Title: Help ID my famiclone!
Post by: ericj on March 15, 2008, 07:16:14 pm
I've been trying to figure out who manufactured the famiclone I have. I've looked on various sites but haven't been able to find one just like the one I have.  Besides the controllers and the component outputs on it, it looks like a cast of the real Famicom. Internally, the board is much simpler, though. Can anyone help me figure out who the manufacturer of this is? I only paid $2.99 for it at a Goodwill thrift shop, but it needed a little soldering before it worked 100%. This is the famiclone I can thank for getting me interested in the Famicom.  ;D

Whoa never seen anything like that before :o
I assume the green board is a glop top NOAC... but then why does it have external RAM chips? ???
Could you do some tests (colors, sound, etc) to see if it is a standard NOAC?

Very strange animal you have in there ;).

I'd be happy to but would need some direction from you. Thanks for your help :)

I made this little flash video so you can spot the difference (670 KB):

Interesting  ;D.  Never realised Famiclones sound different.  I thought the sound chip was standard on all machines.  Good video!

Yeah they do. What happened was that the pirates *cough* reverse engineering team screwed up while replicating the NES sound generator. The square wave channels have several duty cycle values selectable by software, they swapped 25% and 75%, so a NOAC interprets music wrongly. Maybe they didn't catch the difference by ear, or by the time when they realized the screwup it was too late (and expensive) to correct, or they simply didn't care. Sadly there's no way to correct this externally, you'd have to build a complete new NOAC from scratch. Also NOACs have a slightly different color palette, but since every TV is calibrated differently, that's hard to spot by eye.

Just listened to my clone and NES with SMB at the same time since I have multiple copies of the game and the clone sounds exactly the same as the NES. To make sure I would be able to perceive the difference, I tried my Power-Joy clone it and it definitely sounded different; the Power-Joy sounds more like NOAC.

Hmm, guess that would my famiclone has a nes chip?   ???

I'm starting to think that your Famiclone has an early, rare or alternate version of the NOAC, since it has no embedded RAM (it's on external chips, the two big ones near the cart slot) and it has no characteristic NOAC sound. As I said before, Very interesting animal you have there ;).

Interesting! You're awesome, dude!   ;)

Guess it was a good buy at $3. Besides, it got me started with this whole famicom collecting thing  ;D

If it were a different version of the NOAC, are there any nes or famicom games that may not play correctly on it?
