I'm currently not taking on any new mod work so I can prepare for Hi-Def NES work.
Nes-101 Mods I do:
The Hi-Def NES HDMI 1080p mod kit from Kevtris is here!
I talked Kevin in to making us an HDMI mod kit for the nes consoles since he already had most of it figured out on his FPGA multi system.
This is just the initial announcement of release, more info will be posted as we make it happen.[<<]]
Initial release video:
Hi-Def NES - Kevtris's 1080p HDMI mod kit is here!
Kevin's 720p video capture:
Hi-Def NES Super Mario 2 demo
Not a clone system!
Uses the nintendo's cpu and ppu.
Fully HDMI standards compliant.
No frame buffer so NO LAG between controller and monitor.
using ntsc cpu/ppu 480p, 720p, 1080p
using pal cpu/ppu 567p, 720p, 1080p
Kit will auto detect which chips it's connected to.
It will also detect if either have failed and flash a trouble code.
Will output only as high a res as the monitor will handle.
Aspect ration will be user adjustable in the menu, seen as horizontal stretch in the menu in the vid.
A few palettes will be included and user selectable in the menu.
Custom palettes can be uploaded to the nesHD using a flash cart etc.
Built in overclocking with option to not have it mess up the sound pitch
Reconfigurable hot keys to get to menu.
Console reset via controller hot keys.
Updating firmware will be done via an ".nes" file, via flashcart etc, if necessary
All audio is generated in the kit, so it will be %100 digital and theoretically noise free.
User will be able to control each audio channel from the menu.
You will be able to adjust left and right volume output of each channel independently.
Most expansion audio chips will also be programmed in to the kit and we hope to auto detect which one will be needed for a game that is being played, but may also have the option to turn each on and off.
Currently working: normal nes audio, fds, N106, mmc5, and sunsoft 5B.
VRC7 is still a maybe...
5.1 and 7.1 is also a maybe...
Might also have the ability to turn off certain channels independently.
HQX scaling is also a maybe...
Scanlines will be included, still in progress.
Possibly a built in CopyNES.
Easy instal, desolder the cpu and ppu and cut out a few mounting holes using an included template.
Tested with some known problem carts, multi carts, powerpak, and everdrive.
More testing will be done as we progress.
Kit cost will most likely be under $150 and installation by me under $100, but nothing is set yet
RGB and YPbPr mods!
VileTim's NESRGB mod kit
Cost of the hardware:
Since Tim usually sells out, I put together a big order of boards, contact me if you want to be on that waiting list.
I get the discount since it's usually more than 10 boards on the order, plus shipping is cheaper for a bigger lot.
The last batch cost each customer $83 for just the nesrgb board and nes-101 or av fami adapter boards were $5 each.
My labor charges:
$45 to instal the nesrgb and adapter board.
The instal cost also includes a new main cap (1500uF) and a new 1.5 Amp 7805 with thermal paste.
Palette switch options:
$15 for the 3 position toggle if using original RF hole.
$20 for the 3 position toggle placed somewhere where I have to drill a new hole.
$15 for the 2 position slide switch placed in the original RF hole.
$20 for the 2 position slide switch placed in a hole I have to drill elsewhere.
$25 for the 2 position slide switch placed inside the cart slot (hidden switch).
$0 if you want it on one palette only.
$50 to buy and have a 3D printed rear panel with multi out connector.
Video of me installing one, LINK
Sega genesis model 2 style connector, it doesn't carry svideo, but it's cheaper and easier to instal at $35.
$5 if you want to use the nesrgb's dual mono audio amp.
$0 to use the nes's original dual mono audio.
$15 for stereo all the time.
$20 for stereo with switch. Switch will be mounted to the left of the multi on the top shell if using the rf hole for the palette switch.
$5 for the console.
$5 for the powerpak or everdrive.
$10 for a fami converter.
Link to the nesrgb page.
Link to the shmups thread where we're all posting about it, tons of info and pics here.
I will also be testing my YPbPr (component) encoder board with this kit as soon as Tim has it ready, so that too is still an option.
This will add cost of the encoder, but zero the cost of the multi out or other connectors as I will instal the 3 gold plated rca jacks in place of the 800 sticker and a TRS headphone style jack for audio in the rf hole as usual.

Composite Video Mods:
From the factory the top loader only had an r/f hookup and its video quality is poor, that is why I mod these units with rca jack type composite outputs. You will never worry about the r/f switch going bad and being able to replace it, and history already speaks for itself! I have been modding these units since 2003! :) I've had many people ask if the lines on the tv screen, common with the top loaders, are improved with this mod and YES they are nonexistent Also, the overall picture quality is as near to a front loaders video output as it gets, they're hard to distinguish in side by side comparison. The composite output is better than the original r/f as it doesn't have to go through rf modulation or a crappy rf switch, just straight from the top loader's source video output to the tv input or whatever input you hook it up to!
The r/f output is not wired back up to keep the video output from picking up more interference, but if you want to hook it up to an old tv you can buy an r/f modulator that accepts composite video and stereo audio inputs and outputs through a coax cable to your tv's antenna input.
The picture below contains (poor) video capture of nes-001 composite output on the left, nes-101 a/v modded output in the middle,
and nes-101 unmodded r/f output on the right.
Outputs are color coded rca jacks for easy hookup. Audio right and left are wired mono since the machine is not capable of true stereo without another serious mod (read below), but both were installed for easy hook up to a home theater. I've also found an alternate method of audio/video output, instead of 3 rca jacks, I found a headphone style TRRS connector that will do the same job and fit into the r/f jack hole. This means the shell will not have to have the sticker removed and 3 holes drilled in it! Plus you will not be able to tell right away that itís even been modded. It does require a special cord, but I will supply it if this is the kind of mod you desire. There is no difference in video quality between the TRRS and 3 RCA versions of the AV mods.
Composite video and dual mono RCAx3 (the top console in first two pics) $50
Composite video and dual mono TRRS connector and 2 foot special cord (the bottom console in first two pics) $50
Composite video and dual mono TRRS connector and 5 foot special cord $53
Price includes deep cleaning shown in vids below!
DIY kits are now available through Stoneage Gamer!
LED Power Indicator
The top loader did not originally have a power LED and some owners have complained itís easy to accidentally leave the console on and not realize it. I mod the unit with a red LED light under the power slide switch that makes the slider glow when turned on, you'll never again mistakenly leave the unit on when you're done playing. If you want a different color it should be placed somewhere else, but I can put it where ever you like.
LED Power indicator $5

I have sold MANY units to UK customers, they say because of the a/v mod it works perfectly with their tv playing both US and UK games. Also have sold lots of modded consoles worldwide, same story, works great!
Click here to see a map of where I've sold modded top loaders.
Stereo and Overclock:
I also do the true stereo mod. The NES and NES2 have the same chip for audio out and that chip has two audio output channels and thats what the mod exploits, it may not sound right on every game, but I have mods that allow you to mix or switch it all the way back to dual mono for games that don't sound right. Its supposed to be great for Zelda and many others, i'm trying to find a list of what works and doesn't.
I actually have 3 versions of this mod. First uses a potentiometer, turn the knob all the way one way for full stereo and all the way the other for full mono and in-between to your preference.
What I found was most people don't really use it for in between, so why not replace that pot with a switch! So that's the second version. It allows us to change between stereo and dual mono, but also leaves the RF jack hole open so we can instal the TRRS version of the AV mod!
Lastly, I can wire it up for full stereo all the time. This will allow us to instal the overclock and TRRS AV mods!
True Stereo with MIX KNOB - ON HOLD until I can find a pot that won't every other time!
True Stereo with SWITCH - $20
True Stereo all the time - $15
The over-clock mod is just like over-clocking computers, it makes the processor run faster, in this case only 32% faster. This is useful for games that slow down when there is a lot going on in the game. The mod does have a down side, the audio is also affected, itís like listening to it in fast forward, but itís just a pitch increase. I install a switch to change between normal and over-clock modes in the 3-4 channel select hole and since its such a little increase its usually easily changed from normal to over-clock and back while the game is running without it crashing! Since the processor runs faster you might think the games go faster, but I timed SMB and it took 2 minutes and 40 seconds for 400 units of time in the game to run out in both normal and over-clocked.
Over-clock mod - $20
Youtube videos of the stereo and over-clock mods:

This pic shows the stereo mixing knob mounted in the hole the r/f out jack used and the over-clock switch mounted in what was the 3-4 channel select switch hole.
This mod is now obsolete! There are save state mappers for the PowerPak that accomplish game and console reset in a similar fashion as the mod explained below, however it is still available for those that play a lot of multi-carts.
This mod will make it possible to reset the console by pushing 4 buttons on the controller at the same time, A+B+Start+Select.
This will be mostly useful on multi-carts since you have to reset the console to reboot the cart in order to play a different game.
Also useful for the PowerPak which works in a similar manner.
It does not affect the way PowerPak saves game or the way save state mappers function!
Its super small and mostly surface mount parts so really hard to solder so if I sell it as a DIY kit it will be in complete ready to solder in form only.
Price for DIY kit should be around $50, $55 if you send your top loader to me to solder it in.
Youtube video of the remote reset mod:

The PowerPak is awesome, but it doesn't always work with a modded top loader because of one chip, the 74LS373.
If you replace that chip with the HC373 version it will work fine.
Usually only a problem with pc10 rgb/component modded consoles, not an issue with the nesrgb kit.
It's only happened a couple times, but i've had it not work with composite modded top loaders as well, but I test all the nes consoles I work on with a powerpak and if it doesn't work i'll let you know it needs this mod as well.
If you need the chip changed i'll do it for $10.
Youtube video proof of the problem:

PowerPak Mods - Famicom Expansion Audio:
Some roms have extra sound that can't be heard unless the PowerPak and your NES-101 are modded.
PowerPak mod - $5
NES mod - $5

The are 5 electrolytic caps in the nes-101, but only two have ever caused problems on the dozens of broken units i've fixed.
One is used for the reset circuit and rarely causes problems.
The main problem cap is in the power circuit, i've replaced at least 50 of these over the years.
It's going to fail eventually, they are not made to last forever and caps in the power circuit get worked hard at higher temps.
I will replace either cap for $2 each if i'm already doing other mods on the console! Too cheap to not have it done!!!
$5 for the power cap if i'm not doing other mods, $7 for both if i'm not doing other mods.
This is the cheapest insurance that your top loader will last another 25 years!
Here is a pic of what the image on the tv will look like when the power cap fails:

Old RGB options:
I've done 30 or more rgb consoles using the rgb ppu from a playchoice 10, but it's rather expensive compared to the new kit from Tim, but if that's what you want I can still do it for you.\\
If you get a hold of a Playchoice 10 arcade board or certain VS's boards or games you can steal the RGB PPU and use it in an NES and have RGB out or component(YPbPr) and even s-video if wanted. The color palette is not %100 the same so there will be minor differences. There also seems to be minor glitches here and there, like just a short line of pixels acting up, but it's not every game and not every scene on games that do show it. Also the jailbars are nearly impossible to get rid of, but not near the level of top loader rf output.
RGB PPU nor the console are included in modification costs quoted below!
Parts and labor cost for:
NES-101 with multi out with amplified rgb, cleaned sync, and dual mono audio - $100
NES-101 with multi out with amplified rgb, cleaned sync, and stereo all the time - $110
NES-101 with multi out with amplified rgb, cleaned sync, and stereo audio with switch or mix knob- $120
Customer must supply the multi out connector, must be from a SNES!
NES-101 with component and 3 gold plated color coded rca output jacks - $100
There is no room left for audio rca jacks so a TRS (1/8" headphone) jack must be used in the RF jack hole or elsewhere - $15 for dual mono - $20 for full stereo all the time - $25 for stereo with switch.
There is a way to have the mix knob version if you're ok with the TRS jack being placed to the far left, opposite the 3 component jacks.
I can only get the TRS jack in black, so its a bit out of place, but at least its in the rear of the console...

Breakdown for top loader/nes/fami repairs:
$15 trouble shooting fee even if I can't fix it (has never happened).
These fees are only applied to the bill if they are bad and have to be replaced:
$15 per chip for cpu or ppu.
$10 per chip for sram.
$2 per capacitor.
$5 for 7805 regulator.
$30 + $1 per pin to change pins in the 72 pin connector (its a lot of work to remove the whole thing to get to the pins, bent pin can usually be salvaged without having to be replaced).
$60 to swap out the whole nes-101 motherboard (only happens if it's cracked or too many traces are corroded beyond repair etc).
NES Accessory Mods:
I also do NES Dogbone controller mods:
Prices for the services - controller not included:
$10 per controller for dogbone controllers, button indicators only.
Youtube video of the Dogbone LEDs mod in action:

I've done over 800 composite mods since 2003!
Since starting them in early 2012, i've done over 50 rgb or component NES consoles!
Recent customer review:
It used to be that you can either have the better picture of the NES front loader or the ease/convenience of the top loader; you couldn't have both. But now with my new AV modded NES top loader, I can have the best of both worlds! The picture is so crystal clear on our Sharp Aquos HDTV and the red LED light is a nice touch too. I now can't imagine playing NES games any other way. I highly recommend his NES top loaders and no serious NES gamer should be without one.
