    Came across this thread showing a simple mod to restore SMS compatibility with the Genesis 3 (VA1).

    EDIT: just did the the mod (along with a region change to Japan), and it doesn't appear to enable the FM synth with the Powerbase FM. Looks like there are 2 wires that need to be connected from B1 and B3 on the cart port to "Audio Circuit" as mentioned here:

    Any idea what lines on the motherboard to connect to for the pass-through audio?
