Yellow Dog Linux

Now that sony has nixed other os I have been trying to recreate a similar experience to that of the zerogame project on my laptop with linux. I now have wahcade up and running and working on my HDTV with my wireless sixaxis but the default layouts have little visual appeal. I was wondering if there is a web sight that hosts alternate wahcade layouts. Heck even the zerogame layout would be great if it works with the 1024x768 resolution that I am currently using. Thanks
