Works perfectly for my GameCube, just plug it in and didn’t need to do anything, video quality is so much better over the one I got from Walmart “onn Composite AV to HDM converter”

This was money well spent! Seriously, I was using a scrappy $13 converter that made Twilight Princess look like Vaseline was smeared all over the TV and the game was so dark that I had trouble seeing some areas. But this converter is like putting on proper glasses for the first time after having been used to bad eyesight! It even took me 30 minutes to adjust and get used to the sharpness and great resolution. The remote allows for image tweaks. I set the tv to a 4:3 aspect ratio and it looks perfect. Still doesn't beat a good old CRT, but this is still fantastic.

If you're looking for a way to get high-quality video out of your GameCube and all you've got is a modern TV, look no further. The Prism gives you nice, sharp picture quality while also being convenient and easy to use. The included remote lets you adjust some settings as well, to further tailor your visuals. There are a couple downsides: for one, you can't use this if you don't have a DOL-101 GameCube; later models of the GameCube are missing the "Digital AV" port that the Prism plugs into. The other issue is that this thing sticks pretty far out of the back of your GameCube, and it weighs down the port. You'll need to support it with something. Perhaps a Lego structure, or something 3D printed, if you have access to that sort of thing. I used a case of small dice to support mine. As long as you've got those issues covered, you're golden. I consider the Prism to be one of the best GameCube upscaler options, especially if you're looking for the easiest possible solution to poor display quality.

If you have a Gamecube with the digital port then this is the best way to play your favorite GC games. Although it's $80 it is money well spent once you see how good your games look. It's plug-n-play with any HDMI cable and requires no modding. Highly recommend!

This is a huge step up from using composite cables. It makes games look HD in comparison. There are other "cheaper" HDMI adapters but they have nowhere near the quality as this product. I believe this is currently the cheapest product if you want 480p on your Gamecube and it doesn't disappoint for the price.

Works great, no more blurry gameplay. What they don’t tell you is that for it to work properly you have to hold in the B button in your controller to put the game cube into progressive scan mode when you turn it on. then it’s 480p instead of 480i

The game cube is always was criminally under rated. Probably one of the best features that never was was the digital out for the original DOL-001 model (the port on the left shown above). While nintendo intended for this port to be used with component cables in 2024 we can use this for high quality picture output to HDMI at 480p (state of the art for 2001). The adapter has a relatively low profile sticking out slightly beyond the handle on the game cube. The device even has USB C for easy install of firmware updates. The resolution looks great with the photo being taken on a 65" OLED screen. My only complaints (and they are minor) are 1. The device uses a remote for changing options which terrifies me that I may loose it and not be able to make changes (it is working fine with settings out of the box.) 2. The device lacks extra support such as the GCHD MKII which plugs into both VGA and Digital ports for a more stable connection or the vent clipped bracket on the Kaiko adapter. That being said for the price I can live without the extra stabilizing devices.
