GCDual is the ultimate AV upgrade for your classic Nintendo Gamecube console. Free yourself from expensive component cables and analogue only connections with this all in one solution. GCDual adds the following features to your classic console:-
HDMI output – Full HDMI output including audio, with optional line doubling of 240p/480i sources and optional scanlines. Note that GCDual uses a Mini HDMI port.
Full analogue output – Output ANY Gamecube resolution via the standard analogue port. Need 480p via SCART for your OSSC or XRGB Mini? No problem! It’s also possible to get RGB output for NTSC consoles.
No more rare and expensive component cables – Use a standard SNES SCART cable with a breakout adapter for component (YPbPr) video.
OSD control – Access GCDual’s settings from a convenient OSD which works via a standard Gamecube controller. To activate the OSD, hold the L, R, X and Y buttons down until the menu appears.
The Nintendo Gamecube GCDual upgrade powers up your classic console with a fully digital HDMI output port that supports both video and audio. All Gamecube screen modes are supported, 240p can be line-doubled to 480p for full HDMI compatibility, while interlace modes can be either line doubled or sent directly to the display. All line-doubling is done on the fly, there’s no frame buffer and therefore no input lag.
To learn more about this fantastic mod, check out our review of the original HDMI Gamecube mod here, and our updated review/overview of GCDual’s new features here.
Remember, in order for your Gamecube to be compatible with this mod, it MUST have the “Digital AV Out” port at the back of the console. Later model Gamecube consoles that do not have this port are unfortunately not compatible.
Note – GCDual configuration jumpers – Unless otherwise instructed we will set up your GCDual for use with a standard CSYNC Nintendo RGB SCART cable that has an attenuation resistor on the sync connection. This is the correct setting for 99% of users. If you need a different configuration please let us know, but please be sure you understand what you need. All available options are documented here.
This mod provides audio and video through the HDMI cable, but a very small number of HDTVs may be incompatible with audio/video mode. In this case, audio can be disabled through HDMI and routed through the consoles analogue output to a suitable receiver as normal.

Timothy Joyce –
For quite a long time I was eager to improve the picture quality on my GameCube and living in the UK it’s easier said than done. I decided it would be far too costly to achieve so I gave up on it eventually. That is of course until Nintendo Life reviewed this newly released mod and gave it top marks, so I decided I would have to try it. I can safely say that anyone who wants to up the ante and upgrade their GameCube should buy this mod. The picture quality is astounding especially when you compare it with an RGB scart cable, the two simply don’t compare! I tested a number of PAL region games such as Soulcalibur II, Super Mario Sunshine and Skies of Arcadia Legends and all of them showcased enhanced detail and cleaner pictures overall. Not to mention the improved audio fidelity which is instantly noticeable on first hearing. Customer service was exemplary, all my emails got a quick response and I was given regular updates too, top notch! I am also very pleased to see that the price of the mod has also come down in price substantially making this the definitive option over the component cable (which tend to go for some pretty high pennies on ebay). Yes if you live in the UK or anywhere else where your GameCube games don’t support 480p then invest in this mod, you won’t regret it.
Admin response – Thanks for the kind review! Please note that this mod only performs a simple line-double for 480i games so it’s no substitute for actually running Gamecube software in 480p.
