I've been waiting for this for ages!

X-Amiga has been released - a BETA download of an emulated Classic Amiga environment for standard PCs, all thanks to Amir Ansari (Fractallyte) who put the pack together in an easy-to-install ISO image.
Why is it special? Well, this is a very lite Linux distribution that only contains the required files to boot a PC directly into an emulated Amiga and Workbench environment (default is AmigaSYS I think).
Of course, this isn't the first of these kinds of packs, but this one sounds like it's building up to be the best.
I haven't tried it yet, but just imagine being able to use cheap PC hardware to boot directly into a Classic Amiga environment, with classic games and software compatibility. You can turn your aging PC into a nice Classic Amiga!
The main downside will be how mature the Linux version of UAE is, as it's bound to not be as polished or easy to use as WinUAE. Still, I hold high hopes for this project moving forwards.
