But is it available to download or buy?
You wrote that you own AF2009, so you already bought it, didn't you?
The distro is Knoppix, the emulator is one of the Linux UAE derivates, don't know which, probably E-UAE.
If you are after an installation guide, search the knowledge base at amigaforever.com.
