I've recently bought a Gremlins 2 cartridge and was planning to make a Dark Gimmick of it.
So I burned and soldered the EPROMs as described and the game works, but no expansion sound.
Now my question, I've used the schematic in the attachments and I don't get any expansion sound either. Do I have to wire something to the 5A chip or is this not compatible with the AY-3-8912 chip?
Also, do I need to connect clock anywhere else or just to the 74LS74?
Any help about Sunsoft 5A + AY-3-8912 appreciated.
