Boot. Play! Retro-style

Give that old PC a new life by turning it into a retro gaming console with the KnoppiXMAME Live CD Linux Distro.

KnoppiXMAME is a bootable CD/DVD image with hardware automatic probing and configuration for playing MAME games. No games are included, but they can be added to the ISO image, as well as new versions of X-MAME, gxmame, and the Linux kernel”

Of course you’ll need to legally obtain a few MAME ROMs, but you knew that anyway ;-)
