I didn't take many pics while I was doing it. I might pull it apart again to take a pic of the 50/60 switch mod.
So here's what I got. First pic is the composite out wiring. I didn't want to bother with S-video (which is that mod plus some extra stuff) because you have to make a small amp for the S-video, which to me is too much work

And besides, the CRT's I have don't even have S-video inputs. It might be something I do to hook this up to the 40" LED one day. I hooked my modded SMS up to it, and it looks much like it does unmodded on a 51cm telly...
Aesthetically, I think it would have looked better with the RCA plugs and the switch swapped around. But since you don't see the back much, it doesn't matter much. As suggested on Stickfreaks site, I added the extra audio plug so that I'm using both speakers on the tv.
This has been so worth it for me. The SMS is my least used system because it's a hassle with the aerial set up. Now I have a games room, and it can be hooked up on a switcher with my other old consoles. I get the feeling that the others are going to be unloved for a little while.
