive works? |

I did. I can try swapping it back with the original value and see what happens. BTW it's actually for the reset circuit since the Mark III doesn't have a BIOS. EDIT: Just swapped out the reset capacitor for a 1 uF cap, not only is FM working on After Burner but the Master Everdrive still works. Problem solved! |

Nice! I tried but with no success. Changed C18 with 0.22uF, 0.47uF and 1uF. With 1uF, FM is initialized correctly but the everdrive nope. Have you the cinise version of everdrive or the original one? |
