Hi, I have just come in posession of a famicom clone, I opened it up expecting a NOAC but there's a proper NES setup, a PPC, a CPU, wram, vram(?) and the other logic chips. The PPC and CPU are removable so I might try to plug a official one in there later.
But for the time being, it's got a 60pin connector. I want to wire up a 72 pin connector, however, i'm unsure where the extra connections would go. would they go directly to the cpu/ppu or isn't it possible to make that conversion?
(I'll post pictures later!)
The extra connections in a 72 pin connector go to the expansion port and (in frontloaders) the CIC.
hm, since this has neither, does it matter?
I'm thinking that the lockout won't unlock therefore the CHR/PRG can't be read? (I don't know too much about how it all works yet).
How old is the clone? I knew that non-NOAC clones were made during the 8-bit generation, but I thought that once the NOAC hit the scene, non-NOAC clones were a thing of the past. It would definitely be an interesting development, if non-NOAC clones were still being made today.

I'm pretty sure that the trouble maker is the CIC that's in the console. Since your console does not have one, it doesn't matter whether the cart has one or not.
I don't know if it's pins should just be left unconnected though, but that would be my guess.

No NES mappers implement this, and only a few Super NES mappers (e.g. SA-1) implement this.
Those particular SNES games seems to have a surface-mount revision of the CIC. The CIC in regular SNES games is the exact same as in regular NES games, with the exeption that japannese SFC games have a CIC too, unlike FC games that doesn't. I think an additionnal variant of the CIC was made for Japan.

NOAC debuted with Super 8, anything after 1994 or so is game. Micro Genius I believe still makes discrete clones, they likely don't manufacture the parts however, just use the NOS.
joe78, just leave the nonexistant pins disconnected, CIC is irrelevant to Famicom. Better yet, buy a 72->60 adapter from Liksang or somebody, it will be easier than soldering 60 wires and infinitely more sturdy.
I have one also with discrete chips, amusingly though it's a PAL version. The box has a Chinese pricetag (I think? 99.00 somethings) and another sticker on the box gives an address to a company in Malaysia.
It's one of these:

mine is one of these:

If discrete clones are still made today, then why doesn't a clone maker step up and create a quality clone, which is compatible with all Famicom, NES, and clone games and peripherials, out of the box, without need for adapters?
Nobody is going to produce new CPU and PPU, that became uneconomical 15 years ago.
