Post subject:  Mod Retron 1 with 7404 to play Castlevania 3 -Diagram Help..

Can someone help me find a diagram for modding the Retron 1 (nes/clone), so I can play Castlevania 3 on it? I bought the "Hex Inverter IC 7404", the picture below is an FC Twin diagram and not the Retron 1 board. I am including my guesses where the points would go but my confidence isn't their and would ask for confirmation and help.

The wires go from 1, 2, 7, 14 on the Hex as shown here:

So I gather from images I found online for the disassembling of the Retron 1 the solder points should be like this:

Is this right??? :?: Also do the wires on the HEX #1, 2, go to the same solder point on the Retron 1 board #65? Thanks. :?

Edit: Nvm the last question, I got it. 1Y (left) & 1A (right). :mrgreen:
