ext controller port on famicom only for player 2?

[133MHz]

BTW could anyone please give me the pinout from one of these 2-player DB15 controllers? I can't seem to find it anywhere and I need it to build an adapter to test my TwinHead PC100.

Was anyone able to provide the pinout for the 2 player DB15 controller? I'd like to know this to build my Famicom to NES controller port via a Four Score. I couldn't find it online anywhere.

Yes, I've managed to figure it out, even D2 and D3 which are necessary for the light gun .

Here you go:

Perfect! Even better than expected. Somehow I knew you'd have that figured out.

133MHz, was the schematic you posted for the DB15 to NES controller ports for only the Twinhead PC, or should it work on a Famicom, too? I finally got the parts to make mine and soldered it all together to test, but it doesn't work. Thought I'd ask before looking up the Famicom's DB15 pinout and comparing it to the one in your schematic.

The Twinhead PC is 100% Famicom compatible. I've tested my adapter on a real Famicom and it works perfectly.
Are you using a multicart to test the controller?
