Have you noticed that the popular GC Video HDMI dongles for the Gamecube sag when a heavy HDMI cable is plugged into it? This simple brace latches onto the Gamecube vents below the Digital Video port and support the dongle from sagging. It keeps sticking out horizontally from the rear of the console.
There are 3 versions:
Carby - works with the Insurrection Industries Carby HDMI dongle, their Component video cable, as well as the original GameCube component cable (OEM)
Prism - works with the Retrobit Prism HDMI dongle and the Prism Component cables.
GCHD mkII - works with the Eon GCHD mkII.
Remove your Carby or Prism and this brace fit into the vents and rotates into place. Please see pictures.
