Hello, I`m having some problems. I made the whole thing with super mario cart and cartridge slot from old broken famicom.
Well, the problem is that mario cart doesn`t have some pins on the board. Pins 37 and 38, 14, 15. So I don`t have M2,Prg r/w and IRQ connected. Also pins 57 and 58 are short on mario cart but not short for 60pin cart....
I'm not certain of any good solutions, but for mediocre ones- you could probably try either adhesive copper tape (sold for stained glass making) or a car defroster repair pen to make a few fake pins.
Well, I do have some pirate cart that have all pins on the board, I just wanted to try to fix this one since it takes a lot of time to solder all wires, but if this can`t work without these pins I`ll make a new one.... here`s the cart....
And one more, what do I do with pin 37 (CLK) on the left pic, do I connect it to VCC or just leave it? All other pins are matching....
Same problem than for FF3...
And you should probably remove the CHRROM to make a decent adapter.
You're quite brave to solder 60 wires.
I made it with the second cart, I did remove roms (cut off) and connected all pins in order, but still nothing... can`t find the problem....
Leave the CLK line disconnected, it's an output, not an input.
Note on the Famicom connector that pin 18 is "CIRAM" A10, not another normal CHR A10.
According to this:
http://nesdev.com/NES_ADAPTER.txt
everything is in order, I even aded 45-46 to 51 exp pin.... don`t have an idea....
what kind of problem are you having? does the game boot at all? or does it just display greyscreen?
No boot, like there`s no cartridge inserted, I even soldered famicom cart directly to NES board (because I got really pissed off) and it didn`t work, so I gave up. The given pinouts are probably incorrect....
I have a cheap 72 to 60 pin adapter that works (I used it to play stuff on my famiclones before I had a NES), if you want I can take some pictures of it. Since it doesn't have a case, you should be able to see all the connections.
EDIT: Wait, I got it wrong... You want to play Famicom games on your NES? I usually use the "72 to 60" or "60 to 72" expressions considering the first number as the cart and the second as the console, because you insert the cart into the console, in that order.
So, don't the
pictures of the Gyromite adapter help? I also have an adapter for this, But for some reason it never worked. It's pretty worn out though, so I'm sure it used to work. I might take pictures of it too if you want.
when i builded my famicom adapter, (i used same pinout as you) first i couldn't get games work at all. After i added 470ohm resistors to datalines (D0-D7) it worked!
Thanx for helping out guys, I did compare my adapter to pics (found on net large pics with both sides), I know there are cheap adapters to buy but I just like making my own stuff....
@sepi:
can you tell me what pins exactly (there`s chr Dxx and PRG Dxx) and is it only two pins you mentioned or is it from D0 to D7....
And one more thing, this PRG /CE pin is confusing me because I don`t know what ``( /15 & /M2 )`` means....

Hey, that's the exact same adapter I have. A real piece of work...looks like someone just took a cheap NES clone connector (screw holes and all) and hand-soldered it to an equally cheap PCB. I had to bend out all the pins in mine with an X-acto knife because they wouldn't grip carts properly. Best $20 I ever spent! -_-
Mine had a pin that wasn't soldered, so I had to do it myself. I believe I paid $10 for it. From LikSang I believe, when they were still around.

I don't see any lockout-related circuitry. How does this board defeat the front-loading NES's CIC? Or is it only for toploaders and famiclones?
That is a pretty good question. Unfortunately, I couldn't get this thing to work yet, so I can't answer you. I was even thinking about adding a CIC to it, but haven't actually thought it through.
On the other hand, it had a plastic case with a long stripe of fabric attached to it (used to pull the cart out), indicating it was also meant for use with front-loading consoles. Maybe it assumed modded consoles?

I still have one that had the long stripe like you mentioned. But this one was not bought at liksang: it's fron the nes era when bootlegs were common.
I could always open it someday and check if there is any special chip in it.
Still nothing!!! It`s not working with resistors too.... It`s definitely this CIC circuit. I isolated it with tape on original cart and and Mario is not working now.... So I will add this IC to adapter to see what happens....
Finally!!! It was damn ic (and probably resistors). Working good now!!! Thanx drk421 and all other members for helping out, I lost hours trying to figure it out....
Hey, pretty cool! Congratulations, your converter looks pretty damn useful now!
I'm thinking about adding a CIC to my converter. Although that can't be the reason it's not working, because I tried it in a top-loading NES. Anyway, once I figure out what's wrong, I'll add the CIC.
Well, the first one I made was exactly like the one you have, so it`s problem with this IC, maybe that top-loading NES didn`t have security pins....

I'm not digging the way that right hole almost cuts completely through a trace. Really sloppy work.
Something interesting: I have a Honey Bee Fami-to-NES adapter that has space for a CIC, traces and all, but came with the usual "zapper" components carelessly glopped on instead. I just pulled the scary crap off and dropped in a CIC from a Tag Team Wrestling cart, and now I have a nice-looking adapter functionally identical to an NES-JOINT-01 (the red wire is for exp. audio):
I wonder if they expected people to do that, or if they had a CIC clone in the works at one point?
when i made my adaptor, i didn't have a 60pin connector so i made one by sawing off an old ISA connector.
