Here is the Final form of the S-video version of the Mod: *This does not work on all tvs, on some tvs you will need to disconnect the S-video cable to get a composite image from the adapter. This is a video Demo. A picture of my install. Not the prettiest, cleanest job but everything is sturdy ( parts are held down with dabs of hot glue). The way I did the install, It all fits on the bottom of the SNES, motherboard but you need to get rid of the bottom RF shield. Here is a different schematic, that works with composite only. The only advantage over the S-video version is that it works with all TVs. *Original first post.
