FAMI-NES     (Adding 60 pin famicom catrige slot to NES and adding (DB-9) famiclone joysticks

Hello, and I would like to present my Nintendo Mod, using which your Nintendo will be able to work with famicome cartridges

and famiclone controllers.

I decided to make this mod, when I accidentally came across an original Nintendo.
Because in my country of Bulgaria, we primarily have Chinese clones of the original Nintendo console, therefore the

controllers and tapes are also such.
Actually they are on the Japanese standard - famicome.


WE WILL NEED:  

- A NES console with a disabled lock-out chip
(disabling the chip is easy, I will explain how its done further down)

- One 60 pin-slot from a Nintendo clone (famiclone) or an 8-bit ISA slot
(the ISA slot has two more pins, which is not problem. The problem will later when you won't be able to attach the slot to

the console.)

- Two male serial ports (DB9) or (DB25) depending on the controllers you'd like to make your NES work with.

- 60 wires for the slot and 12 for the controller ports
(I'd recommend that you use single-fibred cables)

- 4 resistors with a resistence of about 3660 ohms (only if your NES is eurupean version)

And last but not least - a lot of patience with the soldering



LET'S BEGIN:



The Lock-out Chip  

We open the console and the first thing we will do is disactivate the lock-out chip, which is responsible for authenticating

original games.
If the chip for whatever reason cannot achieve contact with the chip contained in the cartridge - it sends periodic signals

towards the processor - which then forces the console to reboot every second.
This constant rebooting could be either due to a non-original cartridge or dirty contacts.
So what we will do is disable the chip so that we can play famicom games which don't have the original chip.
Simply break the 4th pin left to right on the botton set of wires.

THE SLOT  

After breaking the 4th pin of the chip we can begin soldering the 60-pin slot of famicome directly on the main-board of the

nintendo.
The 1st to the 30th pin on the 60-pin slot will be soldered on the back-side of the 72-pin slot of the Nintendo itself.
And from the 31st to the 60th should be soldered directly on the main board of the NES

NES 72- to Famicom 60-pin adapter  
---------------------------------

Outside the box are the 72 pins of NES cartridge connector and inside
are the corresponding Famicom pins.

https://drive.google.com/open?id=1S2TwZNPz0L2UZoQM3HfhxVEVJFlnUOvy

* Pins 45 and 46 on the Famicom connector are connected together.



Notes
-----

1) NC means "No Connection" as you probably guessed.

2) For some reason NES has pin 62 as CHR A11 and 63 as CHR A10 and not
  vice versa as would seem more rational. In Famicom this situation
  does not exist. Keep this in mind when building the adapter.



Unconnected NES pins (and why they are unconnected)
---------------------------------------------------

Pins 16-20 and 52-55:

  These are the pins that go to the expansion connector in the bottom of
  the NES. As Famicom doesn't have (this type of) expansion connector,
  these pins are left unconnected. Only the NES pin 51 is connected to
  the two (one) expansion pin of the Famicom.

Pins 34, 35 and 70, 71:

  Famicom does not have the security chip so these are unnecessary.

Pin 37:

   I don't know the reason why the equivalent of this pin is not
   found in Famicom.

CONTROLLERS  

Here we will use the resistors with the 3600 ohms resistance
(if you don't have just those then you could use ones with greater resistance -
for example I ran out and used 2 resistors rated at 4500 ohms and I still got it to work)
They are used as follors:
The first resistor goes towards the pin that emits 5 votls and the "Latch" signal.
The other one goes towards the 5 volts and the "Clock" signal.

That's on the side of the serial ports - as for the other side - you'd have to solder the corresponding wires on the original

port of the NES as you will see the wires are soldered after the dioded and not directly on the wires going towards the main

board

There is another option, to make those diodes to short circuit:

This picture shows how famicom pins corresponde with NES ones,the colors on the famiclone side are not important, important

think is the positions of the pin outs.

COMPATIBILITY  

Unfortunately some of the pirated famicome games are not completely compatible with the Nintendo, due to some missing

elements (condensors, resistors, etc.)
With their proper implementation, however, problems such as a bouncing screen and certain bugs are almost eliminated.
Unfortunately again, some of the empty spots where components are missing it doesn't say what their specifications ought to

be.
Some boards, sadly, don't even have empty spaces for component attachment.
Modding tapes and adding components doesn't affect gameplay in any way when playing on the clone consoles (famiclone)


Good luck with the modding

Nice mod 

Since it's a pal Nes, famicom games will be slowered ?

Yes   And thanks for the opinion

HELL!!! Where is the hot glue? It will fall apart! LOL Just kidding. Actually very good example "how to".

Hint #1. You can use round IDE cables or multicore wires from old LPT cable. first one thin(read compact) and flexible, but might be not very hot resistant. Second one you can find  105C rated, so they are quite heat resistant.
Hint #2. Keep all wiring as short as possible, otherwise you might get random weird glitches.

Q. Multicart on the last photo. Could you please make macro photo of PCB from chip side?

there is no hot glue, but there is a universal glue I know about glitches  but the cables can not be match short . What is 105C? capacitor?
and the multicart with normal chips you mean? this think is a one LED that I just put for fun , but later removed it  thanks for opinion and hints 

[80sFREAK]

105C degrees rated cable. Some LPT cables have quite hard melting insulation, so that's it..

Yes, multicart with chips. I'm curious about master mapper. Also what's the name of multicart?

priceless!    

and the console hack is nice too 

[sconley666]

Here is an interesting version of the same idea.  Nice job by the way.  In this version the guy put the fami connector on the top and did a nice job making a dust door for it as well.

nice job  

60pin slot is underNES, thumbs up

[Pit]

Mine just need the dust cover 

I found a junk snes shell, I'm gonna take the dust cover to put on the Fami slot.
