I have officially posted what I come to name SegaGEN on the site. There is a page for it on the left. This thing is quite awesome. I have built it with quite a few games. But, the one that comes with games is about 50mb. The one without games but quite hard to make is about 2mb. You can download them both with the instructions on the page created for it. I wish I could post screen shots of how awesome this is.
