Famicom AV Mod Help, 3.5mm to AV

Hey everyone,

I recently got a Famicom, and it only works on one TV, has the worst reception imagineable, and has FM radio interference somehow. But I have played through a game on it on a lucky day, so it does function.

I saw this mod, which seems to be popular:
http://assemblergames.com/l/threads/guide-av-mod-your-famicom.49263/
But I don't want to drill holes in the case. So I also found this service this guy provides:
http://www.retrofixes.com/2015/02/famicom-nintendo-av-led-upgrade.html?m=1
But I'd rather do the work myself.

I have much experience soldering, but next to no knowledge of this kind of stuff otherwise.

So basically, I was wondering what changes would need to be made to the link 1 tutorial, to accommodate a 3.5mm jack like in link 2.

Could someone give me beginner directions on how to accomplish this? I would really love to be able to actually play my Famicom.

Thank you for reading!

 

Well you could do what I did and run thin RCA cables out the controller holes. I also used this circuit as it's the one in the AV Famicom and it's easier to do/install.

It won't provide the best video quality but it's much better than RF. If you wanna go better, install Tim Wirthington's NESRGB board and replacement power/AV board (included in Famicom version of the kit) or Kevtris's upcoming Hi Def NES (NESHD) HDMI mod. The NESRGB board will provide a better composite video signal, s-video, and true RGB using the original NES PPU. The HDMI mod taps into the digital A/V signals on the CPU and PPU and converts them into usable HDMI signals using an FPGA. This will provide the best audio and video quality possible out of your Famicom.

 

Honestly if you want the parts I will sell them at cost.

AMP,Port & Cable.
I do not have a tutorial written for the Famicom but I have some pictures that will guide you.
I also have parts and tips for Jailbar elimination that I can include.

 

That would be fantastic! And as long as the pictures are instructional enough for a total beginner, that should work great!

If you PM me, I'd be happy to arrange ordering them from you, assuming they're not listed on your site.

Thank you both so much for replying!

 

You should consider a 4 point 3.5mm stereo jack, like the ones they use in camcorders and RetroBits GBA/NES/Genesis adapters if you only want one hole. But they are a bit more complicated to solder in compared to two RCA jacks. The mod does get easier each time you do it, and obviously wire positioning is the biggest time sucker. Nintendo made the Famicom quite compact.
