SKU: N/A Category:


I talked Kevtris in to making us an HDMI upgrade kit for the nes and av fami consoles.

Initial announcement video:
Hi-Def NES – Kevtris’s 1080p HDMI upgrade kit is here!

There are a lot more vids, just check our channels. Kevtris Game-Tech
There are also links to the forums threads in the description of the announcement video, this is the best way to see updates as links to new vids will be posted there as well.

Not a clone system!
Uses the nintendo’s cpu and ppu.
Fully HDMI standards compliant, tested with an HDMI analyzer.

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.
EDID will allow only as high a res as the monitor will handle, but there is the option to turn it off and force higher res.

Aspect ratio will be user adjustable in the menu, seen as horizontal stretch in the menu.

Multiple palettes and a black & white mode will be user select-able in the menu.

Over clocking with hot keys with option to have it not mess up the sound pitch by following ppu clock instead of cpu.

User can reconfigure all hot keys.

Hot keys can be set to be read on either controller 1 or 2.

Long and short console reset via controller hot keys.

Updating firmware will be done via an “.nes” file, via flashcart etc, if necessary.
No need to send the console or board back to me or the installer for updates!

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 source volume independently.
User will be able to pan between left and right output of each source independently.
All expansion audio chips are programmed in to the kit, simply turn the one you need on or off.
The cart or rom you’re playing does not need the actual hardware for this to work! VID LINK

5 scaling options are included: HQ2X, HQ3X, HQ4X, scale 2X, and scale 3X.
Plus a bonus x-ray mode.

Several scanlines options: none, nes, 2x, 3x, 4x, and 5x.
Optional 4x instead of 4.5x 1080p modes to help with scanlines as well.

Easy install, desolder the cpu and ppu, add a couple wires for power, and cut out a hole using the print out template shown in the install instructions or buy the more robust template for use with a dremel (coming soon).

Tested and working with some known problem carts, multi carts, powerpak, and everdrive.

Guaranteed compatible with E, G, and H rev cpu and ppu only. This is another reason the kit will not work in the original famicom, those usually have chip revs that cause issues.

Installation not included, but here is a list of kit installers I trust to do a great job for you!

Here are the installation guides I put together.

A couple reviews of the Hi-Def NES kit have been posted online:




Unfortunately we are only hobbyist, not wal-mart, so we cannot warranty the kit unless it has been installed by one of the approved installers listed above.
We do test each kit fully though, so we can guarantee it worked fine when shipped.
We can’t control things like ESD and bad upgrade practices.
We can do repair work, just not for free.

    This masterpiece is a must own. Being able to play an original front loader on a new TV with beautiful picture and responsive controls is fantatic. Almost 2 years on the waiting and worth the wait. Invest your money into the future of your console.

    Hi-Def NES is a miracle of technology. It not only fives the best results for playing your original NES on an HD display but it is relatively simple to install, if you have experience in retro console repair or any sort of modding.

    The technology brings HD image but also great audio supporting even the most advanced audio chips!

    Shipping to eastern Canada was very fast and everything was well packed! Well worth my money! Could not be more impressed.

    Compared this mod to RGB and Frame meister and also Retro USB AVS and it stands its ground as the most advanced mod!

    If you value your NES and wish to be able to play it in the future years on any TV, this is the way to go!

    What can I say about this kit other than it’s perfect!

    The Hi-Def NES shines with top quality components and execution. All aspects of the hardware, installation, and software interface have been clearly thought through and expertly executed. The kit is complete and the installation instructions are thorough and easy to follow – just be careful when pulling those CPU & PPU chips!

    The Hi-Def NES looks amazing in HD. The image smoothing and cropping options are great features, enabling one to adjust for personal preferences and game specific needs. I’m still adjusting to how good some of these old games look on my big screen TV. Game play is perfect.

    Finally, the various functional options the Hi-Def NES provides are a nice touch and enable many opportunities for customization. Overclock, audio settings, PPU clock for sound, reset system from controller, etc.

    Thank you to Game-Tech and Kevtris for creating and distributing this kit. It has revitalized my NES and is a joy to play.

    I bought one of the first batch kits and had it installed by an approved installer. I couldn’t be happier with the product, the picture looks beautiful and the audio sounds great. I use the overclocking and reboot hotkeys way more often than I expected.

    I was also just as happy with installer Michael Smith’s work, his work well exceeded my expectations and I will use him whenever possible for future console mods.

    This mod is nothing short of amazing! I’ve falling in love with my 30 year old beloved NES console once again! It is truly a sight to be seen in person and no video does it justice really. To be able to play Lagrange Point on my NES in high definition with all the glorious sounds of the VRC7 chip is incredible in itself. Thanks to Kevtris and Game-tech for making this possible. Now if only they made a Hi-def SNES for my Super Nintendo it would be a dream come true…

    Recently got my modded system back from my modder. Of course I knew what to expect. I had seen so many screenshots and videos.

    Here’s the thing. It didn’t matter what I thought I expected. Seeing the sharpness and clarity of color in person was something I was completely unprepared for. It was exemplary.

    I am thrilled to be able to introduce my son to the games I grew up with. The service provided by Game-Tech. The hours of testing and building and designing. They have resulted in something truly special and I would like to extend my deepest gratitude to everyone involved.

    Just received and installed my hi def nes kit. It works amazing and has all my friends want me to install the kit in their systems. Kevtris and Jason should be very proud of their hard work. Thank you!!!

    Can not express in words how much I love this thing. The GREATEST thing to ever happen to an NES. This will make every one of your friends jealous. Quality beats the best emulator and spanks the Retron 5. Don’t be a software thief. Play the real thing, but with all the benefits of emulating through PC.

    Modded my NES last weekend and things went great. Most of the time (maybe an hour or two) was spent desoldering the CPU/PPU. Used solder wick to get most pins free, then hot air to free the remaining pins (mostly pins that were connected to ground planes). Just took it slow and easy, since I didn’t want to ruin either the PCB or ICs. The actual soldering up of the kit was painless and went quite fast. I ended up making the HDMI hole a bit too large. I had expected the board to slide into the post, but in reality it is pretty much just straight back.

    The product functions great. The picture is crisp (I prefer the look of the scaler off) and lag is non-existent. It is really exciting that my daughter will grow up with a console that plays the same games I played when I was a kid.

    Many thanks on the great product!

    Wonderful modernization of a classic platform! Not quite plug and play, but whether you’re good with a soldering iron, or rely on a buddy who is, it’s worth every penny. Mad props, to Game-Tech and Kevtris, for the innovation and commissioning of a wonderful distraction!

    The Hi-Def NES upgrade kit is a great, nicely designed and easy to install solution(You still need some good soldering skills). Jason made a great installed guide and Kevin is the master mind behind the kit. Thanks for your hard work!

    This kit is the real deal. Truly mind blowing. I doubt we’ll see anything in the future to top this for the NES. Thank you Kevtris for an awesome mod and thank you to Jason for the install guides and getting it out to everybody!

    This kit is brilliant, and the end results are absolutely stunning (every person I have shown it to has been blown away). It truly breathes new life into the entire NES library like nothing before and Jason was quick to respond to all of my questions. I really can’t recommend this kit enough, if you are truly serious about collecting for the NES, you must have a Hi-Def NES. Thank you again, Kevin and Jason 🙂 what you have contributed to the (NES) gaming community cannot be put into words.

    Absolutely awesome. I’ve got it in an AV Famicom, and am loving playing both carts and FDS disks, all in 1080p. It’s beautiful. And I love the option to pan the audio channels independently, which creates a pseudo-stereo sound.

    Highly recommended!

    The HighDEF NES kit, a Hakko 808 desoldering gun, and my old Top Loader NES have got me laughing at people scrambling for an NES Classic Mini!
    I have the TRUE CLASSIC!!! Hahahaha!

    Seriously, this system is the most incredible thing I’ve seen come from he retro game modding scene!
    There are not enough exclamation marks to describe how incredible this thing is!!!!!!11one

    Installation was easy, but that was also helped out by my having a proper desoldering gun. I can’t gauge how difficult desoldering the CPU and PPU would be without a desoldering tool. A Sold-a-pult should do the job just fine, but it’ll take time. With my Hakko 808… Desoldering was done in merely several minutes (it will take longer with other methods). Modding the case to allow the HDMI port to stick through was easy, and only took and x-acto knife and some patience. A file works well for final trimming. The installation was BEYOND simple!

    As for the results… Incredible! The high quality upscales in this thing rival the upscaling done by quality emulators, yet the feat is performed with exceptionally minimal lag introduced, and in full 1080p over HDMI, to your digital TV! If blocky pixels are your thing, this kit can create the sharpest edged square pixels possible. I can’t state enough just how perfect the image is. If scanlines are your thing, this kit can do that too! Other features include controller operated under and overclocking and a variety of other video and audio settings.

    Speaking of video, I recall reading that in it’s most efficient video mode, the lag is something like only 7 scanlines… That’s insane! Basically, this kit doesn’t generate a traditional frame buffer. As I understand it, it generates the HDMI data stream “on the fly”, as pixel data comes in from the NES, through the interposers, and to the main mod board. I think that’s just 1/9257th of a second of lag. That’s crazy good! Good enough to basically just say… There’s no lag!

    If you only ever buy ONE mod in your life… Make it THIS mod! It’s TRULY that great!

    Thank you Game-Tech and Kevtris for a fantastic product. I was able to mod my -001 easily, and the results are stunning. The kit was shipped quickly, the product was thoughtfully packaged, and the installation guide made the modification painless (proper tools for the job also helped). Ready to place an order for my AV Famicom for the High-Def Disk System experience. Thanks again for all of your hard work!

    I seen another reviewer above state that they were “unprepared for” the results. I find this statement to be true.
    Truly BREATHTAKING! I can’t believe how great it looks. Looks better than filtering the AV signal thru my Framemeister.
    I feel like I want to replay everything I ever played from my youth. Even this morning, the day after I installed it, I booted a game just to watch its attract move while I ate breakfast. It’s just wonderful.

    Having a quality solder sucker is a must. You could probably get away with using solder wick but of course it would be more time consuming.

    If you are a NES fan, there is only one choice– upgrade it with Hi-Def NES. This results from this kit left me speechless so I’m glad this is a written review. The hardware is excellent and the supporting install guides and videos are first rate. Thanks to Kevtris and Game-Tech. Jason at Game-Tech responded to an email on a related question quickly and was very helpful

    I’m a little above beginner in soldering skills and this was the first time to remove larger chips from PCB. Removal was a little challenging for me so I suggest getting at least a simple desoldering iron if you’re gonna go the DIY route. All other upgrade steps are simple.

    In the end it’s all about the results. You will not be disappointed.

    I absolutely love the Hi-Def NES kit. If anything the videos are underselling how great of an improvement it is.
