I'm building another supergun, which of course means I need another video encoder. I have the parts from Digikey to build the one here ( http://www.engadget.com/2006/11/28/how-to-consolize-an-arcade-game/ ), but then I realized I might have another option. Old game systems like the Genesis are probably doing this work already, so I wonder if I can get a working encoder from there? At one point I had at least half a dozen Genesises sitting around, so it probably wouldn't cost me anything if it was viable.
