I just picked this up off one of the forum members with a few other SNES games, I figured I'd share the information I had with some pics since I can't really find much online.
I haven't tried it yet... any guesses what the small port on the back is for? Reading the article it mentions a ram cart addon... maybe that's it. I'm going to try it with some PAL games and various combinations of systems to see if it can do some magic.
Here's the link (Vectorman is the greatest link finder ever) found with the device info:

And here are the pics!
