I gave a Genesis 3 to my gf's kids and unfortunately, the only AV cable I could find for it disintegrated within a couple of weeks. I intend to mod it with standard AV jacks to solve that problem.
While I'm in there, can someone link me to whatever mods are necessary to get Virtua Racing / Game Genie / SMS modes working? Of those, the VR is the one I'd really like to get working. The others would just be for my own personal fooling around but I have a spare VR cart and I think they might enjoy it.
