My av famicom (rgb, s-video, stereo sound bass boost, etc)

Post by Drakon »

Here's my latest av famicom.

There's many advantages to the AV famicom. The AV famicom is the only known model of the nes that doesn't have video interference when you modify it to use a rgb ppu chip. Also the av famicom is a top loader meaning that games will always work on it. The av famicom has controller ports for standard nes controllers and it's small and looks nice. Here's what I did to my av famicom:

Here's how the system looks when everything's been put back together:

As you can see, this av famicom has been modified almost as much as humanly possible. Here's the features of it:

This av famicom outputs true rgb, s-video, and composite video from the multi av port at the back. This multi av port is the same video port as you find on a snes, my system is wired the same way as the snes so all you need to do is buy snes rgb/s-video/composite video cables to get the video signals out to your tv. Here's some comparison screenshots between the s-video on my av famicom vs the composite video from a standard non-modified nes:

That takes care of the eye candy. My av famicom also features a very nice custom audio circuit. This audio circuit increases the bass, and it also does a better job mixing in all the audio than the default circuit on the famicom/nes. This audio circuit also does psuedo stereo sound seperation. And this audio circuit fully supports famicom games that use advanced audio chips. Here's a youtube video I made showing the difference in audio before/after I applied the audio mod:

The last mod I did to the av famicom system itself was I swapped out a chip with another chip that makes the system compatible with the nintendo powerpak compact flash cartridge. Here's screenshots showing that happens to the video before and after you replace the chip:

And since the powerpak outputs extended audio found in certain games and the famicom disk system I modified my nes to famicom adapter to mix that advanced audio into the system audio circuit:

If you're looking for any more information regarding my work it's easiest to contact me through my small forum here:

I hope you people enjoy my work

(I'm about 70% done commissions for the above mods for 3 clients who've already fully paid for the parts and labour. Just waiting on parts to show up.)

Very nice and absolutely amazing work, would love one of these for myself except for the fact the AV Famicom with that huge cartridge sticking out is so fugly! Still, if you are taking orders I'd be interested to know how much one of these things would cost me, is it region free too?

it's region free. I build custom kits the kit costs 140$ and the labour is 150$. Also if you want the system to work with a powerpak it's an extra 25$. And you have to pay for and find yourself an av famicom, rgb ppu, and mailing both ways. (I just sold my last extra rgb ppu chip). Oh yeah and you'd need to mail me your nes to famicom adapter so I can mod it to work with all games and so it supports expanded audio from the powerpak.

Nice work but I'm curious about your statement around the lack of video interference. i'm using a Titler PPU on the AV FC and still see the vertical lines. All of the mods I've seen (using all of the various PPUs) have the same issue to varying degrees.

Oh wait, you're the guy on the moddedbybacteria guys forum.

Do you do the mod with rgb and sound mod only? I can't really make myself get a new mod this soon after my rgb nes, but maybe for the future.

I'm gonna have to disagree with you.

In my experience the severity of the lines varies from system to system, some original NES models had virtually no lines, I have also seen AV Famicom units with faint lines, it also varies by the amplifier used, and sometimes the lines will not be visible on CRT standard res. RGB monitors, but are visible when using an XRGB. Also results vary if you are using a CRT or LCD monitor with the XRGB.

So far the best picture quality I have gotten from a modded system was a redesigned NES.

I do rgb, s-video, composite, advanced audio, powerpak compatibility chip swap, modding the nes to famicom adapter to get extended audio from the powerpak. That's all my bag of tricks for the av famicom.

Correct it's not absolutely perfect but I found it looks much better on my tv than the rgb nes with regards to jailbars. I'm not using a hd tv but for crts this system is great.

Here's a comparison video I made showing the difference of audio and video between a non modded av famicom and my upgraded one

*bump*

here's what one of my systems looks like on a flat screen.

I guess it depends on what the user is displaying their system on. I've noticed on my friend's LCD TV that even composite NES doesn't look bad because the display is doing some filtering on the video and most of the "fuzz" goes away. If you truly want to confirm the integrity of an analog system (i.e. your NES's video output), you should use an analog display (CRT) as your proof. HD TV's/Monitors are doing things to your analog signals (filtering/scaling), so a nice picture cannot be 100% attributed to your analog source.

looks crystal clear on my crt.

Here's a capture of the difference in video and audio quality

http://www.youtube.com/watch?v=7v7e-bjB ... ideo_title

The difference is this huge on my crt. I actually don't have a flat screen those above pictures were taken from a commission system I built for someone else. I mostly wanted to get these pictures to show people that my systems are very clean looking on all types of tvs.

I saw some pics from a guy on another forum's commission today, it looked pretty good. He didn't notice the jailbar issue using normal carts (this is all being sent through a dvdo edge into an hdtv), but he DID notice them (faintly) when using the powerpak - any idea why that might be?

Wow, interesting. I wonder if the power pack requires significantly more power and is starving the video output of the PPU (before it gets to the video amp. Video amp only amplifies what comes out of the PPU, so if the problem is before the amp, there's no fixing it with the amp)?

Maybe it has some relation towards problems with just getting the rgb mod to function with a powerpak in some nes revisions (with the 74HC373 ic or whatnot)

Yeah that's right the powerpak makes them a little bit more bold. Still on my crt with the powerpak I don't notice them unless I'm right infront of the tv. I have no clue what causes it. I did notice that once I installed the chip to make the powerpak work with the system that jailbars on one reproduction cart got a little worse. Really that repro cart is the only game I got jailbars from. It's rockman 1 and I only get mild jailbars in the stage select screen.

Someone mentioned on assembler (and I guess here too lol) it might be a power drawing issue - have you tried a power supply with higher amperage? The genesis power supply is 9 volts and 1.2 amps - they use that spec in those 3 in 1 console power supplies at least, and it has the same plug / polarity.

genesis 1 ac adapter works fine with the av famicom. I didn't pay attention to see if interference changed or not

If you could test that at some point, it would be appreciated.

Tried it with the genesis 1 power adapter jailbars were exactly the same as the official av famicom adapter. Jailbars were the same with both the powerpak and official carts.

Impressive. But damn dude...that's some expensive stuff. Maybe if you could get a certain amount of orders, and reduce your price for labor, you could make a higher profit that way, since more people would be buying them?

Just a thought.

I actually got tired of doing commissions of these systems so I taught my good modding friend how to build these and gave 4 commissions to him
