Is an INTV2 -> INTVFB cable considered "bidirectional"?

[tripletopper]

I heard an INTV2 to INTVFB cable from 8bitwidgets.com is bidirectional.

 

I heard the Flashback makers (At Games) confused the male and female numbering which are horizontal mirror images of each other.

 

If that's true then a retrogameboyz.com joystick or adapter should work with a flashback modded INTV1.

 

Just checking my facts.

The flashback controller pinout is all over the place, not a mirror of the sears/intellivision2 pinout. So I don't think those adapter cables can be used in the reverse application unless you change the gender at each end.  8bitwidgets should be able to make an adapter cable for your application.

That's actually a good idea.  Buy a double male DB9 and buy a double female DB9.

 

I'm surprised they don't advertise it like that where it could be a "reverse adapter" if you buy one double male and one double female.

 

So it's just the pin remap adapter.

 

That's why all those joysticks sites say wire color to color, not pin to pin,  in case you got an Ethernet crossover cable by accident which happened to me when I originally got my Toodles Cthulhu installed by my joystick maker.

 

Funny thing is my guy who wired it refused to follow the directions on the internet and insist on pin to pin wiring, and one of my cables happened to be a crossover ethernet cable and only the Dreamcast worked on the Cthulhu.  

 

We all live and learn.

You cannot rely on color to color because different cables during different parts of manufacture could very well have different colored wiring inside the harness. It is always advised to verify Pin to pin connections to be sure you have everything wired properly. I actually made a color code chart when I was doing more FB intv controller to INTV2 wiring and have since come across a few FB controllers where the colors were a little different and I had to go back to verifying pin to pin what was connected to where.

I was talking about an experience  with a fight stick which was mapped with an Ethernet adapter.

 

You have to make your own Ethernet adapters.

 

The fight stick makers recommend wiring destroyed Ethernet heads either pin to pin or color to color.  (I forget which) My stick maker insisted to wire it the other way, and would only guarantee it that way.  So the Dreamcast coincidentally worked but none of the other systems did.   As it turned out, that's when we looked up notes about  A-wiring, B-wiring, and A-B crossovers.   I happened to bring an AB crossover, and it caused that effect.

 

I just bought random Ethernet cables and they turned out to be AB crossovers.

 

That's the reason why you don't blindly wire by either color OR pin but analyze whether you have AA, BB or AB, and deal with it appropriately.
