Atari 7800 joystick pad hacking

Which is the easiest way of getting my multi-iconsole fight stick working with the 7800.

 

A) disassembling a 7800 for the PCB if it's the mechanics failing and not the electronics and soldering discrete wires to the contact points?  If so may I have a diagram of where to solder for my friend to follow?

 

B) building a 7800 logic board.  If I read the logic right. The four joystick directions and the ground and, if necessary, voltage,  are 6 straight pins.  The buttons are the most complicated thing the 2600 fire is the 2600 fire in 7800.  And the separate left and right fires have a separate pin.  But the left or right pin and the common 2600 pin must actuate together.  I don't know if my Hired hand can do that.

 

C) just buy an already built PCB from Edladdin.

 

D) buy a genesis to 7800 adapter.  The main problem I heard with that is ping.  

 

By the way my joystick starts out at all discreet inputs and gets encoded four systems from NES and beyond.

If it has a Genesis setting, an Edladdin Seagull or other Genesis to 7800 adapter is probably your easiest choice. If you don‘t care for either button to register as the single button on the VCS you can probably hack something together as well consulting the schematics. Don‘t know whether the resistor for the second button is a must or just required to differentiate between 1 and 2.

Just wondering about controller ping.  Should I assume the joystick ping is quicker by doing surgery on a 7800 stick.

 

If so. Are there any "surgical diagrams" of where to solder a working 7800 Pro Line?

 

Yep, they are on another forum and when you find it, stay there.
