Looks like just what i needed. However, i couldn't find much information about it on your site. What kind of systems does it support apart from PS1 and arcade machines? SNES? NES? Megadrive? What kind of controllers? Xbox 360? How are ROMS loaded? USB?
Answers to these questions should be easily accessible to any prospective user (i don't have my Pi available to test the distro), but then again, i suspect this project only started very recently and you're already planning on updating the website.
