    A Needed Upgrade for Gamecube Gaming

    Posted by Hector Emmanuel Silva Benitez on Apr 26th 2021

    I have been meaning to buy this adapter for quite a while now but was hesitant due to its expensive price. Luckily, Stone Age Gamer offers a payment plan option at checkout which pushed me to buy it. Overall, I am very impressed. Gamecube games never looked better on my HD TV (Samsung). It supports progressive scan which makes the games look even better. I paired this with the MCable and I am shocked at how much you can push the Gamecube's visual quality. Installation is easy, just plug and play. I would not recommend this for everyone, as it is a hefty price, however, for those really trying to get the best quality out of their retro experience its worth buying to see for yourself.

    MK-II Greatness

    Posted by Frank on Apr 9th 2021

    I live in Sydney Australia and i was surprised how fast this product came to me. When it arrived and i opened up the delivery packaging i was fascinated with the gamecube style box which i am definitely not throwing away. I hooked up my gamecube on my LG CX65, and i used the Mk-II and i was very overwhelmed with the product. It is actually the best way you can play your old gamecube. Thanks StoneAgeGamer

    Incredibly overpriced tool, really not needed to improve the view experience

    Posted by Antonio Oliva on Aug 9th 2020

    I got my GameCube connected from my 4K Sony TV and of course, although connected via VGA cable, the viewing experience was not great, the image was very pixelated, and most of the games suffered of a sort of “Fog effect” that really made the gaming experience frustrating. Since for whatever foolish reason Nintendo still decided not to sell their blockbuster in HD with the switch, the only way to play with some great games was to resume the GameCube. I searched don the internet, and this tool came out. Although quite expansive, this adaptor claimed to fix all the issues that I found out using my 4K TV. Long story short? Almost no change at all! Still very poor image, most of the game are still vary bad looking and difficult to play...simply do not buy it! Not worth at all...

    Expensive, Awkward, But it Works!

    Posted by Dustin on Aug 8th 2020

    The HDMI port is on the side of the device, which makes it stick out at a strange angle. The product is high in price, but I understand this is an obscure market-- and given that fact, the quality is top notch. The packaging is also quite impressive. The video quality is superb, I am using it to play Gameboy games and couldn't be happier with the picture. Solid product. If the price were lower and the HDMI port were on the rear, it would be perfect.

    Great HD output for gameboy games

    Posted by Wyatt Barrier on May 1st 2020

    Used this for quite a while now with various Gameboy advance and Gameboy color games. All of them looked fantastic at 480p on every TV I tested. Absolutely love this device.

    High quality option for modern TVs

    Posted by Blake Wall on Apr 23rd 2020

    If your using this for modern HD TV's like its intended for (Which should be extremely obvious) it is an extremely good product but sure you have the correct type of Gamecube before buying.

    Anything but plug and play if you're connecting to a 480i display.

    Posted by Kyle Green on Dec 9th 2019

    So I just got one of these EON GCHD Mark II units to replace my Carby and well, I've got some thoughts. The Carby was good but HDMI out only means I can't plug it into my PVM or JVC D-Series (CRT displays). The GCHD offers a good deal of flexibility since it has both HDMI and Component outputs (via readily available Wii cables). So I can plug it into my PVM and my modern TV simultaneously! But the GCHD has some drawbacks. With great flexibility comes some complexity: Out of the box, the unit is programmed to output 480P. This is fine if you're going to be plugging it into a modern display but YMMV depending on what CRT you're plugging it into. My JVC D-Series won't display a 480p signal at all and my PVM displays a 480p signal as two images split in two. In my opinion, the unit should have been set to output 480i from the factory so it would display an image on any screen it's plugged into. Changing the output from 480p to 480i would be trivial if not for the fact that in order to do so you need to be able to access the on screen display (OSD). Unfortunately, accessing the OSD isn't possible if you're unable to see the image on screen. The instructions don't communicate any of this so my first impressions upon connecting it to my JVC CRT were that it was broken. After plugging it into another display I was able to deduce the problem and proceeded to change the display-out resolution to 480i. Navigating the OSD requires setting up an IR remote. That is, it doesn't come with one. You need to program a remote you already own to work with it. This is easy enough to do (I used the remote to my OSSC) but shouldn't be necessary. The GCHDII is $150 and the Carby is $75. The Carby comes with a remote and the GCHD does not. A simple remote to navigate the OSD should have been included at this price. On the topic of price, for $150 the GCHDII should really look and feel more robust than it does. It's not particularly solidly constructed and light from its LEDs leaks significantly through the gaps in its housing. It does the job it's supposed to and it does it well but for $150 it should be constructed with better quality materials than a $10 off the shelf Retrobit adapter. The issues it has at this price are inexcusable and despite the product being capable of what they say it can do it has shortcomings that keep me from recommending it to others.
