FC Twin. Snes/Nes with pics.

Well it arrived today.

It seems to play Nes games like a Yobo.

And it does really well on all the Snes games I've tried.

The controllers feel just slightly lighter than the Original Snes controller.

And the FamiTwin controllers work on an original Snes and the original Snes controllers work on the FamiTwin.

The Snes part of the Fami Twin does pretty good but it does have some problems.

The biggest is that he output is slightly blurry with slightly muted colors.

Here is a pic to demonstrate. The original Snes is fist and the FamiTwin second. Notice the muted colors and slight blurring.

Now this is on a 60" Sony Hdtv. I don't think this would be that noticeable on a 5" screen.

Overall Ithink this would be a Great system to make into a portable. In fact that's what I plan on doing

yea wow the snes part is about 25% smaller than the mini by the looks of it! exelent, i hope these get cheaper soon lol

Hellrazer, can you take some pics of that PCB in the back w/ the caps & RCA jacks & whatnot?

hailrazer · Post by **hailrazer** » Fri Nov 24, 2006 7:20 pm

Measurements :

Snes board -- 3 5/8" x 4 1/2"
Cart slot extends 7/8" on each side.
Controller ports extend 1/2"

Nes board -- 1 1/4" x 4 1/2"
Cart slot extends 1/2" on right side only.

Power/AV board -- 1 3/4" x 4 5/8"

Looks pretty nice, and the video might be an issue with the rgb -> composite conversion circuitry.

Here you go. I removed the pesky heatsink for the 7805's

I can think of two reasons the video is blurry:

a. They tried (and failed) to smooth the video, as some emulators do. (They obviously never heard of Scale2x...)

Or, more likely:

b. It's just really cheap hardware.

Have you tried any NES carts yet?

I've tried 20 or so Nes carts and they all work fine and look good. The colors are fine and theres no blurrng. It does have that slightly "tinny" sound quality but all NOAC's do.

So for some reason the video quality is only blurry/muted on the Snes portion of the FamiTwin.

hailrazer, first of all thanks for the pics.
Second, can you give me the number of the chip directly behind the power plug? Looks like that may be the video encoder.

Here you go:
SONY
CXA1145M
433C37K

And here's the datasheet:

Awesome. The cxa1145 isnt the greatest encoder, which explains the crap composite picture. The good news, is you can easily tap into the RGB lines since they are right there. But you are right, for a portable it probably wont matter. Unless of course you want to use something like a PSone screen, in which case using the RGB would be awesome.

So right now you own the best candidate for a SNES/NES portable known to man

You better not disappoint us

I'd guess the reason the NES section looks fine is because the video encoder is built into the NOAC glop top. The CXA1145 rgb>composite chip is (i'm pretty sure) only for the SNES part.

No doubt, this is a great find. And I'd agree that the video encoder is probably built into the glop-top for the NES part, as it is on almost every other NOAC.

My REAL question, though, is this: Are the patents on SNES even out of date yet? I mean, NES patents just recently ran out as far as hardware goes, so how can SNES be upon us already?
